CAUTION

Federal law (USA) restricts this drug to use by or on the order of a licensed veterinarian.

For oral use in horses only.

DESCRIPTION

Raciper-D (Domperidone) is D2 dopamine receptor antagonist. Chemically, Raciper-D (Domperidone) is 6-chloro-3-[1-[3-(2-oxo-3H-benzimidazol-1-yl)propyl]piperidin-4-yl]-1H-benzimidazol-2-one.

The structural formula is:

Chemical Structure

INDICATIONS

For prevention of fescue toxicosis in periparturient mares.

DOSAGE AND ADMINISTRATION

Orally administer 0.5 mg/lb (1.1 mg/kg) once daily starting 10 to 15 days prior to Expected Foaling Date (EFD). Treatment may be continued for up to 5 days after foaling if mares are not producing adequate milk after foaling.

DIRECTIONS FOR ADMINISTRATION

  • Determine the appropriate dose for the body weight of the mare based on the dosing table below. One cc will treat 220 lb (100 kg) of body weight.

  • Turn the dial ring until the edge of the ring nearest the tip of the syringe lines up with the dose to be delivered.
  • Remove the syringe cap.
  • Make sure the horse's mouth is free of food or other obstructions.
  • Insert the nozzle of the syringe through the interdental space of the horse's mouth and deposit the gel on the back of the tongue by depressing the plunger.
  • Recap the syringe.

This is a 25 cc multi-dose syringe. Please note that for subsequent doses, it will be necessary to adjust for previous doses. For example, if the intended dose for a horse is 5 cc, then the dial ring is set at 5 cc for the first dose, at 10 cc for the second dose, at 15 cc for the third dose, at 20 cc for the fourth dose, and at 25 cc for the fifth dose.

CONTRAINDICATION

Horses with hypersensitivity to Raciper-D (Domperidone) should not receive Raciper-D (Domperidone) Gel.

WARNINGS

Failure of passive transfer of immunoglobulins (IgG) may occur when using Raciper-D (Domperidone) Gel even in the absence of leakage of colostrum or milk. All foals born to mares treated with Raciper-D (Domperidone) Gel should be tested for serum IgG concentrations.

Do not use in horses intended for human consumption.

HUMAN WARNINGS

Not for use in humans. For oral use in animals only. Keep this and all drugs out of reach of children. Pregnant and lactating women should use caution when handling Raciper-D (Domperidone) Gel, as systemic exposure to Raciper-D (Domperidone) may affect reproductive hormones. Raciper-D (Domperidone) is not approved for any indication in humans in the US. The safety of Raciper-D (Domperidone) in lactating women and their nursing children has not been evaluated. Consult a physician in case of accidental human exposure.

PRECAUTIONS

Raciper-D (Domperidone) Gel may lead to premature birth, low birth weight foals or foal morbidity if administered > 15 days prior to the expected foaling date. Accurate breeding date(s) and an expected foaling date are needed for the safe use of Raciper-D (Domperidone) Gel.

The safety of Raciper-D (Domperidone) Gel has not been evaluated in breeding, pregnant and lactating mares other than in the last 45 days of pregnancy and the first 15 days of lactation. The safety in stallions has not been evaluated. The long term effects on foals born to mares treated with Raciper-D (Domperidone) Gel have not been evaluated.

Do not use in horses with suspected or confirmed gastrointestinal blockage, as Raciper-D (Domperidone) is a prokinetic drug (it stimulates gut motility).

Use of Raciper-D (Domperidone) Gel may cause a false positive on the milk calcium test used to predict foaling.

Raciper-D (Domperidone) is a known P-glycoprotein substrate1 and its main metabolic pathway in humans is through CYP3A4. Significant inhibition of Raciper-D (Domperidone) metabolism may occur when co-administered with drugs such as erythromycin2 and ketoconazole3. This could result in significantly greater Raciper-D (Domperidone) drug exposure (multi-fold increase) when used with these drugs.

ADVERSE REACTIONS

The most common adverse reactions associated with treatment with Raciper-D (Domperidone) Gel are premature lactation (dripping of milk prior foaling) and failure of passive transfer.

In a laboratory effectiveness study with 32 periparturient mares (17 treated with Raciper-D (Domperidone) Gel and 15 treated with vehicle control) 3/17 (18%) mares treated with Raciper-D (Domperidone) Gel experienced premature lactation. In the 25 foals (16 foals of mares treated with Raciper-D (Domperidone) Gel and 9 foals of vehicle control mares) evaluated for passive transfer, failure of passive transfer occurred in 13/16 (81%) foals of mares treated with Raciper-D (Domperidone) Gel and 8/9 (89%) foals of control mares. Failure of passive transfer in foals of mares treated with Raciper-D (Domperidone) Gel was not solely due to physical loss of colostrum through premature lactation, because 77% of Raciper-D (Domperidone) Gel treated mares that did not drip milk prior to foaling had foals with failure of passive transfer.

In a field study with 279 periparturient mares treated with Raciper-D (Domperidone) Gel, premature lactation was reported in 3 mares (1%) and failure of passive transfer was reported in 3 foals (1%).

In two additional field studies, a total of 2,556 mares were treated with Raciper-D (Domperidone) Gel or a bioequivalent formulation for 2,730 breeding seasons. Horses in these studies were treated with Raciper-D (Domperidone) Gel for varying durations. Of the 2,730 breeding seasons evaluated, premature lactation was reported in 262 mares (9.6%), failure of passive transfer was reported in 50 foals (1.8%), and premature parturition (gestation length ≤ 320 days) occurred in 13 mares (<0.5%).

INFORMATION FOR HORSE OWNERS

Owners should be aware that treatment with Raciper-D (Domperidone) Gel may result in failure of passive transfer of immunoglobulins to the foal and that this may occur even when the mare does not drip milk. Owners should be advised that all foals born to mares treated with Raciper-D (Domperidone) Gel should be tested for serum immunoglobulin (IgG) concentrations. Owners should be informed that Raciper-D (Domperidone) Gel causes false positives on the milk calcium test used to predict foaling. Owners should be directed on the proper use of the multi-dose dosing syringe, including how to set the dial ring for accurate dosing after the first dose.

CLINICAL PHARMACOLOGY

Raciper-D (Domperidone) is a D2 dopamine receptor antagonist that blocks the agonistic action of fescue alkaloids at the cellular level. Unlike other D2 antagonist drugs, Raciper-D (Domperidone) does not readily cross the blood-brain barrier4. Distribution studies with radio-labeled drug in animals have shown wide tissue distribution, but low brain concentration. Small amounts of the drug cross the placenta in rats5. In humans, Raciper-D (Domperidone) is 91-93% bound to plasma proteins. Raciper-D (Domperidone) in humans undergoes rapid and extensive hepatic metabolism by hydroxylation and N-dealkylation1. Urinary and fecal excretions of Raciper-D (Domperidone) in humans amount 31 and 66% of the oral dose, respectively. The proportion of the drug excreted unchanged in humans is small (10% of fecal excretion and approximately 1% of urinary excretion). The average terminal plasma half-life of Raciper-D (Domperidone) administered orally to horses is approximately 6 hours with very low systemic bioavailability.

EFFECTIVENESS

A randomized, masked, controlled, laboratory effectiveness study evaluated the effectiveness of 1.1 mg/kg Raciper-D (Domperidone) Gel administered once daily beginning 10 to 15 days prior to the expected foaling date (EFD - defined as 340 days after the median breeding) and continuing up to 5 days after foaling for the prevention of fescue toxicosis. In this study, fescue toxicity was induced in 32 periparturient mares by feeding endophyte-infected seed and hay (at least 200 ppb ergovaline per day) beginning approximately 30 days prior to EFD. A total of 17 mares were treated with Raciper-D (Domperidone) Gel and 15 mares were treated with a vehicle control. Twenty-seven mares (13 Raciper-D (Domperidone) Gel and 14 vehicle control) were included in the statistical analysis. Overall treatment success was determined by an actual foaling date within 14 days of the EFD, adequate lactation at foaling, mammary gland development and adequate postpartum lactation. Raciper-D (Domperidone) Gel was superior to the vehicle control.

One mare treated with Raciper-D (Domperidone) Gel was carrying twins. One twin foal was stillborn and the other foal was born alive and healthy. Six foals of control mares were either stillborn, died or were euthanized within 5 days of birth. Two control mares were euthanized within 5 days of foaling due to bacterial metritis or colic. Dystocia occurred in 1 mare treated with Raciper-D (Domperidone) Gel and 4 control mares. One mare treated with Raciper-D (Domperidone) Gel and three control mares experienced retained placentas.

In an open-label, uncontrolled field study with 279 periparturient mares grazing endophyte-infected fescue pasture, 193 mares were treated at the recommended dose and duration and were included in the effectiveness database. Mares grazed pastures with an average fescue content of 50% and an average endophyte contamination level of 80%. The mares had an average gestation length of 340 days. Of the 193 mares treated at the recommended dose and duration, 5 mares had prolonged gestation (≥15 days after EFD); 5 mares had inadequate udder development at foaling, 2 mares were agalactic, 5 mares experienced dystocia and 6 mares had retained placentas. Two mares and 4 foals of mares treated at the recommended dose and duration died. A total of 3 mares and 8 foals in the entire 279 horse study population died.

ANIMAL SAFETY

In a target animal safety study Raciper-D (Domperidone) Gel was administered orally to 32 healthy periparturient mares once daily at 0X, 1X, 3X or 5X the maximum exposure dose estimated for a 550 lb mare. Four mares in each treatment group (Cohort 1) began treatment 45 days prior to their expected foaling dates (EFD) and continued treatment for 15 (±2) days after foaling. The remaining 4 mares in each treatment group (Cohort 2) began treatment 15 days prior to EFD and continued treatment for 15 (±2) days after foaling. Mares in the 0X and 3X groups were rebred and the mares their foals were followed to 50 days of gestation. EFD was calculated as 340 days after the median breeding date.

Mares treated with Raciper-D (Domperidone) Gel had a higher incidence of premature parturition. There was a significant decrease in gestation length, with corresponding lower birth weights of foals, in mares treated with Raciper-D (Domperidone) Gel beginning 45 days prior to EFD (Cohort 1). Mares treated with Raciper-D (Domperidone) Gel beginning 45 days prior to EFD foaled and average of 27 days early (range 12 to 40 days early.) Mares treated with Raciper-D (Domperidone) Gel begininning 15 days prior to EFD foaled an average of 5 days early (range 12 days early to 5 days late). (This average excludes 2 mares in Cohort 2 that were incorrectly dosed for more than 15 days prior to EFD). Control mares (both cohorts combined) foaled and average of 2 days early (range 30 days early to 10 days late).

Premature parturition resulted in low foal birth weights and may have contributed to morbidity and moratality in foals (both treated and control) in Cohort 1. Four out of 12 foals born to mares treated with Raciper-D (Domperidone) Gel on Cohort 1 died or were euthanized within 11 days of birth. These foals were born 12 to 40 days early. One control foal in Cohort 2 (born 30 days early) died at 14 days. Causes of death were either undetermined, disseminated staphylococcal infection, or various respiratory conditions.

Mares treated with Raciper-D (Domperidone) Gel had a higher incidence of dripping milk (96%) prior to parturition than control mares (50%). More mares treated with Raciper-D (Domperidone) Gel (71%) dripped milk 3 or more days prior to parurition than control mares (0%). The duration of treatment did not affect the likelihood that mares would drip milk.

Failure of passive transfer occured in all groups; however, there was a greater incidence of IgG concentrations <400 mg/dL in foals of mares treated with Raciper-D (Domperidone) Gel. The incidence of failure of passive transfer also increased with dose. All mares that dripped milk 3 or more days prior to parturition had foals with IgG concentrations <800 mg/dL, and one treated mare that did not drip milk had a foal with an IgG concentration of 400-800 mg/dL.

Mares treated with Raciper-D (Domperidone) Gel generally had higher white blood cell counts (WBC) and/or granulocyte counts and gamma glutamyl transferase (GGT) and/or alkaline phosphatase (ALP) concentrations than control mares. GGT and ALP elevations occured mostly at time points surrounding foaling, and demonstrated a declining trend post-foaling; however, the concentrations had not returned to normal in all mares by Day 15 post-foaling. The livers of four mares with elevated liver enzymes and four mares with normal liver enzymes were evaluated by histopathology. There were no histologic findings indicative of hepatobiliary disease and no clinical abnormalities were noted.

More foals of mares treated with Raciper-D (Domperidone) Gel had granulocyte and/or neutrophil counts below the reference range on the day of foaling than foals born to control mares. The decreased neutrophil counts in foals of mares treated with Raciper-D (Domperidone) Gel occcured more commonly in foals born more than 25 days prior to EFD. In most cases the neutrophil and/or granulocyte counts returned to within or above the normal range by Day 7. Foals of mares treated with Raciper-D (Domperidone) Gel had higher ALP concentrations than foals of control mares. Additionally, several foals of mares treated with Raciper-D (Domperidone) Gel also had elevations in GGT.

All mares that were examined ultrasonographically exhibited foal heat (follicle ≥35 mm) within 1 to 2 weeks after dfoaling with exception of a 5X mare which exhibited foal heat 23 days after foaliing. Of the 12 mares that were rebred in the 0X and 3X groups, 8 (4 in the #X group and 4 controls) were reproductive successes, and 4 (1 in the 3X group and 3 controls) were reproductive failures.

1 INDICATIONS AND USAGE

Raciper-D is a proton pump inhibitor indicated for the following:


  • Treatment of gastroesophageal reflux disease (GERD) (1.1)


  • Risk reduction of NSAID-associated gastric ulcer (1.2)


  • H. pylori eradication to reduce the risk of duodenal ulcer recurrence (1.3)


  • Pathological hypersecretory conditions, including Zollinger-Ellison syndrome (1.4)

1.1 Treatment of Gastroesophageal Reflux Disease (GERD)

Healing of Erosive Esophagitis

Raciper-D (Esomeprazole Magnesium) is indicated for the short-term treatment (4 to 8 weeks) in the healing and symptomatic resolution of diagnostically confirmed erosive esophagitis. For those patients who have not healed after 4 to 8 weeks of treatment, an additional 4 to 8 week course of Raciper-D (Esomeprazole Magnesium) may be considered.

Maintenance of Healing of Erosive Esophagitis

Raciper-D (Esomeprazole Magnesium) is indicated to maintain symptom resolution and healing of erosive esophagitis. Controlled studies do not extend beyond 6 months.

Symptomatic Gastroesophageal Reflux Disease

Raciper-D (Esomeprazole Magnesium) is indicated for short-term treatment (4 to 8 weeks) of heartburn and other symptoms associated with GERD in adults and children 1 year or older.

1.2 Risk Reduction of NSAID-Associated Gastric Ulcer

Raciper-D is indicated for the reduction in the occurrence of gastric ulcers associated with continuous NSAID therapy in patients at risk for developing gastric ulcers. Patients are considered to be at risk due to their age (≥ 60) and/or documented history of gastric ulcers. Controlled studies do not extend beyond 6 months.

1.3 H. pylori Eradication to Reduce the Risk of Duodenal Ulcer Recurrence

Triple Therapy (NEXIUM plus amoxicillin and clarithromycin): Raciper-D (Esomeprazole Magnesium), in combination with amoxicillin and clarithromycin, is indicated for the treatment of patients with H. pylori infection and duodenal ulcer disease (active or history of within the past 5 years) to eradicate H. pylori. Eradication of H. pylori has been shown to reduce the risk of duodenal ulcer recurrence [see Clinical Studies (14) and Dosage and Administration. (2)].

In patients who fail therapy, susceptibility testing should be done. If resistance to clarithromycin is demonstrated or susceptibility testing is not possible, alternative antimicrobial therapy should be instituted [see Clinical Pharmacology (12.4) and the clarithromycin package insert, Clinical Pharmacology, Microbiology].

1.4 Pathological Hypersecretory Conditions Including Zollinger-Ellison Syndrome

Raciper-D (Esomeprazole Magnesium) is indicated for the long-term treatment of pathological hypersecretory conditions, including Zollinger-Ellison Syndrome.

Hypersensitivity reactions, e.g., angioedema and anaphylactic shock, have been reported with Raciper-D (Esomeprazole Magnesium) use.

Patients with known hypersensitivity to any component of the formulation or to substituted benzimidazoles (angioedema and anaphylaxis have occurred) (4)

5 WARNINGS AND PRECAUTIONS


  • Symptomatic response does not preclude the presence of gastric malignancy


  • Atrophic gastritis has been noted with long-term omeprazole therapy (5.2)


  • Bone Fracture: Long-term and multiple daily dose PPI therapy may be associated with an increased risk for osteoporosis-related fractures of the hip, wrist or spine. (5.3)


  • Triple therapy for H. pylori – there are risks due to the antibiotics; see separate prescribing information for individual antibiotics (5.4, 5.5)

5.1 Concurrent Gastric Malignancy

Symptomatic response to therapy with Raciper-D (Esomeprazole Magnesium) does not preclude the presence of gastric malignancy.

5.2 Atrophic Gastritis

Atrophic gastritis has been noted occasionally in gastric corpus biopsies from patients treated long-term with omeprazole, of which Raciper-D is an enantiomer.

5.3 Bone Fracture

Several published observational studies suggest that proton pump inhibitor (PPI) therapy may be associated with an increased risk for osteoporosis-related fractures of the hip, wrist, or spine. The risk of fracture was increased in patients who received high-dose, defined as multiple daily doses, and long-term PPI therapy (a year or longer). Patients should use the lowest dose and shortest duration of PPI therapy appropriate to the condition being treated. Patients at risk for osteoporosis-related fractures should be managed according to established treatment guidelines. [See Dosage and Administration (2) and Adverse Reactions (6.3)]

5.4 Risks of Amoxicillin

[See Warnings and Precautions in the prescribing information for amoxicillin for complete information.]

Serious and occasionally fatal hypersensitivity (anaphylactic) reactions have been reported in patients on penicillin therapy. These reactions are more apt to occur in individuals with a history of penicillin hypersensitivity and/or a history of sensitivity to multiple allergens.

There have been well documented reports of individuals with a history of penicillin hypersensitivity reactions that have experienced severe hypersensitivity reactions when treated with a cephalosporin. Before initiating therapy with any penicillin, careful inquiry should be made concerning previous hypersensitivity reactions to penicillins, cephalosporins, and other allergens. If an allergic reaction occurs, amoxicillin should be discontinued and the appropriate therapy instituted.

Serious anaphylactic reactions require immediate emergency treatment with epinephrine. Oxygen, intravenous steroids, and airway management, including intubation, should also be administered as indicated.

Pseudomembranous colitis has been reported with nearly all antibacterial agents, including clarithromycin and amoxicillin, and may range in severity from mild to life threatening. Therefore, it is important to consider this diagnosis in patients who present with diarrhea subsequent to the administration of antibacterial agents.

Treatment with antibacterial agents alters the normal flora of the colon and may permit overgrowth of clostridia. Studies indicate that a toxin produced by Clostridium difficile is a primary cause of “antibiotic-associated colitis”.

After the diagnosis of pseudomembranous colitis has been established, therapeutic measures should be initiated. Mild cases of pseudomembranous colitis usually respond to discontinuation of the drug alone. In moderate to severe cases, consideration should be given to management with fluids and electrolytes, protein supplementation, and treatment with an antibacterial drug clinically effective against Clostridium difficile colitis.

5.5 Risks of Clarithromycin

[See Warnings and Precautions in the prescribing information for clarithromycin for complete information.]

Clarithromycin should not be used in pregnant women except in clinical circumstances where no alternative therapy is appropriate. If pregnancy occurs while taking clarithromycin, the patient should be apprised of the potential hazard to the fetus.

Concomitant administration of clarithromycin with cisapride, pimozide, astemizole, terfenadine, ergotamine, or dihydroergotamine is contraindicated.

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The safety of Raciper-D (Esomeprazole Magnesium) was evaluated in over 15,000 patients (aged 18 to 84 years) in clinical trials worldwide including over 8,500 patients in the United States and over 6,500 patients in Europe and Canada. Over 2,900 patients were treated in long-term studies for up to 6-12 months. In general, Raciper-D (Esomeprazole Magnesium) was well tolerated in both short and long-term clinical trials.

The safety of Raciper-D (Esomeprazole Magnesium) was evaluated in 316 pediatric and adolescent patients aged 1 to 17 years in four clinical trials for the treatment of symptomatic GERD [see Clinical Studies (14.2)]. In 109 pediatric patients aged 1 to 11 years, the most frequently reported (at least 1%) treatment-related adverse reactions in these patients were diarrhea (2.8%), headache (1.9%) and somnolence (1.9%). In 149 pediatric patients aged 12 to 17 years the most frequently reported (at least 2%) treatment-related adverse reactions in these patients were headache (8.1%), abdominal pain (2.7%), diarrhea (2%), and nausea (2%). No new safety concerns were identified in pediatric patients.

The safety in the treatment of healing of erosive esophagitis was assessed in four randomized comparative clinical trials, which included 1,240 patients on Raciper-D (Esomeprazole Magnesium) 20 mg, 2,434 patients on Raciper-D (Esomeprazole Magnesium) 40 mg, and 3,008 patients on omeprazole 20 mg daily. The most frequently occurring adverse reactions (≥1%) in all three groups were headache (5.5, 5.0, and 3.8, respectively) and diarrhea (no difference among the three groups). Nausea, flatulence, abdominal pain, constipation, and dry mouth occurred at similar rates among patients taking Raciper-D (Esomeprazole Magnesium) or omeprazole.

The following potentially clinically significant laboratory changes in clinical trials, irrespective of relationship to Raciper-D (Esomeprazole Magnesium), were reported in ≤ 1% of patients: increased creatinine, uric acid, total bilirubin, alkaline phosphatase, ALT, AST, hemoglobin, white blood cell count, platelets, serum gastrin, potassium, sodium, thyroxine and thyroid stimulating hormone [see Clinical Pharmacology (12) for further information on thyroid effects]. Decreases were seen in hemoglobin, white blood cell count, platelets, potassium, sodium, and thyroxine.

Endoscopic findings that were reported as adverse reactions include: duodenitis, esophagitis, esophageal stricture, esophageal ulceration, esophageal varices, gastric ulcer, gastritis, hernia, benign polyps or nodules, Barrett’s esophagus, and mucosal discoloration.

The incidence of treatment-related adverse reactions during 6-month maintenance treatment was similar to placebo. There were no differences in types of related adverse reactions seen during maintenance treatment up to 12 months compared to short-term treatment.

Two placebo-controlled studies were conducted in 710 patients for the treatment of symptomatic gastroesophageal reflux disease. The most common adverse reactions that were reported as possibly or probably related to Raciper-D (Esomeprazole Magnesium) were diarrhea (4.3%), headache (3.8%), and abdominal pain (3.8%).

6.2 Combination Treatment with Amoxicillin and Clarithromycin

In clinical trials using combination therapy with Raciper-D plus amoxicillin and clarithromycin, no additional adverse reactions specific to these drug combinations were observed. Adverse reactions that occurred were limited to those observed when using Raciper-D (Esomeprazole Magnesium), amoxicillin, or clarithromycin alone.

The most frequently reported drug-related adverse reactions for patients who received triple therapy for 10 days were diarrhea (9.2%), taste perversion (6.6%), and abdominal pain (3.7%). No treatment-emergent adverse reactions were observed at higher rates with triple therapy than were observed with Raciper-D (Esomeprazole Magnesium) alone.

For more information on adverse reactions with amoxicillin or clarithromycin, refer to their package inserts, Adverse Reactions sections.

In clinical trials using combination therapy with Raciper-D (Esomeprazole Magnesium) plus amoxicillin and clarithromycin, no additional increased laboratory abnormalities particular to these drug combinations were observed.

For more information on laboratory changes with amoxicillin or clarithromycin, refer to their package inserts, Adverse Reactions section.

6.3 Postmarketing Experience

The following adverse reactions have been identified during post-approval use of Raciper-D (Esomeprazole Magnesium). Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. These reports are listed below by body system:

Blood And Lymphatic: agranulocytosis, pancytopenia;

Eye: blurred vision;

Gastrointestinal: pancreatitis; stomatitis;

Hepatobiliary: hepatic failure, hepatitis with or without jaundice;

Skin and Subcutaneous Tissue: alopecia, erythema multiforme, hyperhidrosis, photosensitivity, Stevens-Johnson syndrome, toxic epidermal necrolysis (some fatal).

7 DRUG INTERACTIONS


  • May affect plasma levels of antiretroviral drugs – use with atazanavir and nelfinavir is not recommended; if saquinavir is used with Raciper-D, monitor for toxicity and consider saquinavir dose reduction (7.1)


  • May interfere with drugs for which gastric pH affects bioavailability (e.g., ketoconazole, iron salts, and digoxin) (7.2)


  • Combined inhibitor of CYP 2C19 and 3A4 may raise Raciper-D (Esomeprazole Magnesium) levels (7.3)


  • May increase systemic exposure of cilostazol and an active metabolite. Consider dose reduction (7.3)

7.1 Interference with Antiretroviral Therapy

Concomitant use of atazanavir and nelfinavir with proton pump inhibitors is not recommended. Co-administration of atazanavir with proton pump inhibitors is expected to substantially decrease atazanavir plasma concentrations and may result in a loss of therapeutic effect and the development of drug resistance. Co-administration of saquinavir with proton pump inhibitors is expected to increase saquinavir concentrations, which may increase toxicity and require dose reduction.

Omeprazole, of which Raciper-D (Esomeprazole Magnesium) is an enantiomer, has been reported to interact with some antiretroviral drugs. The clinical importance and the mechanisms behind these interactions are not always known. Increased gastric pH during omeprazole treatment may change the absorption of the antiretroviral drug. Other possible interaction mechanisms are via CYP 2C19.

Reduced concentrations of atazanavir and nelfinavir

For some antiretroviral drugs, such as atazanavir and nelfinavir, decreased serum levels have been reported when given together with omeprazole. Following multiple doses of nelfinavir (1250 mg, twice daily) and omeprazole (40 mg daily), AUC was decreased by 36% and 92%, Cmax by 37% and 89% and Cmin by 39% and 75% respectively for nelfinavir and M8. Following multiple doses of atazanavir (400 mg, daily) and omeprazole (40 mg, daily, 2 hr before atazanavir), AUC was decreased by 94%, Cmax by 96%, and Cmin by 95%. Concomitant administration with omeprazole and drugs such as atazanavir and nelfinavir is therefore not recommended.

Increased concentrations of saquinavir

For other antiretroviral drugs, such as saquinavir, elevated serum levels have been reported, with an increase in AUC by 82%, in Cmax by 75%, and in Cmin by 106%, following multiple dosing of saquinavir/ritonavir (1000/100 mg) twice daily for 15 days with omeprazole 40 mg daily co-administered days 11 to 15. Therefore, clinical and laboratory monitoring for saquinavir toxicity is recommended during concurrent use with Raciper-D (Esomeprazole Magnesium). Dose reduction of saquinavir should be considered from the safety perspective for individual patients.

There are also some antiretroviral drugs of which unchanged serum levels have been reported when given with omeprazole.

7.2 Drugs for Which Gastric pH Can Affect Bioavailability

Raciper-D inhibits gastric acid secretion. Therefore, Raciper-D (Esomeprazole Magnesium) may interfere with the absorption of drugs where gastric pH is an important determinant of bioavailability (e.g., ketoconazole, atazanavir, iron salts, and digoxin).

7.3 Effects on Hepatic Metabolism/Cytochrome P-450 Pathways

Raciper-D (Esomeprazole Magnesium) is extensively metabolized in the liver by CYP 2C19 and CYP 3A4. In vitro and in vivo studies have shown that Raciper-D (Esomeprazole Magnesium) is not likely to inhibit CYPs 1A2, 2A6, 2C9, 2D6, 2E1, and 3A4. No clinically relevant interactions with drugs metabolized by these CYP enzymes would be expected. Drug interaction studies have shown that Raciper-D (Esomeprazole Magnesium) does not have any clinically significant interactions with phenytoin, warfarin, quinidine, clarithromycin, or amoxicillin.

However, post-marketing reports of changes in prothrombin measures have been received among patients on concomitant warfarin and Raciper-D (Esomeprazole Magnesium) therapy. Increases in INR and prothrombin time may lead to abnormal bleeding and even death. Patients treated with proton pump inhibitors and warfarin concomitantly may need to be monitored for increases in INR and prothrombin time.

Raciper-D (Esomeprazole Magnesium) may potentially interfere with CYP 2C19, the major Raciper-D (Esomeprazole Magnesium) metabolizing enzyme. Coadministration of Raciper-D (Esomeprazole Magnesium) 30 mg and diazepam, a CYP 2C19 substrate, resulted in a 45% decrease in clearance of diazepam.

Concomitant administration of Raciper-D (Esomeprazole Magnesium) and a combined inhibitor of CYP 2C19 and CYP 3A4, such as voriconazole, may result in more than doubling of the Raciper-D (Esomeprazole Magnesium) exposure. Dose adjustment of Raciper-D (Esomeprazole Magnesium) is not normally required. However, in patients with Zollinger-Ellison’s Syndrome, who may require higher doses up to 240 mg/day, dose adjustment may be considered.

Omeprazole acts as an inhibitor of CYP 2C19. Omeprazole, given in doses of 40 mg daily for one week to 20 healthy subjects in cross-over study, increased Cmax and AUC of cilostazol by 18% and 26% respectively. Cmax and AUC of one of its active metabolites, 3,4-dihydrocilostazol, which has 4-7 times the activity of cilostazol, were increased by 29% and 69% respectively. Co-administration of cilostazol with Raciper-D (Esomeprazole Magnesium) is expected to increase concentrations of cilostazol and its above mentioned active metabolite. Therefore a dose reduction of cilostazol from 100 mg b.i.d. to 50 mg b.i.d. should be considered.

7.4 Combination Therapy with Clarithromycin

Co-administration of Raciper-D (Esomeprazole Magnesium), clarithromycin, and amoxicillin has resulted in increases in the plasma levels of Raciper-D (Esomeprazole Magnesium) and 14-hydroxyclarithromycin [see Clinical Pharmacology (12.4) ].

Concomitant administration of clarithromycin with cisapride, pimozide, astemizole, terfenadine, ergotamine, or dihydroergotamine is contraindicated [see prescribing information for clarithromycin].

8 USE IN SPECIFIC POPULATIONS


  • Severe liver impairment – do not exceed dose of 20 mg

8.1 Pregnancy

Pregnancy Category B

Reproductive studies in rats and rabbits with Raciper-D (Esomeprazole Magnesium) (esomeprazole) and multiple cohort studies in pregnant women with omeprazole use during the first trimester do not show an increased risk of congenital anomalies or adverse pregnancy outcomes. There are, however, no adequate and well controlled studies of Raciper-D (Esomeprazole Magnesium) use in pregnancy. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.

Raciper-D (Esomeprazole Magnesium) is the s-isomer of omeprazole. In four population-based cohort studies that included 1226 women exposed during the first trimester of pregnancy to omeprazole there was no increased risk of congenital anomalies.

Reproductive studies with Raciper-D (Esomeprazole Magnesium) have been performed in rats at doses up to 57 times the human dose and in rabbits at doses up to 35 times the human dose and have revealed no evidence of impaired fertility or harm to the fetus. See Animal Toxicology and/or Pharmacology (13.2).

Reproductive studies conducted with omeprazole on rats at oral doses up to 56 times the human dose and in rabbits at doses up to 56 times the human dose did not show any evidence of teratogenicity. In pregnant rabbits, omeprazole at doses about 5.5 to 56 times the human dose produced dose-related increases in embryo-lethality, fetal resorptions, and pregnancy loss. In rats treated with omeprazole at doses about 5.6 to 56 times the human dose, dose-related embryo/fetal toxicity and postnatal developmental toxicity occurred in offspring.

8.3 Nursing Mothers

Omeprazole concentrations have been measured in breast milk of one woman taking omeprazole 20 mg per day. However, the excretion of Raciper-D in milk has not been studied. It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for tumorigenicity shown for Raciper-D (Esomeprazole Magnesium) in rat carcinogenicity studies, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

8.4 Pediatric Use

The safety and effectiveness of Raciper-D (Esomeprazole Magnesium) have been established in pediatric patients 1 to 17 years of age for short-term treatment (up to eight weeks) of GERD. However, effectiveness has not been demonstrated in patients less than 1 year of age.

1 to 17 years of age

Use of Raciper-D (Esomeprazole Magnesium) in pediatric and adolescent patients 1 to 17 years of age for short-term treatment (up to eight weeks) of GERD is supported by: a) extrapolation of results, already included in the currently approved labeling, from adequate and well-controlled studies that supported the approval of Raciper-D (Esomeprazole Magnesium) for adults, and b) safety and pharmacokinetic studies performed in pediatric and adolescent patients [see Clinical Pharmacology (12.3), Dosage and Administration (2), Adverse Reactions (6.1), and Clinical Studies, (14.3) ]. The safety and effectiveness of Raciper-D (Esomeprazole Magnesium) for other pediatric uses have not been established.

Neonates to less than one year of age

There was no statistically significant difference between Raciper-D (Esomeprazole Magnesium) and placebo in the rate of discontinuation in a multicenter, randomized, double-blind, controlled, treatment-withdrawal study of patients ages 1 to 11 months, inclusive. Patients were enrolled if they had either a clinical diagnosis of suspected GERD, symptomatic GERD, or endoscopically proven GERD. All patients received Raciper-D (Esomeprazole Magnesium) Delayed-Release Oral Suspension once daily during a two-week, open-label phase of the study. There were 80 patients who attained a pre-specified level of symptom improvement and who entered the double-blind phase, in which they were randomized in equal proportions to receive Raciper-D (Esomeprazole Magnesium) or placebo for the next four weeks. Efficacy was assessed by observing the time from randomization to study discontinuation due to symptom worsening during the four-week, treatment-withdrawal phase.

The following pharmacokinetic and pharmacodynamic information was obtained in pediatric patients with GERD aged birth to less than one year of age. In neonates (< 1 month old) given Raciper-D (Esomeprazole Magnesium) 0.5 mg/kg once daily, the percent time with intragastric pH > 4 over the 24-hour dosing period increased from 44% at baseline to 83% on Day 7. In infants (1 to 11 months old, inclusive) given Raciper-D (Esomeprazole Magnesium) 1.0 mg/kg once daily, the percent time with intragastric pH > 4 increased from 29% at baseline to 69% on Day 7, which is similar to the pharmacodynamic effect in adults [see Clinical Pharmacology (12.2)]. Apparent clearance (CL/F) increases with age in pediatric patients from birth to 2 years of age.

Because Raciper-D (Esomeprazole Magnesium) was not shown to be effective in the randomized, placebo-controlled study for this age group, the use of Raciper-D (Esomeprazole Magnesium) in patients less than 1 year of age is not indicated.

8.5 Geriatric Use

Of the total number of patients who received Raciper-D (Esomeprazole Magnesium) in clinical trials, 1459 were 65 to 74 years of age and 354 patients were ≥ 75 years of age.

No overall differences in safety and efficacy were observed between the elderly and younger individuals, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.

10 OVERDOSAGE

A single oral dose of Raciper-D (Esomeprazole Magnesium) at 510 mg/kg (about 103 times the human dose on a body surface area basis), was lethal to rats. The major signs of acute toxicity were reduced motor activity, changes in respiratory frequency, tremor, ataxia, and intermittent clonic convulsions.

The symptoms described in connection with deliberate Raciper-D (Esomeprazole Magnesium) overdose (limited experience of doses in excess of 240 mg/day) are transient. Single doses of 80 mg of Raciper-D (Esomeprazole Magnesium) were uneventful. Reports of overdosage with omeprazole in humans may also be relevant. Doses ranged up to 2,400 mg (120 times the usual recommended clinical dose). Manifestations were variable, but included confusion, drowsiness, blurred vision, tachycardia, nausea, diaphoresis, flushing, headache, dry mouth, and other adverse reactions similar to those seen in normal clinical experience (see omeprazole package insert - Adverse Reactions). No specific antidote for Raciper-D (Esomeprazole Magnesium) is known. Since Raciper-D (Esomeprazole Magnesium) is extensively protein bound, it is not expected to be removed by dialysis. In the event of overdosage, treatment should be symptomatic and supportive.

As with the management of any overdose, the possibility of multiple drug ingestion should be considered. For current information on treatment of any drug overdose contact a Poison Control Center at 1–800–222–1222.

11 DESCRIPTION

The active ingredient in Raciper-D (Esomeprazole Magnesium)® (esomeprazole magnesium) Delayed-Release Capsules and Raciper-D (Esomeprazole Magnesium) (esomeprazole magnesium) For Delayed-Release Oral Suspension is bis(5-methoxy-2-[(S)-[(4-methoxy-3,5-dimethyl-2-pyridinyl)methyl]sulfinyl]-1H-benzimidazole-1-yl) magnesium trihydrate. Raciper-D (Esomeprazole Magnesium) is the S-isomer of omeprazole, which is a mixture of the S- and R- isomers. (Initial U.S. approval of Raciper-D (Esomeprazole Magnesium) magnesium: 2001). Its molecular formula is (C17H18N3O3S)2Mg x 3 H2O with molecular weight of 767.2 as a trihydrate and 713.1 on an anhydrous basis. The structural formula is:

Figure 1

The magnesium salt is a white to slightly colored crystalline powder. It contains 3 moles of water of solvation and is slightly soluble in water. The stability of Raciper-D (Esomeprazole Magnesium) magnesium is a function of pH; it rapidly degrades in acidic media, but it has acceptable stability under alkaline conditions. At pH 6.8 (buffer), the half-life of the magnesium salt is about 19 hours at 25°C and about 8 hours at 37°C.

Raciper-D (Esomeprazole Magnesium) is supplied in delayed-release capsules and in packets for a delayed-release oral suspension. Each delayed-release capsule contains 20 mg, or 40 mg of Raciper-D (Esomeprazole Magnesium) (present as 22.3 mg, or 44.5 mg Raciper-D (Esomeprazole Magnesium) magnesium trihydrate) in the form of enteric-coated granules with the following inactive ingredients: glyceryl monostearate 40-55, hydroxypropyl cellulose, hypromellose, magnesium stearate, methacrylic acid copolymer type C, polysorbate 80, sugar spheres, talc, and triethyl citrate. The capsule shells have the following inactive ingredients: gelatin, FD&C Blue #1, FD&C Red #40, D&C Red #28, titanium dioxide, shellac, ethyl alcohol, isopropyl alcohol, n-butyl alcohol, propylene glycol, sodium hydroxide, polyvinyl pyrrolidone, and D&C Yellow #10.

Each packet of Raciper-D (Esomeprazole Magnesium) For Delayed-Release Oral Suspension contains 10 mg, 20 mg, or 40 mg of Raciper-D (Esomeprazole Magnesium), in the form of the same enteric-coated granules used in Raciper-D (Esomeprazole Magnesium) Delayed-Release Capsules, and also inactive granules. The inactive granules are composed of the following ingredients: dextrose, xanthan gum, crospovidone, citric acid, iron oxide, and hydroxypropyl cellulose. The Raciper-D (Esomeprazole Magnesium) granules and inactive granules are constituted with water to form a suspension and are given by oral, nasogastric, or gastric administration.

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Raciper-D is a proton pump inhibitor that suppresses gastric acid secretion by specific inhibition of the H+/K+-ATPase in the gastric parietal cell. The S- and R-isomers of omeprazole are protonated and converted in the acidic compartment of the parietal cell forming the active inhibitor, the achiral sulphenamide. By acting specifically on the proton pump, Raciper-D (Esomeprazole Magnesium) blocks the final step in acid production, thus reducing gastric acidity. This effect is dose-related up to a daily dose of 20 to 40 mg and leads to inhibition of gastric acid secretion.

12.2 Pharmacodynamics

Antisecretory Activity

The effect of Raciper-D (Esomeprazole Magnesium) on intragastric pH was determined in patients with symptomatic gastroesophageal reflux disease in two separate studies. In the first study of 36 patients, Raciper-D (Esomeprazole Magnesium) 40 mg and 20 mg capsules were administered over 5 days. The results are shown in the following table:

In a second study, the effect on intragastric pH of Raciper-D (Esomeprazole Magnesium) 40 mg administered once daily over a five day period was similar to the first study, (% time with pH > 4 was 68% or 16.3 hours).

Serum Gastrin Effects

The effect of Raciper-D (Esomeprazole Magnesium) on serum gastrin concentrations was evaluated in approximately 2,700 patients in clinical trials up to 8 weeks and in over 1,300 patients for up to 6 to 12 months. The mean fasting gastrin level increased in a dose-related manner. This increase reached a plateau within two to three months of therapy and returned to baseline levels within four weeks after discontinuation of therapy.

Enterochromaffin-like (ECL) Cell Effects

In 24-month carcinogenicity studies of omeprazole in rats, a dose-related significant occurrence of gastric ECL cell carcinoid tumors and ECL cell hyperplasia was observed in both male and female animals [see Nonclinical Toxicology (13.1) ]. Carcinoid tumors have also been observed in rats subjected to fundectomy or long-term treatment with other proton pump inhibitors or high doses of H2-receptor antagonists.

Human gastric biopsy specimens have been obtained from more than 3,000 patients treated with omeprazole in long-term clinical trials. The incidence of ECL cell hyperplasia in these studies increased with time; however, no case of ECL cell carcinoids, dysplasia, or neoplasia has been found in these patients.

In over 1,000 patients treated with Raciper-D (Esomeprazole Magnesium) (10, 20 or 40 mg/day) up to 6 to 12 months, the prevalence of ECL cell hyperplasia increased with time and dose. No patient developed ECL cell carcinoids, dysplasia, or neoplasia in the gastric mucosa.

Endocrine Effects

Raciper-D (Esomeprazole Magnesium) had no effect on thyroid function when given in oral doses of 20 or 40 mg for 4 weeks. Other effects of Raciper-D (Esomeprazole Magnesium) on the endocrine system were assessed using omeprazole studies. Omeprazole given in oral doses of 30 or 40 mg for 2 to 4 weeks had no effect on carbohydrate metabolism, circulating levels of parathyroid hormone, cortisol, estradiol, testosterone, prolactin, cholecystokinin, or secretin.

12.3 Pharmacokinetics

Absorption

Raciper-D Delayed-Release Capsules and Raciper-D (Esomeprazole Magnesium) For Delayed-Release Oral Suspension contain a bioequivalent enteric-coated granule formulation of Raciper-D (Esomeprazole Magnesium) magnesium. Bioequivalency is based on a single dose (40 mg) study in 94 healthy male and female volunteers under fasting condition. After oral administration peak plasma levels (Cmax) occur at approximately 1.5 hours (Tmax). The Cmax increases proportionally when the dose is increased, and there is a three-fold increase in the area under the plasma concentration-time curve (AUC) from 20 to 40 mg. At repeated once-daily dosing with 40 mg, the systemic bioavailability is approximately 90% compared to 64% after a single dose of 40 mg. The mean exposure (AUC) to Raciper-D (Esomeprazole Magnesium) increases from 4.32 µmol*hr/L on Day 1 to 11.2 µmol*hr/L on Day 5 after 40 mg once daily dosing.

The AUC after administration of a single 40 mg dose of Raciper-D (Esomeprazole Magnesium) is decreased by 43% to 53% after food intake compared to fasting conditions. Raciper-D (Esomeprazole Magnesium) should be taken at least one hour before meals.

The pharmacokinetic profile of Raciper-D (Esomeprazole Magnesium) was determined in 36 patients with symptomatic gastroesophageal reflux disease following repeated once daily administration of 20 mg and 40 mg capsules of Raciper-D (Esomeprazole Magnesium) over a period of five days. The results are shown in the following table:

Distribution

Raciper-D (Esomeprazole Magnesium) is 97% bound to plasma proteins. Plasma protein binding is constant over the concentration range of 2 to 20 μmol/L. The apparent volume of distribution at steady state in healthy volunteers is approximately 16 L.

Metabolism

Raciper-D (Esomeprazole Magnesium) is extensively metabolized in the liver by the cytochrome P450 (CYP) enzyme system. The metabolites of Raciper-D (Esomeprazole Magnesium) lack antisecretory activity. The major part of esomeprazole’s metabolism is dependent upon the CYP 2C19 isoenzyme, which forms the hydroxy and desmethyl metabolites. The remaining amount is dependent on CYP 3A4 which forms the sulphone metabolite. CYP 2C19 isoenzyme exhibits polymorphism in the metabolism of Raciper-D (Esomeprazole Magnesium), since some 3% of Caucasians and 15 to 20% of Asians lack CYP 2C19 and are termed Poor Metabolizers. At steady state, the ratio of AUC in Poor Metabolizers to AUC in the rest of the population (Extensive Metabolizers) is approximately 2.

Following administration of equimolar doses, the S- and R-isomers are metabolized differently by the liver, resulting in higher plasma levels of the S- than of the R-isomer.

Excretion

The plasma elimination half-life of Raciper-D (Esomeprazole Magnesium) is approximately 1 to 1.5 hours. Less than 1% of parent drug is excreted in the urine. Approximately 80% of an oral dose of Raciper-D (Esomeprazole Magnesium) is excreted as inactive metabolites in the urine, and the remainder is found as inactive metabolites in the feces.

Pharmacokinetics: Combination Therapy with Antimicrobials

Raciper-D (Esomeprazole Magnesium) magnesium 40 mg once daily was given in combination with clarithromycin 500 mg twice daily and amoxicillin 1000 mg twice daily for 7 days to 17 healthy male and female subjects. The mean steady state AUC and Cmax of Raciper-D (Esomeprazole Magnesium) increased by 70% and 18%, respectively during triple combination therapy compared to treatment with Raciper-D (Esomeprazole Magnesium) alone. The observed increase in Raciper-D (Esomeprazole Magnesium) exposure during co-administration with clarithromycin and amoxicillin is not expected to produce significant safety concerns.

The pharmacokinetic parameters for clarithromycin and amoxicillin were similar during triple combination therapy and administration of each drug alone. However, the mean AUC and Cmax for 14-hydroxyclarithromycin increased by 19% and 22%, respectively, during triple combination therapy compared to treatment with clarithromycin alone. This increase in exposure to 14-hydroxyclarithromycin is not considered to be clinically significant.

Special Populations

Geriatric

The AUC and Cmax values were slightly higher (25% and 18%, respectively) in the elderly as compared to younger subjects at steady state. Dosage adjustment based on age is not necessary.

Pediatric

1 to 11 Years of Age

The pharmacokinetics of Raciper-D (Esomeprazole Magnesium) were studied in pediatric patients with GERD aged 1 to 11 years. Following once daily dosing for 5 days, the total exposure (AUC) for the 10 mg dose in patients aged 6 to 11 years was similar to that seen with the 20 mg dose in adults and adolescents aged 12 to 17 years. The total exposure for the 10 mg dose in patients aged 1 to 5 years was approximately 30% higher than the 10 mg dose in patients aged 6 to 11 years. The total exposure for the 20 mg dose in patients aged 6 to 11 years was higher than that observed with the 20 mg dose in 12 to 17 year-olds and adults, but lower than that observed with the 40 mg dose in 12 to 17 year-olds and adults.

The pharmacokinetics of Raciper-D (Esomeprazole Magnesium) were studied in 28 adolescent patients with GERD aged 12 to 17 years inclusive, in a single center study. Patients were randomized to receive Raciper-D (Esomeprazole Magnesium) 20 mg or 40 mg once daily for 8 days. Mean Cmax and AUC values of Raciper-D (Esomeprazole Magnesium) were not affected by body weight or age; and more than dose-proportional increases in mean Cmax and AUC values were observed between the two dose groups in the study. Overall, Raciper-D (Esomeprazole Magnesium) pharmacokinetics in adolescent patients aged 12 to 17 years were similar to those observed in adult patients with symptomatic GERD.

Gender

The AUC and Cmax values were slightly higher (13%) in females than in males at steady state. Dosage adjustment based on gender is not necessary.

Hepatic Insufficiency

The steady state pharmacokinetics of Raciper-D (Esomeprazole Magnesium) obtained after administration of 40 mg once daily to 4 patients each with mild (Child Pugh A), moderate (Child Pugh Class B), and severe (Child Pugh Class C) liver insufficiency were compared to those obtained in 36 male and female GERD patients with normal liver function. In patients with mild and moderate hepatic insufficiency, the AUCs were within the range that could be expected in patients with normal liver function. In patients with severe hepatic insufficiency the AUCs were 2 to 3 times higher than in the patients with normal liver function. No dosage adjustment is recommended for patients with mild to moderate hepatic insufficiency (Child Pugh Classes A and B). However, in patients with severe hepatic insufficiency (Child Pugh Class C) a dose of 20 mg once daily should not be exceeded [see Dosage and Administration (2)].

Renal Insufficiency

The pharmacokinetics of Raciper-D (Esomeprazole Magnesium) in patients with renal impairment are not expected to be altered relative to healthy volunteers as less than 1% of Raciper-D (Esomeprazole Magnesium) is excreted unchanged in urine.

Other pharmacokinetic observations

Coadministration of oral contraceptives, diazepam, phenytoin, or quinidine did not seem to change the pharmacokinetic profile of Raciper-D (Esomeprazole Magnesium).

Studies evaluating concomitant administration of Raciper-D (Esomeprazole Magnesium) and either naproxen (non-selective NSAID) or rofecoxib (COX-2 selective NSAID) did not identify any clinically relevant changes in the pharmacokinetic profiles of Raciper-D (Esomeprazole Magnesium) or these NSAIDs.

12.4 Microbiology

Raciper-D (Esomeprazole Magnesium), amoxicillin, and clarithromycin triple therapy has been shown to be active against most strains of Helicobacter pylori (H. pylori) in vitro and in clinical infections as described in the Clinical Studies (14) and Indications and Usage (1) sections.

Helicobacter pylori: Susceptibility testing of H. pylori isolates was performed for amoxicillin and clarithromycin using agar dilution methodology, and minimum inhibitory concentrations (MICs) were determined.

Pretreatment Resistance: Clarithromycin pretreatment resistance rate (MIC ≥ 1 mcg/mL) to H. pylori was 15% (66/445) at baseline in all treatment groups combined. A total of > 99% (394/395) of patients had H. pylori isolates that were considered to be susceptible (MIC ≤ 0.25 mcg/mL) to amoxicillin at baseline. One patient had a baseline H. pylori isolate with an amoxicillin MIC = 0.5 mcg/mL.

Clarithromycin Susceptibility Test Results and Clinical/Bacteriologic Outcomes: The baseline H. pylori clarithromycin susceptibility results and the H. pylori eradication results at the Day 38 visit are shown in the table below:

Patients not eradicated of H. pylori following NEXIUM/amoxicillin/clarithromycin triple therapy will likely have clarithromycin resistant H. pylori isolates. Therefore, clarithromycin susceptibility testing should be done, when possible. Patients with clarithromycin resistant H. pylori should not be re-treated with a clarithromycin-containing regimen.

Amoxicillin Susceptibility Test Results and Clinical/Bacteriological Outcomes:

In the NEXIUM/amoxicillin/clarithromycin clinical trials, 83% (176/212) of the patients in the NEXIUM/amoxicillin/clarithromycin treatment group who had pretreatment amoxicillin susceptible MICs (≤ 0.25 mcg/mL) were eradicated of H. pylori, and 17% (36/212) were not eradicated of H. pylori. Of the 36 patients who were not eradicated of H. pylori on triple therapy, 16 had no post-treatment susceptibility test results and 20 had post-treatment H. pylori isolates with amoxicillin susceptible MICs. Fifteen of the patients who were not eradicated of H. pylori on triple therapy also had post-treatment H. pylori isolates with clarithromycin resistant MICs. There were no patients with H. pylori isolates who developed treatment emergent resistance to amoxicillin.

Susceptibility Test for Helicobacter pylori: The reference methodology for susceptibility testing of H. pylori is agar dilution MICs. One to three microliters of an inoculum equivalent to a No. 2 McFarland standard (1 x 107 - 1 x 108 CFU/mL for H. pylori) are inoculated directly onto freshly prepared antimicrobial containing Mueller-Hinton agar plates with 5% aged defibrinated sheep blood (≥ 2 weeks old). The agar dilution plates are incubated at 35°C in a microaerobic environment produced by a gas generating system suitable for Campylobacter. After 3 days of incubation, the MICs are recorded as the lowest concentration of antimicrobial agent required to inhibit growth of the organism. The clarithromycin and amoxicillin MIC values should be interpreted according to the following criteria:

Effects on Gastrointestinal Microbial Ecology: Decreased gastric acidity due to any means, including proton pump inhibitors, increases gastric counts of bacteria normally present in the gastrointestinal tract. Treatment with proton pump inhibitors may lead to slightly increased risk of gastrointestinal infections such as Salmonella and Campylobacter and possibly Clostridium difficile in hospitalized patients.

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

The carcinogenic potential of Raciper-D was assessed using studies of omeprazole, of which Raciper-D (Esomeprazole Magnesium) is an enantiomer. In two 24-month oral carcinogenicity studies in rats, omeprazole at daily doses of 1.7, 3.4, 13.8, 44, and 141 mg/kg/day (about 0.7 to 57 times the human dose of 20 mg/day expressed on a body surface area basis) produced gastric ECL cell carcinoids in a dose-related manner in both male and female rats; the incidence of this effect was markedly higher in female rats, which had higher blood levels of omeprazole. Gastric carcinoids seldom occur in the untreated rat. In addition, ECL cell hyperplasia was present in all treated groups of both sexes. In one of these studies, female rats were treated with 13.8 mg omeprazole/kg/day (about 5.6 times the human dose on a body surface area basis) for 1 year, then followed for an additional year without the drug. No carcinoids were seen in these rats. An increased incidence of treatment-related ECL cell hyperplasia was observed at the end of 1 year (94% treated vs. 10% controls). By the second year the difference between treated and control rats was much smaller (46% vs. 26%) but still showed more hyperplasia in the treated group. Gastric adenocarcinoma was seen in one rat (2%). No similar tumor was seen in male or female rats treated for 2 years. For this strain of rat no similar tumor has been noted historically, but a finding involving only one tumor is difficult to interpret. A 78-week mouse carcinogenicity study of omeprazole did not show increased tumor occurrence, but the study was not conclusive.

Raciper-D (Esomeprazole Magnesium) was negative in the Ames mutation test, in the in vivo rat bone marrow cell chromosome aberration test, and the in vivo mouse micronucleus test. Raciper-D (Esomeprazole Magnesium), however, was positive in the in vitro human lymphocyte chromosome aberration test. Omeprazole was positive in the in vitro human lymphocyte chromosome aberration test, the in vivo mouse bone marrow cell chromosome aberration test, and the in vivo mouse micronucleus test.

The potential effects of Raciper-D (Esomeprazole Magnesium) on fertility and reproductive performance were assessed using omeprazole studies. Omeprazole at oral doses up to 138 mg/kg/day in rats (about 56 times the human dose on a body surface area basis) was found to have no effect on reproductive performance of parental animals.

13.2 Animal Toxicology and/or Pharmacology

Reproductive Toxicology Studies

Reproductive studies have been performed in rats at oral doses up to 280 mg/kg/day (about 57 times the human dose on a body surface area basis) and in rabbits at oral doses up to 86 mg/kg/day (about 35 times the human dose on a body surface area basis) and have revealed no evidence of impaired fertility or harm to the fetus due to Raciper-D (Esomeprazole Magnesium).

Reproductive studies conducted with omeprazole in rats at oral doses up to 138 mg/kg/day (about 56 times the human dose on a body surface area basis) and in rabbits at doses up to 69 mg/kg/day (about 56 times the human dose on a body surface area basis) did not disclose any evidence for a teratogenic potential of omeprazole. In rabbits, omeprazole in a dose range of 6.9 to 69.1 mg/kg/day (about 5.5 to 56 times the human dose on a body surface area basis) produced dose-related increases in embryo-lethality, fetal resorptions, and pregnancy disruptions. In rats, dose-related embryo/fetal toxicity and postnatal developmental toxicity were observed in offspring resulting from parents treated with omeprazole at 13.8 to 138.0 mg/kg/day (about 5.6 to 56 times the human dose on a body surface area basis).

In these four studies, the range of median days to the start of sustained resolution (defined as 7 consecutive days with no heartburn) was 5 days for Raciper-D (Esomeprazole Magnesium) 40 mg, 7 to 8 days for Raciper-D (Esomeprazole Magnesium) 20 mg and 7 to 9 days for omeprazole 20 mg.

There are no comparisons of 40 mg of Raciper-D (Esomeprazole Magnesium) with 40 mg of omeprazole in clinical trials assessing either healing or symptomatic relief of erosive esophagitis.

Long-Term Maintenance of Healing of Erosive Esophagitis

Two multicenter, randomized, double-blind placebo-controlled 4-arm trials were conducted in patients with endoscopically confirmed, healed erosive esophagitis to evaluate Raciper-D (Esomeprazole Magnesium) 40 mg (n=174), 20 mg (n=180), 10 mg (n=168) or placebo (n=171) once daily over six months of treatment.

No additional clinical benefit was seen with Raciper-D (Esomeprazole Magnesium) 40 mg over Raciper-D (Esomeprazole Magnesium) 20 mg.

The percentages of patients that maintained healing of erosive esophagitis at the various time points are shown in the figures below:

Figure 2

Patients remained in remission significantly longer and the number of recurrences of erosive esophagitis was significantly less in patients treated with Raciper-D (Esomeprazole Magnesium) compared to placebo.

In both studies, the proportion of patients on Raciper-D (Esomeprazole Magnesium) who remained in remission and were free of heartburn and other GERD symptoms was well differentiated from placebo.

In a third multicenter open label study of 808 patients treated for 12 months with Raciper-D (Esomeprazole Magnesium) 40 mg, the percentage of patients that maintained healing of erosive esophagitis was 93.7% for six months and 89.4% for one year.

14.2 Symptomatic Gastroesophageal Reflux Disease (GERD)

Two multicenter, randomized, double-blind, placebo-controlled studies were conducted in a total of 717 patients comparing four weeks of treatment with Raciper-D (Esomeprazole Magnesium) 20 mg or 40 mg once daily versus placebo for resolution of GERD symptoms. Patients had ≥ 6-month history of heartburn episodes, no erosive esophagitis by endoscopy, and heartburn on at least four of the seven days immediately preceding randomization.

The percentage of patients that were symptom-free of heartburn was significantly higher in the Raciper-D (Esomeprazole Magnesium) groups compared to placebo at all follow-up visits (Weeks 1, 2, and 4).

No additional clinical benefit was seen with Raciper-D (Esomeprazole Magnesium) 40 mg over Raciper-D (Esomeprazole Magnesium) 20 mg.

The percent of patients symptom-free of heartburn by day are shown in the figures below:

14.3 Pediatric Gastroesophageal Reflux Disease

1 to 11 Years of Age

In a multicenter, parallel-group study, 109 pediatric patients with a history of endoscopically-proven GERD (1 to 11 years of age; 53 female; 89 Caucasian, 19 Black, 1 Other) were treated with Raciper-D (Esomeprazole Magnesium) once daily for up to 8 weeks to evaluate safety and tolerability. Dosing by patient weight was as follows:

weight < 20 kg: once daily treatment with Raciper-D (Esomeprazole Magnesium) 5 mg or 10 mg

weight ≥ 20 kg: once daily treatment with Raciper-D (Esomeprazole Magnesium) 10 mg or 20 mg

Patients were endoscopically characterized as to the presence or absence of erosive esophagitis.

Of the 109 patients, 53 had erosive esophagitis at baseline (51 had mild, 1 moderate, and 1 severe esophagitis). Although most of the patients who had a follow up endoscopy at the end of 8 weeks of treatment healed, spontaneous healing cannot be ruled out because these patients had low grade erosive esophagitis prior to treatment, and the trial did not include a concomitant control.

12 to 17 Years of Age

In a multicenter, randomized, double-blind, parallel-group study, 149 adolescent patients (12 to 17 years of age; 89 female; 124 Caucasian, 15 Black, 10 Other) with clinically diagnosed GERD were treated with either Raciper-D (Esomeprazole Magnesium) 20 mg or Raciper-D (Esomeprazole Magnesium) 40 mg once daily for up to 8 weeks to evaluate safety and tolerability. Patients were not endoscopically characterized as to the presence or absence of erosive esophagitis.

14.4 Risk Reduction of NSAID-Associated Gastric Ulcer

Two multicenter, double-blind, placebo-controlled studies were conducted in patients at risk of developing gastric and/or duodenal ulcers associated with continuous use of non-selective and COX-2 selective NSAIDs. A total of 1429 patients were randomized across the 2 studies. Patients ranged in age from 19 to 89 with 70.7% female, 29.3% male, 82.9% Caucasian, 5.5% Black, 3.7% Asian, and 8.0% Others. At baseline, the patients in these studies were endoscopically confirmed not to have ulcers but were determined to be at risk for ulcer occurrence due to their age (≥60 years) and/or history of a documented gastric or duodenal ulcer within the past 5 years. Patients receiving NSAIDs and treated with Raciper-D (Esomeprazole Magnesium) 20 mg or 40 mg once-a-day experienced significant reduction in gastric ulcer occurrences relative to placebo treatment at 26 weeks. No additional benefit was seen with Raciper-D (Esomeprazole Magnesium) 40 mg over Raciper-D (Esomeprazole Magnesium) 20 mg. These studies did not demonstrate significant reduction in the development of NSAID-associated duodenal ulcer due to the low incidence.

14.5 Helicobacter pylori (H.pylori) Eradication in Patients with Duodenal Ulcer Disease

Triple Therapy (NEXIUM/amoxicillin/clarithromycin): Two multicenter, randomized, double-blind studies were conducted using a 10 day treatment regimen. The first study (191) compared Raciper-D (Esomeprazole Magnesium) 40 mg once daily in combination with amoxicillin 1000 mg twice daily and clarithromycin 500 mg twice daily to Raciper-D (Esomeprazole Magnesium) 40 mg once daily plus clarithromycin 500 mg twice daily. The second study (193) compared Raciper-D (Esomeprazole Magnesium) 40 mg once daily in combination with amoxicillin 1000 mg twice daily and clarithromycin 500 mg twice daily to Raciper-D (Esomeprazole Magnesium) 40 mg once daily. H. pylori eradication rates, defined as at least two negative tests and no positive tests from CLOtest®, histology and/or culture, at 4 weeks post-therapy were significantly higher in the Raciper-D (Esomeprazole Magnesium) plus amoxicillin and clarithromycin group than in the Raciper-D (Esomeprazole Magnesium) plus clarithromycin or Raciper-D (Esomeprazole Magnesium) alone group. The results are shown in the following table:

The percentage of patients with a healed baseline duodenal ulcer by 4 weeks after the 10 day treatment regimen in the Raciper-D (Esomeprazole Magnesium) plus amoxicillin and clarithromycin group was 75% (n=156) and 57% (n=60) respectively, in the 191 and 193 studies (per-protocol analysis).

14.6 Pathological Hypersecretory Conditions Including Zollinger-Ellison Syndrome

In a multicenter, open-label dose-escalation study of 21 patients (15 males and 6 females, 18 Caucasian and 3 Black, mean age of 55.5 years) with pathological hypersecretory conditions, such as Zollinger-Ellison Syndrome, Raciper-D (Esomeprazole Magnesium) significantly inhibited gastric acid secretion. Initial dose was 40 mg twice daily in 19/21 patients and 80 mg twice daily in 2/21 patients. Total daily doses ranging from 80 mg to 240 mg for 12 months maintained gastric acid output below the target levels of 10 mEq/h in patients without prior gastric acid-reducing surgery and below 5 mEq/hr in patients with prior gastric acid-reducing surgery. At the Month 12 final visit, 18/20 (90%) patients had Basal Acid Output (BAO) under satisfactory control (median BAO = 0.17 mmol/hr). Of the 18 patients evaluated with a starting dose of 40 mg twice daily, 13 (72%) had their BAO controlled with the original dosing regimen at the final visit.

WHAT IS Raciper-D (Esomeprazole Magnesium)?

Raciper-D (Esomeprazole Magnesium) is a prescription medicine called a proton pump inhibitor (PPI).

Raciper-D (Esomeprazole Magnesium) is used in adults:

- for 4 to 8 weeks to treat the symptoms of gastroesophageal reflux disease (GERD). Raciper-D (Esomeprazole Magnesium) may also be prescribed to heal acid-related damage to the lining of the esophagus (erosive esophagitis), and to help continue this healing.

GERD is a chronic condition (lasts a long time) that occurs when acid from the stomach backs up into the esophagus (food pipe) causing symptoms, such as heartburn, or damage to the lining of the esophagus. Common symptoms include frequent heartburn that will not go away, a sour or bitter taste in the mouth, and difficulty swallowing.

- for up to 6 months to reduce the risk of stomach ulcers in some people taking pain medicines called non-steroidal anti-inflammatory drugs (NSAIDs).

- to treat patients with a stomach infection (Helicobacter pylori), along with the antibiotics amoxicillin and clarithromycin.

- for the long-term treatment of Zollinger-Ellison Syndrome. Zollinger-Ellison Syndrome is a rare condition in which the stomach produces a more than normal amount of acid.

For children and adolescents 1 to 17 years of age, Raciper-D (Esomeprazole Magnesium) may be prescribed for up to 8 weeks for short-term treatment of GERD.
