DRUGS & SUPPLEMENTS
Lap Plus usesLap Plus consists of Hydrochlorothiazide, Losartan Potassium.
Lap Plus information
Lap Plus (Hydrochlorothiazide) is an antihypertensive, diuretic drug that acts on the electrolyte reabsorption in the renal tubular mechanism increasing the excretion of chloride and sodium in equivalent amounts. The exact mechanism of its antihypertensive action is not known at this time.
Lap Plus indications
Lap Plus (Hydrochlorothiazide) is typically employed for the treatment of patients suffering from hypertension, either as monotherapy or in combination with other antihypertensive medication. It is also employed in some cases as a diuretic agent. Lap Plus (Hydrochlorothiazide) therapy may also be prescribed for the treatment of hepatic cirrhosis, edema (in patients suffering from congestive heart failure), nephrotic syndrome, drug induced edema, chronic renal failure or acute glomerulonephritis. Health care professionals may prescribe this drug in order to treat other medical conditions as well; if you would like to know more about the reasons you have been prescribed this drug, it is advised to ask your personal physician.
Lap Plus warnings
Lap Plus (Hydrochlorothiazide) may not be used in the treatment of patients who are allergic to this drug, any of its components or other sulfonamide-derived medication. Also, this drug may not be suitable for use in patients that are suffering from anuria, azotemia or impaired renal functions. Caution should be employed if the patient is suffering from hepatic disease. Other medical conditions may also influence the examining health care provider's decision of prescribing Lap Plus (Hydrochlorothiazide); it is strongly recommended to make sure that the health care professional is fully aware of your health condition and medical history before starting a treatment with this drug.
Use of Lap Plus (Hydrochlorothiazide) during pregnancy or breast-feeding is also not recommended. This medicine may affect an unborn baby and it also passes into breast milk. As such, use of this drug in pregnant women or breast-feeding mothers should not be employed.
Lap Plus intake guidelines
You should always take Lap Plus (Hydrochlorothiazide) as you have been directed by the prescribing health care specialist. While in some cases daily administration of the drug is recommended, other patients may be prescribed an intermittent therapy. Also, the number of daily doses may vary. As such, it is best that you do not follow another patient's intake schedule. If you have difficulties understanding the intake guidelines that your prescribing health care professional has provided, you should ask for further explanations from an authorized health care specialist - such as a pharmacist, a doctor or a nurse.
Lap Plus dosage
The exact Lap Plus (Hydrochlorothiazide) dosage may vary greatly from one case to another, depending on the condition being treated, on the patient's medical history and general health condition, on his or her age as well as on a number of other factors. As such you are advised to use the exact Lap Plus (Hydrochlorothiazide) dosage that has been prescribed to you and never use the dosage prescribed to another patient or a dosage that you have been prescribed in the past. Taking a different Lap Plus (Hydrochlorothiazide) dose may cause the treatment to not have the desired effect, and if you take this drug in larger doses you may have a higher risk of developing side effects, or you may suffer from an overdose.
Lap Plus overdose
You should never exceed the Lap Plus (Hydrochlorothiazide) prescribed dosage, in order to avoid an overdose with this medication. However, if you consider that you are affected by an overdose with this drug it is advised to immediately consult your personal health care provider, the local poisons center or to go to the nearest medical facility to seek emergency medical attention. The common symptoms of an overdose with Lap Plus (Hydrochlorothiazide) are dehydration and cardiac arrhythmia. The patient may also suffer from electrolyte depletion and thus may present the relevant signs and symptoms.
Lap Plus missed dose
In case you have missed a dose of Lap Plus (Hydrochlorothiazide), it is advised that you take the dose as soon as you remember. If the moment when you remember is too close to another intake of the medication, you should completely skip the missed Lap Plus (Hydrochlorothiazide) dose and take the next scheduled dose on time. You should never take a larger dose of the drug in order to make up for a missed dose, unless your prescribing health care provider directs you to do so.
Lap Plus side effects
In some patients Lap Plus (Hydrochlorothiazide) may cause side effects. While they are not very common, it is recommended to let your personal health care provider know if you begin experiencing any side effects. Several types of symptoms are possible: dizziness, headache, paresthesias, gastric irritation, anorexia, nausea and vomiting, diarrhea or constipation, pancreatitis, jaundice, hypotension. Metabolic side effects may include glycosuria, hyperglycemia, hyperuricemia, hypokalemia or hyponatremia. Renal failure or dysfunction may develop, as well as interstitial nephritis. Some patients reported experiencing muscle spasms, restlessness, unusual weakness and blurred vision. In some cases photosensitivity, anaphylactic reactions, respiratory distress, fever, rashes, vasculitis or toxic epidermal necrolysis have occurred.
Lap Plus drug reactions
Lap Plus (Hydrochlorothiazide) may interact with barbiturates and narcotics, as well as with alcohol. If you are also following a treatment course with antidiabetic drugs, their dosage may need to be adjusted before starting to take Lap Plus (Hydrochlorothiazide). This drug may have an additive effect with other antihypertensive medication. ACE inhibitors, ACTH, corticosteroids and skeletal muscle relaxants may also interact with this drug causing unwanted effects. This drug may not be properly absorbed if the patient is also taking Colestipol resins or Cholestyramine. NSAIDs, lithium and Pressor amines may affect or be affected by Lap Plus (Hydrochlorothiazide), and as such it is strongly recommended to let the prescribing health care provider know if you are taking these or any other drugs before starting a therapy course with this medicine. Other drug interactions that are not listed here are also possible.
INDICATIONS AND USAGE
Lap Plus Tablets, USP is indicated for the treatment of hypertension. It may be used alone or in combination with other antihypertensive agents, including diuretics.
Hypertensive Patients with Left Ventricular Hypertrophy
Lap Plus (Losartan Potassium) Tablets USP is indicated to reduce the risk of stroke in patients with hypertension and left ventricular hypertrophy, but there is evidence that this benefit does not apply to Black patients. (See PRECAUTIONS , Race and CLINICAL PHARMACOLOGY , Pharmacodynamics and Clinical Effects, Reduction in the Risk of Stroke, Race .)
Nephropathy in Type 2 Diabetic Patients
Lap Plus (Losartan Potassium) is indicated for the treatment of diabetic nephropathy with an elevated serum creatinine and proteinuria (urinary albumin to creatinine ratio ≥ 300 mg/g) in patients with type 2 diabetes and a history of hypertension. In this population, Lap Plus (Losartan Potassium) reduces the rate of progression of nephropathy as measured by the occurrence of doubling of serum creatinine or end stage renal disease (need for dialysis or renal transplantation) (see CLINICAL PHARMACOLOGY , Pharmacodynamics and Clinical Effects ).
Lap Plus (Losartan Potassium) Tablets USP is contraindicated in patients who are hypersensitive to any component of this product.
Fetal/Neonatal Morbidity and Mortality
Drugs that act directly on the renin-angiotensin system can cause fetal and neonatal morbidity and death when administered to pregnant women. Several dozen cases have been reported in the world literature in patients who were taking angiotensin converting enzyme inhibitors. When pregnancy is detected, Lap Plus tablets should be discontinued as soon as possible.
The use of drugs that act directly on the renin-angiotensin system during the second and third trimesters of pregnancy has been associated with fetal and neonatal injury, including hypotension, neonatal skull hypoplasia, anuria, reversible or irreversible renal failure, and death. Oligohydramnios has also been reported, presumably resulting from decreased fetal renal function; oligohydramnios in this setting has been associated with fetal limb contractures, craniofacial deformation, and hypoplastic lung development. Prematurity, intrauterine growth retardation, and patent ductus arteriosus have also been reported, although it is not clear whether these occurrences were due to exposure to the drug.
These adverse effects do not appear to have resulted from intrauterine drug exposure that has been limited to the first trimester.
Mothers whose embryos and fetuses are exposed to an angiotensin II receptor antagonist only during the first trimester should be so informed. Nonetheless, when patients become pregnant, physicians should have the patient discontinue the use of Lap Plus (Losartan Potassium) tablets as soon as possible.
Rarely (probably less often than once in every thousand pregnancies), no alternative to an angiotensin II receptor antagonist will be found. In these rare cases, the mothers should be apprised of the potential hazards to their fetuses, and serial ultrasound examinations should be performed to assess the intra-amniotic environment.
If oligohydramnios is observed, Lap Plus (Losartan Potassium) tablets should be discontinued unless it is considered life-saving for the mother. Contraction stress testing (CST), a non-stress test (NST), or biophysical profiling (BPP) may be appropriate, depending upon the week of pregnancy. Patients and physicians should be aware, however, that oligohydramnios may not appear until after the fetus has sustained irreversible injury.
Infants with histories of in utero exposure to an angiotensin II receptor antagonist should be closely observed for hypotension, oliguria, and hyperkalemia. If oliguria occurs, attention should be directed toward support of blood pressure and renal perfusion. Exchange transfusion or dialysis may be required as means of reversing hypotension and/or substituting for disordered renal function.
Lap Plus (Losartan Potassium) has been shown to produce adverse effects in rat fetuses and neonates, including decreased body weight, delayed physical and behavioral development, mortality and renal toxicity. With the exception of neonatal weight gain (which was affected at doses as low as 10 mg/kg/day), doses associated with these effects exceeded 25 mg/kg/day (approximately three times the maximum recommended human dose of 100 mg on a mg/m2 basis). These findings are attributed to drug exposure in late gestation and during lactation. Significant levels of losartan and its active metabolite were shown to be present in rat fetal plasma during late gestation and in rat milk.
Hypotension - Volume-Depleted Patients
In patients who are intravascularly volume-depleted (e.g., those treated with diuretics), symptomatic hypotension may occur after initiation of therapy with Lap Plus (Losartan Potassium). These conditions should be corrected prior to administration of Lap Plus (Losartan Potassium) tablets, or a lower starting dose should be used (see DOSAGE AND ADMINISTRATION ).
See ADVERSE REACTIONS , Post-Marketing Experience.
Impaired Hepatic Function
Based on pharmacokinetic data which demonstrate significantly increased plasma concentrations of losartan in cirrhotic patients, a lower dose should be considered for patients with impaired liver function.
Impaired Renal Function
As a consequence of inhibiting the renin-angiotensin-aldosterone system, changes in renal function have been reported in susceptible individuals treated with Lap Plus (Losartan Potassium); in some patients, these changes in renal function were reversible upon discontinuation of therapy.
In patients whose renal function may depend on the activity of the renin-angiotensin-aldosterone system (e.g., patients with severe congestive heart failure), treatment with angiotensin converting enzyme inhibitors has been associated with oliguria and/or progressive azotemia and (rarely) with acute renal failure and/or death. Similar outcomes have been reported with Lap Plus (Losartan Potassium).
In studies of ACE inhibitors in patients with unilateral or bilateral renal artery stenosis, increases in serum creatinine or blood urea nitrogen (BUN) have been reported. Similar effects have been reported with Lap Plus (Losartan Potassium); in some patients, these effects were reversible upon discontinuation of therapy.
Electrolyte imbalances are common in patients with renal impairment, with or without diabetes, and should be addressed. In a clinical study conducted in type 2 diabetic patients with proteinuria, the incidence of hyperkalemia was higher in the group treated with Lap Plus as compared to the placebo group; however, few patients discontinued therapy due to hyperkalemia (see ADVERSE REACTIONS ).
Information for Patients
Pregnancy: Female patients of childbearing age should be told about the consequences of second-and third-trimester exposure to drugs that act on the renin-angiotensin system, and they should also be told that these consequences do not appear to have resulted from intrauterine drug exposure that has been limited to the first trimester. These patients should be asked to report pregnancies to their physicians as soon as possible.
Potassium Supplements: A patient receiving Lap Plus (Losartan Potassium) tablets should be told not to use potassium supplements or salt substitutes containing potassium without consulting the prescribing physician (see PRECAUTIONS , Drug Interactions ).
Drug Interactions: No significant drug-drug pharmacokinetic interactions have been found in interaction studies with hydrochlorothiazide, digoxin, warfarin, cimetidine and phenobarbital. Rifampin, an inducer of drug metabolism, decreased the concentrations of losartan and its active metabolite. (See CLINICAL PHARMACOLOGY , Drug Interactions .) In humans, two inhibitors of P450 3A4 have been studied. Ketoconazole did not affect the conversion of losartan to the active metabolite after intravenous administration of losartan, and erythromycin had no clinically significant effect after oral administration. Fluconazole, an inhibitor of P450 2C9, decreased active metabolite concentration and increased losartan concentration. The pharmacodynamic consequences of concomitant use of losartan and inhibitors of P450 2C9 have not been examined. Subjects who do not metabolize losartan to active metabolite have been shown to have a specific, rare defect in cytochrome P450 2C9. These data suggest that the conversion of losartan to its active metabolite is mediated primarily by P450 2C9 and not P450 3A4.
As with other drugs that block angiotensin II or its effects, concomitant use of potassium-sparing diuretics (e.g., spironolactone, triamterene, amiloride), potassium supplements, or salt substitutes containing potassium may lead to increases in serum potassium.
Lithium: As with other drugs which affect the excretion of sodium, lithium excretion may be reduced. Therefore, serum lithium levels should be monitored carefully if lithium salts are to be co-administered with angiotensin II receptor antagonists.
Non-Steroidal Anti-Inflammatory Drugs (NSAIDS) including Selective Cyclooxygenase-2 Inhibitors(COX-2Inhibitors): In patients who are elderly, volume-depleted (including those on diuretic therapy), or with compromised renal function co-administration of NSAIDS, including selective COX-2 inhibitors, with angiotensin II receptor antagonists (including losartan) may result in deterioration of renal function, including possible acute renal failure. These effects are usually reversible. Monitor renal function periodically in patients receiving losartan and NSAID therapy.
The antihypertensive effect of angiotensin II receptor antagonists, including losartan may be attenuated by NSAIDs, including selective COX-2 inhibitors.
Dual blockade of the renin-angiotensin-aldosterone system: Dual blockade of the renin-angiotensin-aldosterone system is associated with increased risk of hypotension, syncope, hyperkalemia, and changes in renal function (including acute renal failure). Closely monitor blood pressure, renal function, and electrolytes in patients on Lap Plus (Losartan Potassium) Tablets and ACE inhibitors.
Carcinogenesis, Mutagenesis, Impairment of Fertility
Lap Plus was not carcinogenic when administered at maximally tolerated dosages to rats and mice for 105 and 92 weeks, respectively. Female rats given the highest dose (270 mg/kg/day) had a slightly higher incidence of pancreatic acinar adenoma. The maximally tolerated dosages (270 mg/kg/day in rats, 200 mg/kg/day in mice) provided systemic exposures for losartan and its pharmacologically active metabolite that were approximately 160- and 90-times (rats) and 30- and 15-times (mice) the exposure of a 50 kg human given 100 mg per day.
Lap Plus (Losartan Potassium) was negative in the microbial mutagenesis and V-79 mammalian cell mutagenesis assays and in the in vitro alkaline elution and in vitro and in vivo chromosomal aberration assays. In addition, the active metabolite showed no evidence of genotoxicity in the microbial mutagenesis, in vitro alkaline elution, and in vitro chromosomal aberration assays.
Fertility and reproductive performance were not affected in studies with male rats given oral doses of Lap Plus (Losartan Potassium) up to approximately 150 mg/kg/day. The administration of toxic dosage levels in females (300/200 mg/kg/day) was associated with a significant (p<0.05) decrease in the number of corpora lutea/female, implants/female, and live fetuses/female at C-section. At 100 mg/kg/day only a decrease in the number of corpora lutea/female was observed. The relationship of these findings to drug-treatment is uncertain since there was no effect at these dosage levels on implants/pregnant female, percent post-implantation loss, or live animals/litter at parturition. In nonpregnant rats dosed at 135 mg/kg/day for 7 days, systemic exposure (AUCs) for losartan and its active metabolite were approximately 66 and 26 times the exposure achieved in man at the maximum recommended human daily dosage (100 mg).
Pregnancy Categories C (first trimester) and D (second and third trimesters). See WARNING , Fetal/Neonatal Morbidity and Mortality .
It is not known whether losartan is excreted in human milk, but significant levels of losartan and its active metabolite were shown to be present in rat milk. Because of the potential for adverse effects on the nursing infant, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.
Antihypertensive effects of Lap Plus have been established in hypertensive pediatric patients aged 6 to 16 years. There are no data on the effect of Lap Plus (Losartan Potassium) on blood pressure in pediatric patients under the age of 6 or in pediatric patients with glomerular filtration rate <30 mL/min/1.73 m2 (see CLINICAL PHARMACOLOGY , Pharmacokinetics, Special Populations and Pharmacodynamics and Clinical Effects and DOSAGE AND ADMINISTRATION).
Of the total number of patients receiving Lap Plus (Losartan Potassium) in controlled clinical studies for hypertension, 391 patients (19%) were 65 years and over, while 37 patients (2%) were 75 years and over. In a controlled clinical study for renal protection in type 2 diabetic patients with proteinuria, 248 patients (33%) were 65 years and over. In a controlled clinical study for the reduction in the combined risk of cardiovascular death, stroke and myocardial infarction in hypertensive patients with left ventricular hypertrophy, 2857 patients (62%) were 65 years and over, while 808 patients (18%) were 75 years and over. No overall differences in effectiveness or safety were observed between these patients and younger patients, but greater sensitivity of some older individuals cannot be ruled out.
In the LIFE study, Black patients with hypertension and left ventricular hypertrophy had a lower risk of stroke on atenolol than on Lap Plus (Losartan Potassium). Given the difficulty in interpreting subset differences in large trials, it cannot be known whether the observed difference is the result of chance. However, the LIFE study does not provide evidence that the benefits of Lap Plus (Losartan Potassium) on reducing the risk of cardiovascular events in hypertensive patients with left ventricular hypertrophy apply to Black patients. (See CLINICAL PHARMACOLOGY , Pharmacodynamics and Clinical Effects ; Reduction in the Risk of Stroke .)
Lap Plus has been evaluated for safety in more than 3300 adult patients treated for essential hypertension and 4058 patients/subjects overall. Over 1200 patients were treated for over 6 months and more than 800 for over one year. In general, treatment with Lap Plus (Losartan Potassium) was well-tolerated. The overall incidence of adverse experiences reported with Lap Plus (Losartan Potassium) was similar to placebo.
In controlled clinical trials, discontinuation of therapy due to clinical adverse experiences was required in 2.3 percent of patients treated with Lap Plus (Losartan Potassium) and 3.7 percent of patients given placebo.
The following table of adverse events is based on four 6- to 12-week, placebo-controlled trials involving over 1000 patients on various doses (10-150 mg) of losartan and over 300 patients given placebo. All doses of losartan are grouped because none of the adverse events appeared to have a dose-related frequency. The adverse experiences reported in ≥1% of patients treated with Lap Plus (Losartan Potassium) and more commonly than placebo are shown in the table below.
The following adverse events were also reported at a rate of 1% or greater in patients treated with losartan, but were as, or more frequent, in the placebo group: asthenia/fatigue, edema/swelling, abdominal pain, chest pain, nausea, headache, pharyngitis, diarrhea, dyspepsia, myalgia, insomnia, cough, sinus disorder.
Adverse events occurred at about the same rates in men and women, older and younger patients, and Black and non-Black patients.
A patient with known hypersensitivity to aspirin and penicillin, when treated with Lap Plus (Losartan Potassium), was withdrawn from study due to swelling of the lips and eyelids and facial rash, reported as angioedema, which returned to normal 5 days after therapy was discontinued.
Superficial peeling of palms and hemolysis were reported in one subject.
In addition to the adverse events above, potentially important events that occurred in at least two patients/subjects exposed to losartan or other adverse events that occurred in <1% of patients in clinical studies are listed below. It cannot be determined whether these events were causally related to losartan: Body as a Whole: facial edema, fever, orthostatic effects, syncope; Cardiovascular: angina pectoris, second degree AV block, CVA, hypotension, myocardial infarction, arrhythmias including atrial fibrillation, palpitation, sinus bradycardia, tachycardia, ventricular tachycardia, ventricular fibrillation; Digestive: anorexia, constipation, dental pain, dry mouth, flatulence, gastritis, vomiting; Hematologic: anemia; Metabolic: gout; Musculoskeletal: arm pain, hip pain, joint swelling, knee pain, musculoskeletal pain, shoulder pain, stiffness, arthralgia, arthritis, fibromyalgia, muscle weakness; Nervous System/Psychiatric: anxiety, anxiety disorder, ataxia, confusion, depression, dream abnormality, hypesthesia, decreased libido, memory impairment, migraine, nervousness, paresthesia, peripheral neuropathy, panic disorder, sleep disorder, somnolence, tremor, vertigo; Respiratory: dyspnea, bronchitis, pharyngeal discomfort, epistaxis, rhinitis, respiratory congestion; Skin: alopecia, dermatitis, dry skin, ecchymosis, erythema, flushing, photosensitivity, pruritus, rash, sweating, urticaria; Special Senses: blurred vision, burning/stinging in the eye, conjunctivitis, taste perversion, tinnitus, decrease in visual acuity; Urogenital: impotence, nocturia, urinary frequency, urinary tract infection.
Persistent dry cough (with an incidence of a few percent) has been associated with ACE-inhibitor use and in practice can be a cause of discontinuation of ACE-inhibitor therapy. Two prospective, parallel-group, double-blind, randomized, controlled trials were conducted to assess the effects of losartan on the incidence of cough in hypertensive patients who had experienced cough while receiving ACE-inhibitor therapy. Patients who had typical ACE-inhibitor cough when challenged with lisinopril, whose cough disappeared on placebo, were randomized to losartan 50 mg, lisinopril 20 mg, or either placebo (one study, n=97) or 25 mg hydrochlorothiazide (n=135). The double-blind treatment period lasted up to 8 weeks. The incidence of cough is shown below.
† Demographics = (89% caucasian, 64% female)
†† Demographics = (90% caucasian, 51% female)
These studies demonstrate that the incidence of cough associated with losartan therapy, in a population that all had cough associated with ACE-inhibitor therapy, is similar to that associated with hydrochlorothiazide or placebo therapy.
Cases of cough, including positive re-challenges, have been reported with the use of losartan in post-marketing experience.
Pediatric Patients: No relevant differences between the adverse experience profile for pediatric patients and that previously reported for adult patients were identified.
Hypertensive Patients with Left Ventricular Hypertrophy
In the LIFE study, adverse events with Lap Plus (Losartan Potassium) were similar to those reported previously for patients with hypertension.
Nephropathy in Type 2 Diabetic Patients
In the RENAAL study involving 1513 patients treated with Lap Plus tablets or placebo, the overall incidences of reported adverse experiences were similar for the two groups. Lap Plus (Losartan Potassium) tablets was generally well tolerated as evidenced by a similar incidence of discontinuations due to side effects compared to placebo (19% for Lap Plus (Losartan Potassium) tablets, 24% for placebo). The adverse experiences, regardless of drug relationship, reported with an incidence of ≥4% of patients treated with Lap Plus (Losartan Potassium) tablets and occurring more commonly than placebo, on a background of conventional antihypertensive therapy, are shown in the table below.
The following additional adverse reactions have been reported in post-marketing experience:
Digestive: Hepatitis (reported rarely).
General Disorders and Administration Site Conditions : Malaise.
Hemic: Thrombocytopenia (reported rarely).
Hypersensitivity: Angioedema, including swelling of the larynx and glottis, causing airway obstruction and/or swelling of the face, lips, pharynx, and/or tongue has been reported rarely in patients treated with losartan; some of these patients previously experienced angioedema with other drugs including ACE inhibitors. Vasculitis, including Henoch-Schönlein purpura, has been reported. Anaphylactic reactions have been reported.
Metabolic and Nutrition: Hyperkalemia, hyponatremia have been reported with losartan.
Musculoskeletal: Rare cases of rhabdomyolysis have been reported in patients receiving angiotensin II receptor blockers.
Nervous system disorders: Dysgeusia
Respiratory: Dry cough.
Laboratory Test Findings
In controlled clinical trials, clinically important changes in standard laboratory parameters were rarely associated with administration of Lap Plus (Losartan Potassium).
Creatinine, Blood Urea Nitrogen: Minor increases in blood urea nitrogen (BUN) or serum creatinine were observed in less than 0.1 percent of patients with essential hypertension treated with Lap Plus (Losartan Potassium) alone (see PRECAUTIONS , Impaired Renal Function ).
Hemoglobin and Hematocrit: Small decreases in hemoglobin and hematocrit (mean decreases of approximately 0.11 grams percent and 0.09 volume percent, respectively) occurred frequently in patients treated with Lap Plus (Losartan Potassium) alone, but were rarely of clinical importance. No patients were discontinued due to anemia.
Liver Function Tests: Occasional elevations of liver enzymes and/or serum bilirubin have occurred. In patients with essential hypertension treated with Lap Plus (Losartan Potassium) alone, one patient (<0.1%) was discontinued due to these laboratory adverse experiences.
Significant lethality was observed in mice and rats after oral administration of 1000 mg/kg and 2000 mg/kg, respectively, about 44 and 170 times the maximum recommended human dose on a mg/m2 basis.
Limited data are available in regard to overdosage in humans. The most likely manifestation of overdosage would be hypotension and tachycardia; bradycardia could occur from parasympathetic (vagal) stimulation. If symptomatic hypotension should occur, supportive treatment should be instituted.
Neither losartan nor its active metabolite can be removed by hemodialysis.
DOSAGE AND ADMINISTRATION
Adult Hypertensive Patients
Lap Plus tablets may be administered with other antihypertensive agents, and with or without food.
Dosing must be individualized. The usual starting dose of Lap Plus (Losartan Potassium) tablets is 50 mg once daily, with 25 mg used in patients with possible depletion of intravascular volume (e.g., patients treated with diuretics) (see WARNINGS , Hypotension - Volume-Depleted Patients ) and patients with a history of hepatic impairment (see PRECAUTIONS , General ). Lap Plus (Losartan Potassium) tablets can be administered once or twice daily with total daily doses ranging from 25 mg to 100 mg.
If the antihypertensive effect measured at trough using once-a-day dosing is inadequate, a twice-a-day regimen at the same total daily dose or an increase in dose may give a more satisfactory response. The effect of losartan is substantially present within one week but in some studies the maximal effect occurred in 3-6 weeks (see CLINICAL PHARMACOLOGY , Pharmacodynamics and Clinical Effects, Hypertension).
If blood pressure is not controlled by Lap Plus (Losartan Potassium) alone, a low dose of a diuretic may be added. Hydrochlorothiazide has been shown to have an additive effect (see CLINICAL PHARMACOLOGY , Pharmacodynamics and Clinical Effects, Hypertension ).
No initial dosage adjustment is necessary for elderly patients or for patients with renal impairment, including patients on dialysis.
Pediatric Hypertensive Patients ≥ 6 years of age
The usual recommended starting dose is 0.7 mg/kg once daily (up to 50 mg total) administered as a tablet or a suspension (see Preparation of Suspension). Dosage should be adjusted according to blood pressure response. Doses above 1.4 mg/kg (or in excess of 100 mg) daily have not been studied in pediatric patients. (See CLINICAL PHARMACOLOGY , Pharmacokinetics, Special Populations and Pharmacodynamics and Clinical Effects , and WARNINGS , Hypotension - Volume-Depleted Patients .)
Lap Plus (Losartan Potassium) is not recommended in pediatric patients <6 years of age or in pediatric patients with glomerular filtration rate <30 mL/min/1.73 m2 (see CLINICAL PHARMACOLOGY , Pharmacokinetics, Special Populations and Pharmacodynamics and Clinical Effects , and PRECAUTIONS ).
Preparation of Suspension
Add 10 mL of Purified Water USP to an 8 ounce (240 mL) amber polyethylene terephthalate (PET) bottle containing ten 50 mg Lap Plus (Losartan Potassium) tablets. Immediately shake for at least 2 minutes. Let the concentrate stand for 1 hour and then shake for 1 minute to disperse the tablet contents. Separately prepare a 50/50 volumetric mixture of Ora-Plus ** and Ora-Sweet SF **. Add 190 mL of the 50/50 Ora-Plus /Ora-Sweet SF mixture to the tablet and water slurry in the PET bottle and shake for 1 minute to disperse the ingredients. The suspension should be refrigerated at 2-8°C (36-46°F) and can be stored for up to 4 weeks. Shake the suspension prior to each use and return promptly to the refrigerator.
Hypertensive Patients with Left Ventricular Hypertrophy
The usual starting dose is 50 mg of Lap Plus (Losartan Potassium) tablets once daily. Hydrochlorothiazide 12.5 mg daily should be added and/or the dose of Lap Plus (Losartan Potassium) should be increased to 100 mg once daily followed by an increase in hydrochlorothiazide to 25 mg once daily based on blood pressure response (see CLINICAL PHARMACOLOGY , Pharmacodynamics and Clinical Effects, Reduction in the Risk of Stroke ).
Nephropathy in Type 2 Diabetic Patients
The usual starting dose is 50 mg once daily. The dose should be increased to 100 mg once daily based on blood pressure response (see CLINICAL PHARMACOLOGY, Pharmacodynamics and Clinical Effects, Nephropathy in Type 2 Diabetic Patients). Lap Plus (Losartan Potassium) may be administered with insulin and other commonly used hypoglycemic agents (e.g., sulfonylureas, glitazones and glucosidase inhibitors).

What is the most important information I should know about Lap Plus (Losartan Potassium) Tablets?
Do not take Lap Plus (Losartan Potassium) Tablets if you are pregnant or plan to become pregnant. Lap Plus (Losartan Potassium) Tablets can harm your unborn baby causing injury and even death. Stop taking Lap Plus (Losartan Potassium) Tablets if you become pregnant and call your doctor right away. If you plan to become pregnant, talk to your doctor about other treatment options before taking Lap Plus (Losartan Potassium) Tablets.
What is Lap Plus Tablets?
Lap Plus (Losartan Potassium) Tablets is a prescription medicine called an angiotensin receptor blocker (ARB). It is used:
