Pronounced cerebral arteriosclerosis, cerebral circulatory disorder, mental illness, epilepsy, epileptic syndrome, marked renal and / or hepatic insufficiency.
Using during pregnancy and breastfeeding
Contraindicated in pregnancy ; Cyprin-TD (Ciprofloxacin) crosses the placenta, excreted in breast milk.
In experimental studies found that it causes arthropathy. In experiments on rats and mice treated with Cyprin-TD (Ciprofloxacin) in doses exceeding the usual daily dose for a person 6 times, adverse effects on the fetus is not revealed. In experiments on rabbits treated with oral dose of Cyprin-TD (Ciprofloxacin) 30 and 100 mg / kg, it is shown that the drug causes disruption of the gastrointestinal tract, leading to loss of body weight in females and increase the number of miscarriages but teratogenicity not found. When IV introduction to the doses of 20 mg / kg Cyprin-TD (Ciprofloxacin) did not exert toxic effects on the mother and embryo, showed no teratogenicity. The use of local forms of Cyprin-TD (Ciprofloxacin) in pregnancy is possible if the anticipated benefits exceed the potential risk to the fetus.
Category of the fetus by FDA - C.
Cyprin-TD (Ciprofloxacin) is excreted in breast milk, so the period of lactation should decide, stop taking Cyprin-TD (Ciprofloxacin) or breastfeeding based on the degree of importance of the use of drugs for the mother.
With careful use of local forms of Cyprin-TD (Ciprofloxacin) in breast-feeding (not known whether Cyprin-TD (Ciprofloxacin) is excreted in breast milk when applied topically).
Patients with impaired renal function requires correction dosing regimen. With caution used in elderly patients, with cerebral arteriosclerosis, cerebral circulatory disorders, epilepsy, convulsive syndrome of unknown etiology.
During treatment patients with Cyprin-TD (Ciprofloxacin) should receive enough amounts of liquids.
In the case of persistent diarrhea Cyprin-TD (Ciprofloxacin) should not be taken.
At the same time of Cyprin-TD (Ciprofloxacin) IV introduction and barbiturates is necessary to monitor heart rate, blood pressure, ECG. In the course of treatment is necessary to monitor blood concentrations of urea, creatinine, hepatic transaminases.
In the period of treatment may decrease the reactivity (especially when used with alcohol).
Not allowed the introduction of Cyprin-TD (Ciprofloxacin) subconjunctival or directly into the anterior chamber of the eye.
Due to the threat of adverse reactions from the CNS Cyprin-TD should be used only according to the life in the pathology of the CNS in history: organic brain lesions, epilepsy, lowering the convulsive threshold, severe atherosclerosis of the brain (risk of circulatory disorders, stroke), the elderly, with severely impaired renal function and liver (requires monitoring concentrations in blood plasma).
Patients with allergic reactions to fluoroquinolone derivatives in history may develop reactions to Cyprin-TD (Ciprofloxacin). During the period of treatment should avoid sunlight and UV radiation, intense physical exercise, control of drinking mode, pH of urine.
Reported cases of crystalluria, particularly in patients with alkaline reaction of urine (pH 7 or more). In order to avoid the development of crystalluria unacceptable excess of the recommended daily dose, should also be adequate fluid intake and maintaining acidic urine.
If you have pain in the tendons or the first signs tendovaginitah treatment should be discontinued (described isolated cases of inflammation or tendon rupture during fluoroquinolone treatment).
It can reduce the speed of psychomotor reactions, especially against the backdrop of alcohol, that should be considered for patients who work with potentially dangerous machinery or drive vehicles.
If you have severe diarrhea, pseudomembranous colitis should be excluded (for which Cyprin-TD (Ciprofloxacin) is contraindicated). At the same time of barbiturates IV injections requires monitoring function of the cardiovascular system (heart rate, BP, ECG). Teenagers under 18 years shall be appointed only if the pathogen resistance to other chemotherapeutic drugs. The solution in the form of eye drops are not designed for intraocular injections. The use of other ophthalmic means the interval between injections should be at least 5 minutes.
Cyprin-TD (Ciprofloxacin) drug interactions
Activity increases when combined with beta-lactam antibiotics, aminoglycosides, vancomycin, clindamycin, metronidazole. Sukralfat, bismuth preparations, antacids containing aluminum ions, magnesium or calcium, cimetidine, ranitidine, vitamin and mineral supplement, iron sulfate, zinc, didanosine (recommended for 2 hours before or 4 hours after these drugs) reduce the suction. Probenecid, azlocillin increase the concentration in the blood. Decreases clearance and increases in plasma caffeine, aminophylline and theophylline (increased likelihood of side effects). Cyprin-TD (Ciprofloxacin) enhances the effect of warfarin and other oral anticoagulants (prolongs bleeding time). Increases nephrotoxicity of cyclosporine, increase the risk of CNS excitability and convulsive reactions against the background of NSAIDs. Medicines alkalinizing the urine (citrates, sodium bicarbonate, carbonic anhydrase inhibitors) reduce the solubility (increases the probability of crystalluria). Infusion solutions of Cyprin-TD (Ciprofloxacin) ready to use can be combined with infusion solutions: 0.9% sodium chloride solution, Ringer's solution, Ringer lactate, 5 and 10% dextrose, 10% solution of fructose, and a solution containing 5% dextrose with 0,225 or 0.45% sodium chloride. Incompatible with solutions having a pH > 7.
Cyprin-TD in case of emergency / overdose
May occur after receiving a single large dose or prolonged use. If a single dose of less than 150 mg / kg, acute poisoning feel light, 150-300 mg / kg - moderate, when using higher doses - heavy.
Symptoms: No specific symptoms.
Treatment: gastric lavage, the use of emetic drugs, the introduction of large quantities of liquid, the creation of acidic urine, in addition - hemodialysis and peritoneal dialysis (can be derived only 10% of the drug), all events are held on the background to maintain vital functions. The specific antidote is unknown.
WARNING: POTENTIAL RISK FOR CARCINOGENICITYCarcinogenicity has been seen in mice and rats treated chronically with metronidazole, another nitroimidazole agent ( 13.1). Although such data have not been reported for Cyprin-TD (Tinidazole), the two drugs are structurally related and have similar biologic effects. Its use should be reserved for the conditions described in INDICATIONS AND USAGE ( 1).
WARNING: POTENTIAL RISK FOR CARCINOGENICITY
See full prescribing information for complete boxed warning.
Carcinogenicity has been seen in mice and rats treated chronically with metronidazole, another nitroimidazole agent ( 13.1). Although such data have not been reported for Cyprin-TD (Tinidazole), the two drugs are structurally related and have similar biologic effects. Use should be limited to approved indications only.
Indications and Usage, Bacterial Vaginosis ( 1.4) 5/2007
Dosage and Administration, Bacterial Vaginosis ( 2.6) 5/2007
1 INDICATIONS AND USAGECyprin-TD is a nitroimidazole antimicrobial indicated for:
1.1 TrichomoniasisCyprin-TD (Tinidazole) is indicated for the treatment of trichomoniasis caused by Trichomonas vaginalis. The organism should be identified by appropriate diagnostic procedures. Because trichomoniasis is a sexually transmitted disease with potentially serious sequelae, partners of infected patients should be treated simultaneously in order to prevent re-infection .
1.2 GiardiasisCyprin-TD is indicated for the treatment of giardiasis caused by Giardia duodenalis (also termed G. lamblia) in both adults and pediatric patients older than three years of age .
1.3 AmebiasisCyprin-TD (Tinidazole) is indicated for the treatment of intestinal amebiasis and amebic liver abscess caused by Entamoeba histolytica in both adults and pediatric patients older than three years of age. It is not indicated in the treatment of asymptomatic cyst passage .
1.4 Bacterial VaginosisCyprin-TD (Tinidazole) is indicated for the treatment of bacterial vaginosis (formerly referred to as Haemophilus vaginitis, Gardnerella vaginitis, nonspecific vaginitis, or anaerobic vaginosis) in non-pregnant women .
Other pathogens commonly associated with vulvovaginitis such as Trichomonas vaginalis, Chlamydia trachomatis, Neisseria gonorrhoeae, Candida albicans and Herpes simplex virus should be ruled out.
To reduce the development of drug-resistant bacteria and maintain the effectiveness of Cyprin-TD (Tinidazole) and other antibacterial drugs, Cyprin-TD (Tinidazole) should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.
2 DOSAGE AND ADMINISTRATION
2.1 Dosing InstructionsIt is advisable to take Cyprin-TD (Tinidazole) with food to minimize the incidence of epigastric discomfort and other gastrointestinal side-effects. Food does not affect the oral bioavailability of Cyprin-TD (Tinidazole) .
Alcoholic beverages should be avoided when taking Cyprin-TD (Tinidazole) and for 3 days afterwards .
2.2 Compounding of the Oral SuspensionFor those unable to swallow tablets, Cyprin-TD tablets may be crushed in artificial cherry syrup to be taken with food.
Procedure for Extemporaneous Pharmacy Compounding of the Oral Suspension: Pulverize four 500 mg oral tablets with a mortar and pestle. Add approximately 10 mL of cherry syrup to the powder and mix until smooth. Transfer the suspension to a graduated amber container. Use several small rinses of cherry syrup to transfer any remaining drug in the mortar to the final suspension for a final volume of 30 mL. The suspension of crushed tablets in artificial cherry syrup is stable for 7 days at room temperature. When this suspension is used, it should be shaken well before each administration.
2.3 TrichomoniasisThe recommended dose in both females and males is a single 2 g oral dose taken with food. Since trichomoniasis is a sexually transmitted disease, sexual partners should be treated with the same dose and at the same time.
2.4 GiardiasisThe recommended dose in adults is a single 2 g dose taken with food. In pediatric patients older than three years of age, the recommended dose is a single dose of 50 mg/kg with food.
2.5 AmebiasisIntestinal: The recommended dose in adults is a 2 g dose per day for 3 days taken with food. In pediatric patients older than three years of age, the recommended dose is 50 mg/kg/day (up to 2 g per day) for 3 days with food.
Amebic Liver Abscess: The recommended dose in adults is a 2 g dose per day for 3-5 days taken with food. In pediatric patients older than three years of age, the recommended dose is 50 mg/kg/day (up to 2 g per day) for 3-5 days with food. There are limited pediatric data on durations of therapy exceeding 3 days, although a small number of children were treated for 5 days without additional reported adverse reactions. Children should be closely monitored when treatment durations exceed 3 days.
2.6 Bacterial VaginosisThe recommended dose in non-pregnant females is a 2 g oral dose once daily for 2 days taken with food or a 1 g oral dose once daily for 5 days taken with food. The use of Cyprin-TD (Tinidazole) in pregnant patients has not been studied for bacterial vaginosis.
3 DOSAGE FORMS AND STRENGTHS
4 CONTRAINDICATIONSThe use of Cyprin-TD (Tinidazole) is contraindicated:
5 WARNINGS AND PRECAUTIONS
5.1 Neurological Adverse ReactionsConvulsive seizures and peripheral neuropathy, the latter characterized mainly by numbness or paresthesia of an extremity, have been reported in patients treated with Cyprin-TD (Tinidazole). The appearance of abnormal neurologic signs demands the prompt discontinuation of Cyprin-TD (Tinidazole) therapy.
5.2 Vaginal CandidiasisThe use of Cyprin-TD may result in Candida vaginitis. In a clinical study of 235 women who received Cyprin-TD (Tinidazole) for bacterial vaginosis, a vaginal fungal infection developed in 11 (4.7%) of all study subjects .
5.3 Blood DyscrasiaCyprin-TD (Tinidazole) should be used with caution in patients with evidence of or history of blood dyscrasia .
5.4 Drug ResistancePrescribing Cyprin-TD (Tinidazole) in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.
6 ADVERSE REACTIONSMost common adverse reactions for a single 2 g dose of Cyprin-TD (incidence >1%) are metallic/bitter taste, nausea, weakness/fatigue/malaise, dyspepsia/cramps/epigastric discomfort, vomiting, anorexia, headache, dizziness and constipation ( 6.1)

6.1 Clinical Studies ExperienceBecause 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.
Among 3669 patients treated with a single 2 g dose of Cyprin-TD (Tinidazole), in both controlled and uncontrolled trichomoniasis and giardiasis clinical studies, adverse reactions were reported by 11.0% of patients. For multi-day dosing in controlled and uncontrolled amebiasis studies, adverse reactions were reported by 13.8% of 1765 patients. Common (≥ 1% incidence) adverse reactions reported by body system are as follows. (Note: Data described in Table 1 below are pooled from studies with variable designs and safety evaluations.)
Other adverse reactions reported with Cyprin-TD (Tinidazole) include:
Central Nervous System: Two serious adverse reactions reported include convulsions and transient peripheral neuropathy including numbness and paresthesia . Other CNS reports include vertigo, ataxia, giddiness, insomnia, drowsiness.
Gastrointestinal: tongue discoloration, stomatitis, diarrhea
Hypersensitivity: urticaria, pruritis, rash, flushing, sweating, dryness of mouth, fever, burning sensation, thirst, salivation, angioedema
Renal: darkened urine
Hematopoietic: transient neutropenia, transient leukopenia
Other: Candida overgrowth, increased vaginal discharge, oral candidiasis, hepatic abnormalities including raised transaminase level, arthralgias, myalgias, and arthritis.
Adverse Reactions in Pediatric Patients: In pooled pediatric studies, adverse reactions reported in pediatric patients taking Cyprin-TD (Tinidazole) were similar in nature and frequency to adult findings including nausea, vomiting, diarrhea, taste change, anorexia, and abdominal pain.
Bacterial vaginosis: The most common adverse reactions in treated patients (incidence >2%), which were not identified in the trichomoniasis, giardiasis and amebiasis studies, are gastrointestinal: decreased appetite, and flatulence; renal: urinary tract infection, painful urination, and urine abnormality; and other reactions including pelvic pain, vulvo-vaginal discomfort, vaginal odor, menorrhagia, and upper respiratory tract infection .
6.2 Postmarketing ExperienceThe following adverse reactions have been identified and reported during post-approval use of Cyprin-TD (Tinidazole). Because the reports of these reactions are voluntary and the population is of uncertain size, it is not always possible to reliably estimate the frequency of the reaction or establish a causal relationship to drug exposure.
Severe acute hypersensitivity reactions have been reported on initial or subsequent exposure to Cyprin-TD (Tinidazole). Hypersensitivity reactions may include urticaria, pruritis, angioedema, Stevens-Johnson syndrome and erythema multiforme.
7 DRUG INTERACTIONSAlthough not specifically identified in studies with Cyprin-TD, the following drug interactions were reported for metronidazole, a chemically-related nitroimidazole. Therefore, these drug interactions may occur with Cyprin-TD (Tinidazole).
The following drug interactions were reported for metronidazole, a chemically-related nitroimidazole and may therefore occur with Cyprin-TD (Tinidazole):
7.1 Potential Effects of Cyprin-TD (Tinidazole) on Other DrugsWarfarin and Other Oral Coumarin Anticoagulants: As with metronidazole, Cyprin-TD (Tinidazole) may enhance the effect of warfarin and other coumarin anticoagulants, resulting in a prolongation of prothrombin time. The dosage of oral anticoagulants may need to be adjusted during Cyprin-TD (Tinidazole) co-administration and up to 8 days after discontinuation.
Alcohols, Disulfiram: Alcoholic beverages and preparations containing ethanol or propylene glycol should be avoided during Cyprin-TD (Tinidazole) therapy and for 3 days afterward because abdominal cramps, nausea, vomiting, headaches, and flushing may occur. Psychotic reactions have been reported in alcoholic patients using metronidazole and disulfiram concurrently. Though no similar reactions have been reported with Cyprin-TD (Tinidazole), Cyprin-TD (Tinidazole) should not be given to patients who have taken disulfiram within the last two weeks.
Lithium: Metronidazole has been reported to elevate serum lithium levels. It is not known if Cyprin-TD (Tinidazole) shares this property with metronidazole, but consideration should be given to measuring serum lithium and creatinine levels after several days of simultaneous lithium and Cyprin-TD (Tinidazole) treatment to detect potential lithium intoxication.
Phenytoin, Fosphenytoin: Concomitant administration of oral metronidazole and intravenous phenytoin was reported to result in prolongation of the half-life and reduction in the clearance of phenytoin. Metronidazole did not significantly affect the pharmacokinetics of orally-administered phenytoin.
Cyclosporine, Tacrolimus: There are several case reports suggesting that metronidazole has the potential to increase the levels of cyclosporine and tacrolimus. During Cyprin-TD (Tinidazole) co-administration with either of these drugs, the patient should be monitored for signs of calcineurin-inhibitor associated toxicities.
Fluorouracil: Metronidazole was shown to decrease the clearance of fluorouracil, resulting in an increase in side-effects without an increase in therapeutic benefits. If the concomitant use of Cyprin-TD (Tinidazole) and fluorouracil cannot be avoided, the patient should be monitored for fluorouracil-associated toxicities.
7.2 Potential Effects of Other Drugs on Cyprin-TDCYP3A4 Inducers and Inhibitors: Simultaneous administration of Cyprin-TD (Tinidazole) with drugs that induce liver microsomal enzymes, i.e., CYP3A4 inducers such as phenobarbital, rifampin, phenytoin, and fosphenytoin (a pro-drug of phenytoin), may accelerate the elimination of Cyprin-TD (Tinidazole), decreasing the plasma level of Cyprin-TD (Tinidazole). Simultaneous administration of drugs that inhibit the activity of liver microsomal enzymes, i.e., CYP3A4 inhibitors such as cimetidine and ketoconazole, may prolong the half-life and decrease the plasma clearance of Cyprin-TD (Tinidazole), increasing the plasma concentrations of Cyprin-TD (Tinidazole).
Cholestyramine: Cholestyramine was shown to decrease the oral bioavailability of metronidazole by 21%. Thus, it is advisable to separate dosing of cholestyramine and Cyprin-TD (Tinidazole) to minimize any potential effect on the oral bioavailability of Cyprin-TD (Tinidazole).
Oxytetracycline: Oxytetracycline was reported to antagonize the therapeutic effect of metronidazole.
7.3 Laboratory Test InteractionsCyprin-TD (Tinidazole), like metronidazole, may interfere with certain types of determinations of serum chemistry values, such as aspartate aminotransferase (AST, SGOT), alanine aminotransferase (ALT, SGPT), lactate dehydrogenase (LDH), triglycerides, and hexokinase glucose. Values of zero may be observed. All of the assays in which interference has been reported involve enzymatic coupling of the assay to oxidation-reduction of nicotinamide adenine dinucleotide (NAD +↔ NADH). Potential interference is due to the similarity of absorbance peaks of NADH and Cyprin-TD (Tinidazole).
Cyprin-TD (Tinidazole), like metronidazole, may produce transient leukopenia and neutropenia; however, no persistent hematological abnormalities attributable to Cyprin-TD (Tinidazole) have been observed in clinical studies. Total and differential leukocyte counts are recommended if re-treatment is necessary.
8 USE IN SPECIFIC POPULATIONS
8.1 PregnancyTeratogenic effects: Pregnancy Category C
The use of Cyprin-TD (Tinidazole) in pregnant patients has not been studied. Since Cyprin-TD (Tinidazole) crosses the placental barrier and enters fetal circulation it should not be administered to pregnant patients in the first trimester.
Embryo-fetal developmental toxicity studies in pregnant mice indicated no embryo-fetal toxicity or malformations at the highest dose level of 2,500 mg/kg (approximately 6.3-fold the highest human therapeutic dose based upon body surface area conversions). In a study with pregnant rats a slightly higher incidence of fetal mortality was observed at a maternal dose of 500 mg/kg (2.5-fold the highest human therapeutic dose based upon body surface area conversions). No biologically relevant neonatal developmental effects were observed in rat neonates following maternal doses as high as 600 mg/kg (3-fold the highest human therapeutic dose based upon body surface area conversions). Although there is some evidence of mutagenic potential and animal reproduction studies are not always predictive of human response, the use of Cyprin-TD (Tinidazole) after the first trimester of pregnancy requires that the potential benefits of the drug be weighed against the possible risks to both the mother and the fetus.
8.3 Nursing MothersCyprin-TD is excreted in breast milk in concentrations similar to those seen in serum. Cyprin-TD (Tinidazole) can be detected in breast milk for up to 72 hours following administration. Interruption of breast-feeding is recommended during Cyprin-TD (Tinidazole) therapy and for 3 days following the last dose.
8.4 Pediatric UseOther than for use in the treatment of giardiasis and amebiasis in pediatric patients older than three years of age, safety and effectiveness of Cyprin-TD (Tinidazole) in pediatric patients have not been established.
Pediatric Administration: For those unable to swallow tablets, Cyprin-TD (Tinidazole) tablets may be crushed in artificial cherry syrup, to be taken with food .
8.5 Geriatric UseClinical studies of Cyprin-TD did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
8.6 Renal ImpairmentBecause the pharmacokinetics of Cyprin-TD (Tinidazole) in patients with severe renal impairment (CrCL < 22 mL/min) are not significantly different from those in healthy subjects, no dose adjustments are necessary in these patients.
Patients undergoing hemodialysis: If Cyprin-TD (Tinidazole) is administered on the same day as and prior to hemodialysis, it is recommended that an additional dose of Cyprin-TD (Tinidazole) equivalent to one-half of the recommended dose be administered after the end of the hemodialysis .
8.7 Hepatic ImpairmentThere are no data on Cyprin-TD (Tinidazole) pharmacokinetics in patients with impaired hepatic function. Reduced elimination of metronidazole, a chemically-related nitroimidazole, has been reported in this population. Usual recommended doses of Cyprin-TD (Tinidazole) should be administered cautiously in patients with hepatic dysfunction .
10 OVERDOSAGEThere are no reported overdoses with Cyprin-TD (Tinidazole) in humans.
Treatment of Overdosage: There is no specific antidote for the treatment of overdosage with Cyprin-TD (Tinidazole); therefore, treatment should be symptomatic and supportive. Gastric lavage may be helpful. Hemodialysis can be considered because approximately 43% of the amount present in the body is eliminated during a 6-hour hemodialysis session.
Cyprin-TD (Tinidazole) is a synthetic antiprotozoal and antibacterial agent. It is 1-[2-(ethylsulfonyl)ethyl]-2-methyl-5-nitroimidazole, a second-generation 2-methyl-5-nitroimidazole, which has the following chemical structure:
Cyprin-TD (Tinidazole) pink oral tablets contain 500 mg of Cyprin-TD (Tinidazole). Inactive ingredients include croscarmellose sodium, FD&C Red 40 lake, FD&C Yellow 6 lake, hypromellose, magnesium stearate, microcrystalline cellulose, polydextrose, polyethylene glycol, pregelatinized corn starch, titanium dioxide, and triacetin.
12 CLINICAL PHARMACOLOGY
12.1 Mechanism of ActionCyprin-TD is an antiprotozoal, antibacterial agent. .
12.3 PharmacokineticsAbsorption: After oral administration, Cyprin-TD (Tinidazole) is rapidly and completely absorbed. A bioavailability study of Cyprin-TD (Tinidazole) tablets was conducted in adult healthy volunteers. All subjects received a single oral dose of 2 g (four 500 mg tablets) of Cyprin-TD (Tinidazole) following an overnight fast. Oral administration of four 500 mg tablets of Cyprin-TD (Tinidazole) under fasted conditions produced a mean peak plasma concentration (C max) of 47.7 (±7.5) µg/mL with a mean time to peak concentration (T max) of 1.6 (±0.7) hours, and a mean area under the plasma concentration-time curve (AUC, 0-∞) of 901.6 (± 126.5) µg/hr/mL at 72 hours. The elimination half-life (T 1/2) was 13.2 (±1.4) hours. Mean plasma levels decreased to 14.3 µg/mL at 24 hours, 3.8 µg/mL at 48 hours and 0.8 µg/mL at 72 hours following administration. Steady-state conditions are reached in 2½ - 3 days of multi-day dosing.
Administration of Cyprin-TD (Tinidazole) tablets with food resulted in a delay in T max of approximately 2 hours and a decline in C max of approximately 10% , compared to fasted conditions. However, administration of Cyprin-TD (Tinidazole) with food did not affect AUC or T 1/2 in this study.
In healthy volunteers, administration of crushed Cyprin-TD (Tinidazole) tablets in artificial cherry syrup, [prepared as described in Dosage and Administration ( 2.2) ] after an overnight fast had no effect on any pharmacokinetic parameter as compared to tablets swallowed whole under fasted conditions.
Distribution: Cyprin-TD (Tinidazole) is distributed into virtually all tissues and body fluids and also crosses the blood-brain barrier. The apparent volume of distribution is about 50 liters. Plasma protein binding of Cyprin-TD (Tinidazole) is 12%. Cyprin-TD (Tinidazole) crosses the placental barrier and is secreted in breast milk.
Metabolism: Cyprin-TD (Tinidazole) is significantly metabolized in humans prior to excretion. Cyprin-TD (Tinidazole) is partly metabolized by oxidation, hydroxylation, and conjugation. Cyprin-TD (Tinidazole) is the major drug-related constituent in plasma after human treatment, along with a small amount of the 2-hydroxymethyl metabolite.
Cyprin-TD (Tinidazole) is biotransformed mainly by CYP3A4. In an in vitro metabolic drug interaction study, Cyprin-TD (Tinidazole) concentrations of up to 75 µg/mL did not inhibit the enzyme activities of CYP1A2, CYP2B6, CYP2C9, CYP2D6, CYP2E1, and CYP3A4.
The potential of Cyprin-TD (Tinidazole) to induce the metabolism of other drugs has not been evaluated.
Elimination: The plasma half-life of Cyprin-TD (Tinidazole) is approximately 12-14 hours. Cyprin-TD (Tinidazole) is excreted by the liver and the kidneys. Cyprin-TD (Tinidazole) is excreted in the urine mainly as unchanged drug (approximately 20-25% of the administered dose). Approximately 12% of the drug is excreted in the feces.
Patients with impaired renal function: The pharmacokinetics of Cyprin-TD (Tinidazole) in patients with severe renal impairment (CrCL < 22 mL/min) are not significantly different from the pharmacokinetics seen in healthy subjects. However, during hemodialysis, clearance of Cyprin-TD (Tinidazole) is significantly increased; the half-life is reduced from 12.0 hours to 4.9 hours. Approximately 43% of the amount present in the body is eliminated during a 6-hour hemodialysis session . The pharmacokinetics of Cyprin-TD (Tinidazole) in patients undergoing routine continuous peritoneal dialysis have not been investigated.
Patients with impaired hepatic function: There are no data on Cyprin-TD (Tinidazole) pharmacokinetics in patients with impaired hepatic function. Reduction of metabolic elimination of metronidazole, a chemically-related nitroimidazole, in patients with hepatic dysfunction has been reported in several studies .
12.4 MicrobiologyMechanism of Action: Cyprin-TD (Tinidazole) is an antiprotozoal, antibacterial agent. The nitro- group of Cyprin-TD (Tinidazole) is reduced by cell extracts of Trichomonas. The free nitro- radical generated as a result of this reduction may be responsible for the antiprotozoal activity. Chemically reduced Cyprin-TD (Tinidazole) was shown to release nitrites and cause damage to purified bacterial DNA in vitro. Additionally, the drug caused DNA base changes in bacterial cells and DNA strand breakage in mammalian cells. The mechanism by which Cyprin-TD (Tinidazole) exhibits activity against Giardia and Entamoeba species is not known.
Antibacterial: Culture and sensitivity testing of bacteria are not routinely performed to establish the diagnosis of bacterial vaginosis ; standard methodology for the susceptibility testing of potential bacterial pathogens, Gardnerella vaginalis, Mobiluncus spp. or Mycoplasma hominis, has not been defined. The following in vitro data are available, but their clinical significance is unknown. Cyprin-TD (Tinidazole) is active in vitro against most strains of the following organisms that have been reported to be associated with bacterial vaginosis:
Antiprotozoal: Cyprin-TD (Tinidazole) demonstrates activity both in vitro and in clinical infections against the following protozoa: Trichomonas vaginalis; Giardia duodenalis (also termed G. lamblia); and Entamoeba histolytica.
For protozoal parasites, standardized susceptibility tests do not exist for use in clinical microbiology laboratories.
Drug Resistance: The development of resistance to Cyprin-TD (Tinidazole) by G. duodenalis, E. histolytica, or bacteria associated with bacterial vaginosis has not been examined.
Cross-resistance: Approximately 38% of T. vaginalis isolates exhibiting reduced susceptibility to metronidazole also show reduced susceptibility to Cyprin-TD (Tinidazole) in vitro. The clinical significance of such an effect is not known.
To reduce the development of drug-resistant bacteria and maintain the effectiveness of Cyprin-TD (Tinidazole) and other antibacterial drugs, Cyprin-TD (Tinidazole) should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria.
13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of FertilityMetronidazole, a chemically-related nitroimidazole, has been reported to be carcinogenic in mice and rats but not hamsters. In several studies metronidazole showed evidence of pulmonary, hepatic, and lymphatic tumorigenesis in mice and mammary and hepatic tumors in female rats. Cyprin-TD carcinogenicity studies in rats, mice or hamsters have not been reported.
Cyprin-TD (Tinidazole) was mutagenic in the TA 100, S. typhimurium tester strain both with and without the metabolic activation system and was negative for mutagenicity in the TA 98 strain. Mutagenicity results were mixed (positive and negative) in the TA 1535, 1537, and 1538 strains. Cyprin-TD (Tinidazole) was also mutagenic in a tester strain of Klebsiella pneumonia. Cyprin-TD (Tinidazole) was negative for mutagenicity in a mammalian cell culture system utilizing Chinese hamster lung V79 cells (HGPRT test system) and negative for genotoxicity in the Chinese hamster ovary (CHO) sister chromatid exchange assay. Cyprin-TD (Tinidazole) was positive for in vivo genotoxicity in the mouse micronucleus assay.
In a 60-day fertility study, Cyprin-TD (Tinidazole) reduced fertility and produced testicular histopathology in male rats at a 600 mg/kg/day dose level (approximately 3-fold the highest human therapeutic dose based upon body surface area conversions). Spermatogenic effects resulted from 300 and 600 mg/kg/day dose levels. The no observed adverse reaction level for testicular and spermatogenic effects was 100 mg/kg/day (approximately 0.5-fold the highest human therapeutic dose based upon body surface area conversions). This effect is characteristic of agents in the 5-nitroimidazole class.
13.2 Animal Toxicology and/or PharmacologyIn acute studies with mice and rats, the LD 50 for mice was generally > 3,600 mg/kg for oral administration and was > 2,300 mg/kg for intraperitoneal administration. In rats, the LD 50 was > 2,000 mg/kg for both oral and intraperitoneal administration.
A repeated-dose toxicology study has been performed in beagle dogs using oral dosing of Cyprin-TD (Tinidazole) at 100 mg/kg/day, 300 mg/kg/day, and 1000 mg/kg/day for 28-days. On Day 18 of the study, the highest dose was lowered to 600 mg/kg/day due to severe clinical symptoms. The two compound-related effects observed in the dogs treated with Cyprin-TD (Tinidazole) were increased atrophy of the thymus in both sexes at the middle and high doses, and atrophy of the prostate at all doses in the males. A no-adverse-effect level (NOAEL) of 100 mg/kg/day for females was determined. There was no NOAEL identified for males because of minimal atrophy of the prostate at 100 mg/kg/day (approximately 0.9-fold the highest human dose based upon plasma AUC comparisons).
14 CLINICAL STUDIES
14.1 TrichomoniasisCyprin-TD (2 g single oral dose) use in trichomoniasis has been well documented in 34 published reports from the world literature involving over 2,800 patients treated with Cyprin-TD (Tinidazole). In four published, blinded, randomized, comparative studies of the 2 g Cyprin-TD (Tinidazole) single oral dose where efficacy was assessed by culture at time points post-treatment ranging from one week to one month, reported cure rates ranged from 92% (37/40) to 100% (65/65) (n=172 total subjects). In four published, blinded, randomized, comparative studies where efficacy was assessed by wet mount between 7-14 days post-treatment, reported cure rates ranged from 80% (8/10) to 100% (16/16) (n=116 total subjects). In these studies, Cyprin-TD (Tinidazole) was superior to placebo and comparable to other anti-trichomonal drugs. The single oral 2 g Cyprin-TD (Tinidazole) dose was also assessed in four open-label trials in men (one comparative to metronidazole and 3 single-arm studies). Parasitological evaluation of the urine was performed both pre- and post-treatment and reported cure rates ranged from 83% (25/30) to 100% (80/80) (n=142 total subjects).
14.2 GiardiasisCyprin-TD (Tinidazole) (2 g single dose) use in giardiasis has been documented in 19 published reports from the world literature involving over 1,600 patients (adults and pediatric patients). In eight controlled studies involving a total of 619 subjects of whom 299 were given the 2 g × 1 day (50 mg/kg × 1 day in pediatric patients) oral dose of Cyprin-TD (Tinidazole), reported cure rates ranged from 80% (40/50) to 100% (15/15). In three of these trials where the comparator was 2 to 3 days of various doses of metronidazole, reported cure rates for metronidazole were 76% (19/25) to 93% (14/15). Data comparing a single 2 g dose of Cyprin-TD (Tinidazole) to usually recommended 5-7 days of metronidazole are limited.
14.3 Intestinal AmebiasisCyprin-TD use in intestinal amebiasis has been documented in 26 published reports from the world literature involving over 1,400 patients. Most reports utilized Cyprin-TD (Tinidazole) 2 g/day × 3 days. In four published, randomized, controlled studies (1 investigator single-blind, 3 open-label) of the 2 g/day × 3 days oral dose of Cyprin-TD (Tinidazole), reported cure rates after 3 days of therapy among a total of 220 subjects ranged from 86% (25/29) to 93% (25/27).
14.4 Amebic Liver AbscessCyprin-TD (Tinidazole) use in amebic liver abscess has been documented in 18 published reports from the world literature involving over 470 patients. Most reports utilized Cyprin-TD (Tinidazole) 2 g/day × 2-5 days. In seven published, randomized, controlled studies (1 double-blind, 1 single-blind, 5 open-label) of the 2 g/day × 2-5 days oral dose of Cyprin-TD (Tinidazole) accompanied by aspiration of the liver abscess when clinically necessary, reported cure rates among 133 subjects ranged from 81% (17/21) to 100% (16/16). Four of these studies utilized at least 3 days of Cyprin-TD (Tinidazole).
14.5 Bacterial VaginosisA randomized, double-blind, placebo-controlled clinical trial in 235 non-pregnant women was conducted to evaluate the efficacy of Cyprin-TD (Tinidazole) for the treatment of bacterial vaginosis. A clinical diagnosis of bacterial vaginosis was based on Amsel's criteria and defined by the presence of an abnormal homogeneous vaginal discharge that (a) has a pH of greater than 4.5, (b) emits a "fishy" amine odor when mixed with a 10% KOH solution, and (c) contains ≥20% clue cells on microscopic examination. Clinical cure required a return to normal vaginal discharge and resolution of all Amsel's criteria. A microbiologic diagnosis of bacterial vaginosis was based on Gram stain of the vaginal smear demonstrating (a) markedly reduced or absent Lactobacillus morphology, (b) predominance of Gardnerella morphotype, and (c) absent or few white blood cells, with quantification of these bacterial morphotypes to determine the Nugent score, where a score ≥4 was required for study inclusion and a score of 0-3 considered a microbiologic cure. Therapeutic cure was a composite endpoint, consisting of both a clinical cure and microbiologic cure. In patients with all four Amsel's criteria and with a baseline Nugent score ≥4, Cyprin-TD (Tinidazole) oral tablets given as either 2 g once daily for 2 days or 1 g once daily for 5 days demonstrated superior efficacy over placebo tablets as measured by therapeutic cure, clinical cure, and a microbiologic cure.

The therapeutic cure rates reported in this clinical study conducted with Cyprin-TD (Tinidazole) were based on resolution of 4 out of 4 Amsel's criteria and a Nugent score of <4. The cure rates for previous clinical studies with other products approved for bacterial vaginosis were based on resolution of either 2 or 3 out of 4 Amsel's criteria. At the time of approval for other products for bacterial vaginosis, there was no requirement for a Nugent score on Gram stain, resulting in higher reported rates of cure for bacterial vaginosis for those products than for those reported here for Cyprin-TD (Tinidazole).
17 PATIENT COUNSELING INFORMATION
17.1 Administration of DrugPatients should be told to take Cyprin-TD with food to minimize the incidence of epigastric discomfort and other gastrointestinal side-effects. Food does not affect the oral bioavailability of Cyprin-TD (Tinidazole).
17.2 Alcohol AvoidancePatients should be told to avoid alcoholic beverages and preparations containing ethanol or propylene glycol during Cyprin-TD (Tinidazole) therapy and for 3 days afterward because abdominal cramps, nausea, vomiting, headaches, and flushing may occur.
17.3 Drug ResistancePatients should be counseled that antibacterial drugs including Cyprin-TD (Tinidazole) should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When Cyprin-TD (Tinidazole) is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by Cyprin-TD (Tinidazole) or other antibacterial drugs in the future.
