Tiprogyn

Tiprogyn Uses, Dosage, Side Effects, Food Interaction and all others data.

Tiprogyn, a 5-nitroimidazole derivative with antimicrobial actions similar to metronidazole, is active against both protozoa (e.g. Trichomonas vaginalis, Entamoeba histolytica and Giardia lamblia) and obligate anaerobic bacteria. It damages DNA strands or inhibits DNA synthesis in microorganism.

Tiprogyn is a synthetic antiprotozoal agent. Tiprogyn demonstrates activity both in vitro and in clinical infections against the following protozoa: Trichomonas vaginalis, Giardia duodenalis (also termed G. lamblia), and Entamoeba histolytica. Tiprogyn does not appear to have activity against most strains of vaginal lactobacilli.

Uses

Trichomoniasis: Tiprogyn is used 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.

Giardiasis: Tiprogyn is used for the treatment of giardiasis caused by Giardia duodenalis in both adults and pediatric patients older than three years of age. Sections or subsections omitted from the full prescribing information are not listed.

Amebiasis: Tiprogyn is used 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 used for the treatment of asymptomatic cystpassage.

Bacterial Vaginosis: Tiprogyn is used 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 Tiprogyn and other antibacterialdrugs, Tiprogyn 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.

Tiprogyn is also used to associated treatment for these conditions: Amebiasis, Bacterial Vaginosis (BV), Candidal Vulvovaginitis, Giardiasis, Mixed Vaginal Infections, Nongonococcal urethritis, Sexually Transmitted Disease (STD), Trichomonas Vaginalis Infection, Trichomoniasis

How Tiprogyn works

Tiprogyn is a prodrug and antiprotozoal agent. The nitro group of tinidazole is reduced in Trichomonas by a ferredoxin-mediated electron transport system. The free nitro radical generated as a result of this reduction is believed to be responsible for the antiprotozoal activity. It is suggested that the toxic free radicals covalently bind to DNA, causing DNA damage and leading to cell death. The mechanism by which tinidazole exhibits activity against Giardia and Entamoeba species is not known, though it is probably similar.

Prevention of Postoperative Infections :

  • Adult: A single oral dose of 2g approximately 12 hours before surgery.
  • Children less than 12 years: Data are not available to allow dosage recommendations for children below the age of 12 years in the prophylaxis of anaerobic infections.

Trichomoniasis: a single 2 g oral dose taken with food. Treat sexual partners with the same dose and at the same time Giardiasis:

  • Adults: a single 2 g dose taken with food.
  • Pediatric patients older than three years of age: a single dose of 50 mg/kg (up to 2 g) with food

Amebiasis, Intestinal:

  • Adults: 2 g per day for 3 days with food.
  • Pediatric patients older than three years of age: 50 mg/kg/day (up to 2 g per day) for 3 days with food

Amebic liver abscess:

  • Adults: 2 g per day for 3-5 days with food.
  • Pediatric patients older than three years of age: 50 mg/kg/day (up to 2 g per day) for 3-5 days with food

Bacterial vaginosis: Non-pregnant, adult women: 2 g once daily for 2 days taken with food, or 1 g once daily for 5 days taken with food.

Should be taken with food. Take during or immediately after meals.

Side Effects

Reported side effects have generally been infrequent, mild and self-limiting. Side effects from the gastrointestinal tract include nausea, vomiting, anorexia, diarrhoea and metallic taste. Hypersensitivity reactions, occasionally severe, may occur in rare cases in the form of skin rash, pruritis, urticaria and angioneurotic oedema. As with related compounds, tinidazole may produce transient leukopenia. Other rarely reported side-effects are headache, tiredness, furry tongue and dark urine.

Toxicity

There are no reported overdoses with tinidazole in humans. In 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.

Precaution

Compounds of similar chemical structure have produced various neurological disturbances such as dizziness, vertigo, uncoordination, and ataxia. If, during therapy with tinidazole, abnormal neurological signs develop, therapy should be discontinued. Use in Pregnancy & Lactation: Tiprogyn is contraindicated during the first trimester of pregnancy. While there is no evidence that tinidazole is harmful during the late stages of pregnancy, its use during the last two trimesters requires that the potential benefits outweigh the possible risk to mother and foetus. Tiprogyn is excreted in breast milk in concentrations similar to those seen in serum. Tiprogyn can be detected in breast milk for up to 72 hours following administration. Interruption of breast-feeding is recommended during tinidazole therapy and for 3 days following the last dose.

Interaction

The following interactions were reported with metronidazole, which is chemically-related to tinidazole.

Alcohol, disulfiram: Avoid during tinidazole use and for 3 days afterward because cramps, nausea, vomiting, headaches, and flushing may occur.

Anticoagulants, oral (eg, warfarin): Anticoagulant effects may be increased. Anticoagulant dose may need to be adjusted during coadministration and for up to 8 days after discontinuation.

Cholestyramine: Bioavailability of tinidazole may be decreased. Cyclosporine, lithium, tacrolimus: Levels may be elevated by tinidazole, increasing the risk of toxicity.

Drugs that induce CYP3A4 (eg, fosphenytoin, phenobarbital, phenytoin, rifampin): May increase metabolism of tinidazole, decreasing plasma levels and therapeutic effect.

Drugs that inhibit CYP3A4 (eg, cimetidine, ketoconazole): May prolong t½ and decrease tinidazole Cl, increasing plasma levels and risk of adverse reactions.

Fluorouracil: Cl may be decreased by tinidazole, increasing the risk of adverse reactions

Fosphenytoin, phenytoin: The t½ may be prolonged and Cl reduced by tinidazole, increasing the risk of adverse reactions.

Oxytetracycline: Therapeutic effect of tinidazole may be decreased.

Food Interaction

  • Avoid alcohol. Avoid concomitant use of alcohol with tinidazole as it may cause flushing, nausea, vomiting, and headaches.
  • Take with food. Administering with food may reduce gastrointestinal upset and epigastric discomfort caused by tinidazole but does not affect bioavailability.

[Moderate] GENERALLY AVOID: Use of alcohol or products containing alcohol during nitroimidazole therapy may result in a disulfiram-like reaction in some patients.

There have been a few case reports involving metronidazole, although data overall are not convincing.

The presumed mechanism is inhibition of aldehyde dehydrogenase (ALDH) by metronidazole in a manner similar to disulfiram.

Following ingestion of alcohol, inhibition of ALDH results in increased concentrations of acetaldehyde, the accumulation of which can produce an unpleasant physiologic response referred to as the 'disulfiram reaction'.

Symptoms include flushing, throbbing in head and neck, throbbing headache, respiratory difficulty, nausea, vomiting, sweating, thirst, chest pain, palpitation, dyspnea, hyperventilation, tachycardia, hypotension, syncope, weakness, vertigo, blurred vision, and confusion.

Severe reactions may result in respiratory depression, cardiovascular collapse, arrhythmia, myocardial infarction, acute congestive heart failure, unconsciousness, convulsions, and death.

However, some investigators have questioned the disulfiram-like properties of metronidazole.

One study found neither elevations in blood acetaldehyde nor objective or subjective signs of a disulfiram-like reaction to ethanol in six subjects treated with metronidazole (200 mg three times a day for 5 days) compared to six subjects who received placebo.

MANAGEMENT: Because clear evidence is lacking concerning the safety of ethanol use during nitroimidazole therapy, patients should be apprised of the potential for interaction and instructed to avoid alcoholic beverages and products containing alcohol or propylene glycol while using oral, intravenous, or vaginal preparations of a nitroimidazole.

Alcoholic beverages should not be consumed for up to 3 days after completion of systemic nitroimidazole therapy.

Pregnancy & Breastfeeding use

Pregnancy Category C. Either studies in animals have revealed adverse effects on the foetus (teratogenic or embryocidal or other) and there are no controlled studies in women or studies in women and animals are not available. Drugs should be given only if the potential benefit justifies the potential risk to the foetus.

Contraindication

As with other compounds of similar structure, tinidazole, is contraindicated in patients having, or with a history of, blood dyscrasias although no persistent haematological abnormalities have been noted in clinical or animal studies. Tiprogyn should be avoided in patients with organic neurological disorders. Tiprogyn should not be administered to patients with known hypersensitivity to the compound.
