Tindamax (Tinidazole) - Summary

 
 



WARNING: POTENTIAL RISK FOR CARCINOGENICITY

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 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).

 

TINDAMAX SUMMARY

Tinidazole is a synthetic antiprotozoal and antibacterial agent.

Trichomoniasis

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 [see Clinical Studies ].

Giardiasis

Tinidazole 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 [see Clinical Studies].

Amebiasis

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 [see Clinical Studies (14.3, 14.4)].

Bacterial Vaginosis

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 [see Use in Specific Populations and Clinical Studies].

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 Tindamax and other antibacterial drugs, Tindamax 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.

NEWS HIGHLIGHTS

Published Studies Related to Tindamax (Tinidazole)

Tinidazole vs metronidazole for the treatment of bacterial vaginosis. [2011.03]
OBJECTIVE: The purpose of this study was to compare the efficacy of 2 different doses of tinidazole with metronidazole for the treatment of bacterial vaginosis and to compare the side effects of the drugs... CONCLUSION: There were no differences in cure rates between metronidazole and either of the tinidazole dosing regimens that were studied. In addition, there were no important differences in the side-effect profiles of metronidazole and tinidazole. Copyright (c) 2011 Mosby, Inc. All rights reserved.

Improved cure of bacterial vaginosis with single dose of tinidazole (2 g), Lactobacillus rhamnosus GR-1, and Lactobacillus reuteri RC-14: a randomized, double-blind, placebo-controlled trial. [2009.02]
Bacterial vaginosis (BV) is the most prevalent vaginal infection worldwide and is characterized by depletion of the indigenous lactobacilli... This study shows that probiotic lactobacilli can provide benefits to women being treated with antibiotics for an infectious condition.

Effectiveness of Two Tinidazole Regimens in Treatment of Bacterial Vaginosis: A Randomized Controlled Trial. [2007.08]
OBJECTIVE: To assess the effectiveness at 21-30 days after treatment of tinidazole administered orally at 1 g once daily for 5 days and 2 g once daily for 2 days, compared with placebo, in the treatment of bacterial vaginosis, using rigorous U.S. Food and Drug Administration (FDA)-recommended criteria to define cure... CONCLUSION: Both tinidazole regimens studied provided effective treatment for bacterial vaginosis. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, www.clinicaltrials.gov, NCT00229216 LEVEL OF EVIDENCE: I.

A randomized, controlled, open-label trial of a single day of mebendazole versus a single dose of tinidazole in the treatment of giardiasis in children. [2006.11]
CONCLUSIONS: Three doses of mebendazole, in a single day, are inferior to a single dose tinidazole in the treatment of giardiasis.

One-week versus two-week H2-receptor antagonist in combination with amoxicillin and tinidazole for eradication of Helicobacter pylori infection. [2005.09]
CONCLUSIONS: A 2-week course of high-dose H2-RA-based triple therapy is well tolerated and sufficiently effective in eradicating H. pylori infection. Presence of metronidazole resistance has a negative impact on the treatment efficacy.

Clinical Trials Related to Tindamax (Tinidazole)

NGU: Doxycycline (Plus or Minus Tinidazole) Versus Azithromycin (Plus or Minus Tinidazole) [Completed]
This study will look at the safety, effectiveness, and tolerability of combination medications for the initial treatment of non-gonococcal urethritis (NGU). NGU is inflammation of the tube that carries urine from the bladder. NGU is caused by bacteria that may be passed from person to person during sex. This study will compare the 2 currently recommended NGU treatments, doxycycline and azithromycin, taken with tinidazole (another medication to treat certain sexually transmitted infections). Tinidazole used with doxycycline or azithromycin may cure NGU better than when doxycycline or azithromycin is used alone. Study participants will be 300 men ages 16-45 years with NGU attending sexually transmitted disease clinics in Birmingham, AL; New Orleans, LA; Durham, NC; and Baltimore, MD. Study participation will last 7 weeks and involve 3 visits. At each visit, participants will provide a urine sample, have 2 urethral swabs, and have their urethra checked for discharge indicating infection.

Treatment of Bacterial Vaginosis (BV) With Tinidazole [Completed]
We are trying to determine if treatment of bacterial vaginosis with tinidazole is better than treatment with metronidazole

Tinidazole Versus Cefazolin Antibiotic Prophylaxis of Vaginal and Abdominal Hysterectomy [Active, not recruiting]
Purpose: to compare the efficacy of tinidazole and cefazolin on the prophylaxis of the febrile and infectious morbidity after vaginal or abdominal hysterectomy. Methods: A randomized clinical trial carried out at the Women's Integrated Healthcare Center (CAISM)/UNICAMP, Campinas, Brazil. Women undergoing to total vaginal or abdominal hysterectomy were randomly enrolled into one of these three groups of antibiotic prophylaxis: tinidazole, cefazolin or an association of both.

Crossover Bioequivalence Study of Tinidazole 500 mg Tablets Under Fed Conditions [Completed]
The objective of this study was to prove the bioequivalence of Roxane Laboratories' Tinidazole 500 mg Tablet under fed conditions.

Tinidazole for Recurrent Bacterial Vaginosis: A Pilot Study [Completed]
This research study is being done to evaluate the use of an oral (by mouth) medication called tinidazole to initially treat BV and then to see if additional treatment with tinidazole keeps women from getting this infection back within 3 months. Tinidazole is currently approved by the United States Food and Drug Administration (FDA) to treat bacterial vaginosis (BV). This study will evaluate the use of tinidazole to treat a woman's current BV infection and then will look at using tinidazole as a suppressive treatment (taking medication regularly to attempt to decrease the "bad" bacteria from growing back). The suppressive treatment phase will include using tinidazole twice a week compared to using placebo twice a week and then following women for recurrence of BV. The purpose of this study is to determine if tinidazole suppression will prevent BV from coming back within 3 months of treatment. The investigators hypothesize that women with a history of recurrent bacterial vaginosis who are randomized to a suppressive regimen (a dose of medication given on a regular basis to attempt to control the bacteria that causes bacterial vaginosis) of tinidazole will have lower recurrence rates and a longer time to recurrence of bacterial vaginosis when compared to those women randomized to placebo.
