| Pharmacology: |
Tinidazole is a synthetic antiprotozoal agent. 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. Tinidazole does not appear to have activity against most strains of vagina...

| Mechanism of Action: |
Tinidazole 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 ...

| Absorption: | Rapidly and completely absorbed under fasting conditions. Administration with food results in a delay in Tmax of approximately 2 hours and a decline in Cmax of approximately 10% and an AUC of 901.6 ± 126.5 mcg hr/mL. |
| Protein binding: | Plasma protein binding of tinidazole is 12%. |
| Biotransformation: | Hepatic, mainly via CYP3A4. Tinidazole, like metronidazole, is significantly metabolized in humans prior to excretion. Tinidazole is partly metabolized by oxidation, hydroxylation and conjugation. Tinidazole is the major drug-related constituent in plasma after human treatment, along with a small amount of the 2-hydroxymethyl metabolite. |
| Route of elimination: | Tinidazole crosses the placental barrier and is secreted in breast milk. Tinidazole is excreted by the liver and the kidneys. 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. |
| Half Life: | Elimination half-life is 13.2 ± 1.4 hours. Plasma half-life is 12 to 14 hours. |
| 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. |
| Affected organisms: | Trichomonas vaginalis, Giardia duodenalis, and Entamoeba histolytica |
