Dược Động Học :
▧ 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.
▧ Volume of Distribution :
* 50 L
▧ Protein binding :
Plasma protein binding of tinidazole is 12%.
▧ Metabolism :
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.
