Action
Description: Secnidazole, a 5-nitroimidazole derivative, is an antiprotozoal and antibacterial agent. Its mechanism of action is not fully elucidated, but it is believed to be activated following its entry as inactive prodrug into the microorganisms, where it is reduced by low oxidation-reduction potential ferredoxin, thus resulting in DNA damage.
Pharmacokinetics:
Absorption: Time to peak plasma concentration: 4 hours (range: 3-4 hours).
Distribution: Volume of distribution: Approx 42 L. Plasma protein binding: <5%.
Metabolism: Metabolised in the liver via oxidation by the CYP450 enzyme system into metabolites.
Excretion: Via urine (approx 15% as unchanged drug). Elimination half-life: Approx 17 hours.
