Physico-chemical and solid-state characterization of secnidazole.

Secnidazole (hydroxy-2-propyl)-l-methyl-2-nitro-5-imidazole) is an antimicrobic agent. This drug has pharmacological activity against intestinal and hepatic amebiasis, giardiasis and vaginal trichomoniasis. This paper shows the physicochemical parameters of secnidazole determined during a preformulation study.
