Bioavailability of metronidazole formulations (Vagimid).
The bioavailability of metronidazole (0.5 g) from Vagimid tablets and dragées were compared with tablets of a reference formulation in 12 male healthy volunteers (age 20-32 years, body weight 61-77 kg). Metronidazole and its two main oxidized metabolites in serum were determined quantitatively with an hplc method. Metronidazole from Vagimid tablets was absorbed more rapidly than from the reference but at the same extent of absorption. The pharmacokinetic profile of Vagimid dragées was similar to the behaviour of the reference but AUC of dragées was slightly but significantly lower. All elimination parameters of metronidazole as well as the formation of the two metabolites were not different after administration of the oral formulations.
