About

The purpose of this study is to determine the bioequivalence of Metronidazole benzoate (400 mg metronidazole per sachet oral granules)/Terix Labs Ltd and Flagyl™ 400 mg Tablets (400 mg metronidazole per film coated tablet)/Zentiva.

Full description

This study aims to compare the absorption and disposition kinetics of two products containing metronidazole under fasting conditions. These products are: Metronidazole benzoate (400 mg metronidazole per sachet oral granules)/Terix Labs Ltd, Test product manufactured by ONE PHARMA, Greece and Flagyl™ 400 mg Tablets (400 mg metronidazole per film coated tablet)/Zentiva, a Reference product manufactured by Famar Health Care Services, Spain. The bioequivalence of a single 400 mg dose of both products will be assessed by comparing the pharmacokinetic parameters derived from the plasma concentration-time profiles for metronidazole.
