Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed 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.
