bioequivalence study of amoxicillin dispersible 600 mg tablets under fasting conditions

Conditions: Healthy

Summary: this study compared the relative bioavailability (rate and extent of absorption) of amoxicillin tablets for oral suspension 600 mg by ranbaxy laboratories limited with that of amoxil ® for oral suspension 400 mg/ 5 ml by smithkline beecham pharmaceuticals following single oral dose (600 mg) in healthy, adult, subjects under fasting conditions using a randomized two-way crossover design.

a single oral dose of the test or reference product was administered to volunteers on two separate occasions under fasting conditions with at least a 7 day washout between the doses. twenty-six healthy volunteers were randomly assigned to the test or the reference products. food and fluid intake were controlled during each confinement period. twenty six (26) healthy subjects (16 males and 10 females) were enrolled in the study, of which 25 subjects completed the clinical phase of the study.
