Quality equivalence and in-vitro antibiotic activity test of different brands of amoxicillin/clavulanic acid tablets in Mwanza, Tanzania: A cross sectional study.

Background: Each film coated tablet of amoxicillin/clavulanic acid contains 500 mg of amoxicillin as an active pharmaceutical ingredient and 125 mg of clavulanic acid. Different brands have the same active ingredients but different excipients, which may cause differences in efficacy. With the emergence of generic antibiotics post-patent expiration, the antibiotic activity of generics is in question in comparison to the innovator.
