Comparative Bioavailability Study of Clarithromycin 500 mg Tablets in Fasting State

The objective of this study was to investigate the bioequivalence of Genpharm's clarithromycin tablets following a single, oral 500 mg (1 x 500 mg) dose compared to the Biaxin® filmtab® (Abbott Laboratories USA) administered under fasting conditions. Sixty-four (64) healthy, light-, non- or ex-smoking subjects of at least 18 a years of age were randomized, in this two-period, two-treatment crossover bioequivalence study conducted by Eric Sicard, M.D. at Algorithme Pharma Inc. Montreal, Canada.

Statistical analysis of the data reveals that 90% confidence intervals are within the acceptable bioequivalent range of 80% and 125% for the natural log transformed parameters AUCT, AUCI and Cmax. This study demonstrates that Genpharm's clarithromycin 500 mg tablets are bioequivalent to Biaxin® filmtab® 500 mg tablets (Abbott Laboratories USA) administered under fasting conditions.
