About this study
Official title: Comparative, Randomized, Single Dose, 2-Way Crossover Relative Bioavailability Study of Ranbaxy and Ortho-Mcneil Pharmaceutical (Topamax®) 25 mg Topiramate Tablets Following a 50 mg Dose in Healthy Adult Males Under Fed Conditions
The objective of this study was to compare the single-dose relative bioavailability of Ranbaxy and Ortho-McNeil Pharmaceutical (Topamax®) 25 mg topiramate tablets following a 50 mg dose under fed conditions.
Read the detailed description
This was an open-label, randomized, single-dose, 2-way crossover, relative bioavailability study performed on 18 healthy adult male volunteers. A total of 17 subjects completed the clinical phase of the study. In each period, subjects were housed from the evening before dosing until after the 24-hour blood draw. Subjects were to return for the 48-, 72-, 96- and 120-hour blood draws. Both periods were separated by a washout period of 14 days.
