Summary
The object of this study was to compare the relative bioavailability (rate and extent of absorption) of 100/25 mg Losartan potassium/Hydrochlorothiazide Tablets manufactured by Teva Pharmaceutical Industries Ltd. and distributed by Teva Pharmaceuticals USA with that of Hyzaar® 100/25 mg Tablets distributed by Merck & Co., Inc. following a single oral dose (1 x 100/25 mg tablet) in healthy adult subjects administered under fasting conditions.
