Detailed Description:

This randomized, single-dose, two-way, crossover study was conducted to compare the relative bioavailability of two formulations of 1000 mg metformin hydrochloride tablets under fed conditions. The study was conducted with 32 (30 completing) healthy adults in accordance with Protocol No. 10640303 (Revision 0). In each study period, a single dose (1 x 1000 mg tablet) was administered to all subjects following a standardized high fat breakfast preceded by an overnight fast of at least 10 hours. The test formulation was Ohm Laboratories, Inc's (A Group of Ranbaxy Pharmaceuticals Inc.) Metformin Hydrochloride 1000 mg Tablets and the reference formulation was GLUCOPHAGE® (metformin hydrochloride) 1000 mg Tablets (Bristol-Myers Squibb Company). The subjects received the test product in one study period and the reference product in the other period; the order of administration was according to the dosing randomization schedule. There was a 7-day interval between treatments.

Blood samples were collected pre-dose and at intervals over 24 hours after each dose. The plasma samples for all subjects completing both periods of the study were sent to Helen Fassoulas, Director of Operations, Warnex Bioanalytical Services Inc., 3885 boul Industriel, Laval, Quebec, H7L4S3 Canada, Telephone: 450-663-6724, Fax: 450-975-8111 for determination of metformin concentrations.

Statistical analysis was performed by Braulio Suarez, M.D., Novum Pharmaceutical Research Services, Wilcrest Green Office Park, 3320 Walnut Bend Lane, Houston, Texas 77042-4712, USA, Telephone: 832-251-8100, Fax: 832-251-7133.

A total of 32 healthy adult subjects (30 completing).
