Bioequivalence and pharmacokinetic comparison of 3 metformin extended/sustained release tablets in healthy Indian male volunteers.

This study was undertaken to compare the bioavailability and pharmacokinetic properties of 3 marketed product of metformin (CAS 1115-70-4) extended/sustained release formulation in Indian male volunteers. Study was designed as an open-label, randomized, 3-treatment, single-dose, crossover, bioavailability study comparing 3 marketed brands of 500 mg metformin extended/sustained release tablets in 18 healthy human male volunteers under fed condition. A single oral dose of 500 mg metformin sustained release products, test A (Glycomet SR), test B (Bigomet SR) and extended release reference product was administered as per computer generated randomization schedule during 3 period of the study having 7 days of washout period.

Pharmacokinetics and bioequivalence study of three oral formulations of valsartan 160 mg: a single-dose, randomized, open-label, three-period crossover comparison in healthy Indian male volunteers.

Background: Valsartan is a selective angiotensin II type 1 receptor blocker indicated for the treatment of hypertension. Although the bioavailability and pharmacokinetic properties of valsartan have been well characterized, a literature search did not identify any reports concerning the bioavailability of valsartan in the Indian population.

Objective: This study was undertaken to compare the pharmacokinetic properties of 2 branded generic valsartan formulations (tests A and B) with a branded innovator product (reference) in healthy Indian male subjects.
