Bioequivalence Study of Mycophenolate Mofetil 500 mg Tablets of Dr.Reddy's Laboratories Limited Under Fasting Conditions

Study Overview
=================
Brief Summary
-----------------
To compare the bioavailability and characterise the pharmacokinetic profile of the sponsor's test formulation with respect to the reference formulation Cellcept® 500 mg tablets, in healthy, adult, human male subjects under fasting conditions and to assess the bioequivalence.

Detailed Description
-----------------
This was an open-label, balanced, randomized, two-treatment, four-period, two-sequence,single dose, replicate crossover bioequivalence study in healthy, adult, human, male subjects under fasting conditions.48 healthy male adults were enrolled.A washout period of 07 days was maintained between the successive dosing days.One tablet containing mycophenolate mofetil 500 mg was administered orally with 240 mL water in sitting posture, after an overnight fast of at least 10 hours in each period. This activity was followed by a mouth check to assess compliance to dosing. The subjects were not allowed to lie down for the first three hours after dosing.
