Pharmacokinetic Properties of Nevirapine Extended Release Tablets When Administered Orally in Healthy Male Volunteers

An Open-label, Randomised, Single Dose, Parallel-group Phase I Study to Investigate the Pharmacokinetic Properties of 200 mg Nevirapine Extended Release Tablets When Administered Orally as 2x100 mg Tablets or as 4x50 mg Tablets in Healthy Male Volunteers

Study to determine the pharmacokinetic properties of 200 mg nevirapine (NVP) administered as 4 x 50 mg extended release (XR) tablets in a single dose and to establish the bioequivalence of this formulation compared to 200 mg NVP administered as 2 x 100 mg XR tablets in a single dose
