Bioequivalence Study of Gliclazide 120 mg Modified Release Tablets

Comparative Randomized, Single Dose, Three-period Crossover Open-label Study to Determine the Bioequivalence of Gliclazide 120 mg Modified Release Tablets Formula A and Gliclazide 120 mg Modified Release Tablets Formula B Manufactured by Indeus Life Sciences PVT. Ltd., Relative to DIAMICRON MR® 60 mg 2 × of Les Laboratories Servier Industrie, France, After an Oral Administration of 120 mg to Healthy Adults Under Fasting Conditions

The main purpose of this study is to assess comparative bioavailability of two test formulations of Gliclazide 120 mg Modified Release tablets (120 mg gliclazide per modified release tablet) Manufactured By Indeus Life Sciences Pvt. Ltd., Mumbai India (An Affiliate Of Disphar International B.V., The Netherlands) Relative To DIAMICRON MR® 60 mg 2 × (60 mg gliclazide per modified release tablet) Of Les Laboratories Servier Industrie, France in 15 healthy adult subjects under fasting conditions. The second aim is to asses the safety of subjects and to determine other pharmacokinetic data.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Time Frame
AUC(0-t) defined as The area under the plasma concentration versus time curve, from time (0) to the last measurable concentration (t), as calculated by the linear trapezoidal method.	Blood drawn before dosing and at following times after the dose: 0.5, 1, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 10, 11, 12, 16, 24, 48 and 72 hours
