Bioequivalence Study of 3 mg Glimepiride Tablet in Indonesia Healthy Subjects

The study was conducted toinvestigate whether the bioavailability of 3 mg Glimepiride Tablet Manufactured by PT. Harsen Laboratories was bioequivalent to the reference product, 3 mg Amaryl® Tablet Manufactured by PT. Aventis Indonesia Pharma, Indonesia.

The study was conducted following an oral administration of one tablet of the test drug (3 mg Glimepiride Tablet) or one tablet of the reference drug (3 mg Amaryl® Tablet ). Blood samples were drawn before dosing (0 h) and at 15, 30, 45 minutes, and 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 9, 12, 18, 24, and 30 hours after drug administration. The entire subjects were given 60 mL of 20% glucose solution to minimize hypoglycemic effects at 15, 30, 45 minutes, and 1, 1.25, 1.5, 1.75, 2, 2.25, 2.5, 2.75, 3, 3.25, 3.5, 3.75 and 4 hours after drug administration. Following a washout period of one week, this procedure was repeated using the alternate drug. The plasma concentrations of glimepiride were determined by means of LC-MS/MS system. The LLOQ is 1.99 ng/mL of glimepiride. The pharmacokinetic parameters used in this study were area under the concentration-time curve of glimepiride from time zero to 30 hours (AUCt), area under the concentration-time curve from time zero to infinite (AUCinf), maximum concentration (Cmax), time required to reach the maximum concentration (tmax) and the elimination half life (t½).
