Bioequivalence Study of 120 mg Etoricoxib Film-coated Tablets

Study Overview
=================
Brief Summary
-----------------
The present study was a randomized, open-label, two-period, two-sequence, cross-over study, conducted to find out whether the etoricoxib 120 mg film-coated tablet produced by PT Dexa Medica (test drug) was bioequivalent to the reference drug (Arcoxia® Film-Coated Tablet 120 mg, PT. Schering-Plough Indonesia Tbk), under fasting condition with a fourteen days wash-out period, involving 26 healthy adult male and female subjects.

Detailed Description
-----------------
This was a randomized, open-label, two-period, two-sequence, cross-over study under fasting condition with a fourteen days wash-out period, involving 26 healthy adult male and female subjects. The participating subjects had an overnight fast and in the next morning were given orally either one film-coated tablet of the test drug or one film-coated tablet of the reference drug with 200 mL of water. Blood samples were drawn immediately before taking the drug (baseline), and at 15, 30, and 45 minutes and 1, 1.5, 2, 3, 4, 6, 8, 12, 18, 24, 36, 48, and 72 hours after drug administration, analysed for plasma concentrations of etoricoxib and used to evaluate the pharmacokinetics parameters of the single dose administration. After a fourteen-day washout period, the procedure was repeated using the alternate drug. The plasma concentrations of etoricoxib were determined by using a high pressure liquid chromatography with ultraviolet detection (HPLC-UV) method.
