Brief Summary
The main purpose of this study is to compare the pharmacokinetic profile to establish the better controlled liberation of the test product (Tramadol HCL OAD tablets of 200 mg, Labopharm) and its bioavailability in relation with the commercialised reference (Zytram® tablets of 200 mg, Zambon), single dose administered.

Outcome Measures
Primary Outcomes (3)
AUC(0-t)
Area under the plasma concentration versus time curve to the last measured concentration. h=hour
48 hours
AUC (0-∞)
The area under the plasma concentration curve was estimated by extrapolating to infinity AUC0-t. The extrapolation to infinity was done by regression with the last log-transformed data to estimate the terminal area by means of the line that maximized R'2 (coefficient of determination). The units are ng.h/mL. h=hours
