Abstract:
Objective To improve a HPLOUV method for the determination of Tramadol hydrochlo-ride in human plasma. Method Alkalinized samples of plasma were extracted with dichloromethane. Tramadol and internai standard were analyzed on Elite C18 column (200mm?5.0mm, 5?m) with a acetoni-trile-phsphate buffer (pH6.5) (74:26, v/v) mobile phase and detedted at 220nm. Results The Calibra-tion plots in human plasma were linear (r=0.9984, n =5) from 10 to 800 ng/ml. The limit of detection was 10 ng/ml. For 20, 100, 400 ng/ml check samples, intra-run precisions (RSD) were 3.81% -5.44% and inter-run preceisions (RSD) were 3.95% -4.41% , respectively. The average recoveries were 89% , 96% and 92% for the low, middle and high check samples, respectively. Conclusion The improved ana-lytical method for Tramadol hydrochloride was found to be sensitive, simple and rapid, suitable for applica-tion in forensic toxicological analysis and routine determination of numerous samples.
