A validated, accurate and sensitive LC-MS/MS method for determination of racemic methylphenidate and its metabolite ritalinic acid has been developed. The analytes were quantified by tandem mass spectrometry operating in positive electrospray ionization mode with multiple reaction monitoring. Blood, plasma

Methylphenidate is the most commonly prescribed psychostimulant in clinical use today. Known methylphenidate metabolites include ritalinic acid, corresponding lactams, and p-hydroxymethylphenidate. Recent in vitro work using rat liver preparations has indicated that the methylphenidate ethyl ester, ethylphenidate, is formed upon

A gas chromatographic-mass spectrometric method was developed for the stereoselective quantification of threo-methylphenidate (MPD) and its metabolite, ritalinic acid (RA), in plasma or urine. The plasma concentrations of (+)-MPD after oral administration of two 10-mg conventional tablets containing racemic MPD.HCl
