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

To investigate the occurrence and fate of ritalinic acid - the main human metabolite of the psychostimulant drug methylphenidate - in the aquatic environment, a HPLC-electrospray-MS/MS method for the quantification of ritalinic acid in wastewater, surface water and bank filtrate
A Solans et al.
Journal of chromatography. B, Biomedical applications, 658(2), 380-384 (1994-08-19)
Two analytical methods for the simultaneous detection in urine of methylphenidate and its main metabolite, ritalinic acid, are described. Both procedures are based on solid-phase extraction of urine samples on Bond Elut Certify columns, and capillary gas chromatographic-mass spectrometric detection

Journal of clinical psychopharmacology, 19(4), 362-366 (1999-08-10)
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
