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

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
N R Srinivas et al.
Journal of chromatography, 530(2), 327-336 (1990-09-14)
Enantioselective gas chromatographic assays for the quantitation of methylphenidate and its major metabolite ritalinic acid in plasma are described. The procedures involved the extraction of methylphenidate enantiomers from alkanised plasma. The plasma was then washed to ensure complete removal of

The pharmacokinetics of methylphenidate (MPH), a prescription amphetamine derivative used in the treatment of attention-deficit hyperactivity disorder, has been amply described in conventional biological matrices. Recently, the excretion of MPH and its principal metabolite, ritalinic acid (RA) in oral fluid
