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
Martin Josefsson et al.
Journal of pharmaceutical and biomedical analysis, 55(5), 1050-1059 (2011-04-19)
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

Six adults phenotyped as either extensive (N = 4) or poor (N = 2) metabolizers for cytochrome P450 (CYP) 2D6 were given a 10-mg oral dose of methylphenidate (MPH) on two separate occasions with and without quinidine, a potent CYP2D6
Ragnar Thomsen et al.
Journal of analytical toxicology, 36(8), 560-568 (2012-07-27)
A chiral liquid chromatography tandem mass spectrometry (LC-MS-MS) method was developed and validated for quantifying methylphenidate and its major metabolite ritalinic acid in blood from forensic cases. Blood samples were prepared in a fully automated system by protein precipitation followed
