An LC/MS/MS method for the simultaneous determination of cilostazol, a quinolinone derivative, and three active metabolites, OPC-13015, OPC-13213, and OPC-13217, in human plasma was developed and validated. Cilostazol, its metabolites, and the internal standard, OPC-3930 were extracted from human plasma

A study was undertaken for the characterization and quantitative determination of the main urinary metabolites of the non-steroidal anti-inflammatory drug (NSAID) nimesulide (4-nitro-2-phenoxy-methanesulfonanilide) in man following single oral administration (200 mg). Urines were collected from six healthy volunteers at 12
