title: Determination of three main antileprosy drugs and their main metabolites in serum by high-performance liquid chromatography.
abstract: The simultaneous analysis of main antileprosy drugs such as 4,4'-diaminodiphenyl sulfone (DDS), clofazimine, rifampicin and their main metabolites in serum was examined by high-performance liquid chromatography using a muBondapak C18 column. When the drugs dissoluted from serum were developed by tetrahydrofuran-0.5% acetic acid (40:60), clofazimine and rifampicins could be analyzed separately. Apart from the mutual separation of water-soluble conjugates of DDS, the individual analysis of DDS, its main liposoluble metabolite and a few related sulfone compounds is possible when the drugs are first developed by acetonitrile-water (20:80). By the use of tetrahydrofuran-water (50:50) containing PIC B-5, the rapid measurement of clofazimine isolated from the other compounds is also possible.
