A reversed-phase high performance liquid chromatographic method was developed for the simultaneous quantitative determination of caffeine, dapsone and chlorzoxazone. The operation was carried out on a C18 column (250 mm x 4.6 mm i.d., 5.0 microns) with the mobile phase of acetonitrile-phosphate buffer (including 0.02 mol/L KH2PO4 and 0.02 mol/L (C2H5)3N, pH 6.5) (25:75 in volume ratio). The eluate was detected at 265 nm in 0 min-12 min and at 280 nm in 12 min-25 min. Excellent linearity was observed over the effective concentration ranges in plasma. This method is simple, fast and can be applicable to clinical safe prescription.

UI	MeSH Term	Description	Entries

D002110	Caffeine	A methylxanthine naturally occurring in some beverages and also used as a pharmacological agent. Caffeine's most notable pharmacological effect is as a central nervous system stimulant, increasing alertness and producing agitation. It also relaxes SMOOTH MUSCLE, stimulates CARDIAC MUSCLE, stimulates DIURESIS, and appears to be useful in the treatment of some types of headache. Several cellular actions of caffeine have been observed, but it is not entirely clear how each contributes to its pharmacological profile. Among the most important are inhibition of cyclic nucleotide PHOSPHODIESTERASES, antagonism of ADENOSINE RECEPTORS, and modulation of intracellular calcium handling.	1,3,7-Trimethylxanthine,Caffedrine,Coffeinum N,Coffeinum Purrum,Dexitac,Durvitan,No Doz,Percoffedrinol N,Percutaféine,Quick-Pep,Vivarin,Quick Pep,QuickPep
D002753	Chlorzoxazone	A centrally acting central muscle relaxant with sedative properties. It is claimed to inhibit muscle spasm by exerting an effect primarily at the level of the spinal cord and subcortical areas of the brain.

D003622	Dapsone	A sulfone active against a wide range of bacteria but mainly employed for its actions against MYCOBACTERIUM LEPRAE. Its mechanism of action is probably similar to that of the SULFONAMIDES which involves inhibition of folic acid synthesis in susceptible organisms. It is also used with PYRIMETHAMINE in the treatment of malaria.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
