Simultaneous liquid-chromatographic determination of carbamazepine and its epoxide metabolite in plasma.
We describe a liquid-chromatographic method for the simultaneous quantification of carbamazepine and its 10,11-epoxide metabolite in plasma. The method is used routinely in the analysis of carbamazepine and its epoxide in 0.5 mL of plasma at concentrations of 1 to 20 and 0.2 to 5 mg/L, respectively. The use of peak-height ratios as a measure of detector response appeared to provide better preci...
متن کاملSCN1A and SCN1B gene polymorphisms and their association with plasma concentrations of carbamazepine and carbamazepine 10, 11 epoxide in Iranian epileptic patients
Objective (s): From a genetic point of view, epilepsy is a polygenic multifactorial syndrome. The SCN1A and B genes belong to a family of genes that provide instructions for making sodium channels. Understanding the relevance of SCN1A and SCN1B gene polymorphisms to plasma concentration of carbamazepine (CBZ) and its active metabolite carbamazepine 10, 11 epoxide (CBZE), may shed more light on ...
متن کاملSimultaneous determination of carbamazepine and its epoxide and transdiol metabolites in plasma by microbore liquid chromatography.
Simultaneous monitoring of carbamazepine and its metabolities is helpful in providing information on the induction process via the epoxide-diol route. The present method involves the liquid-chromatographic analysis of 1.0 mL of plasma for carbamazepine at concentrations of 0.025 to 4.0 mg/L and for both the 10,11-epoxide and 10,11-transdiol metabolites at concentrations of 0.01 to 1.0 mg/L. Wei...
متن کاملPreparation of a Major Metabolite of Iguratimod and Simultaneous Assay of Iguratimod and Its Metabolite by HPLC in Rat Plasma
Iguratimod is a new synthetic disease-modifying antirheumatic drug intended to treat patients with rheumatoid arthritis. A new method using recombinant human CYP450s yeast cells containing c-DNA expressed P450s was applied to identify the metabolic pathways of iguratimod and to prepare its metabolite. The metabolite was isolated, and its structure was identified by quadrupole time-of-flight-mas...
