Abstract Objective: To establish an LC-MS/MS method for the determination of carbazochrome sodium sulfonate in human plasma and study its ics. Methods: A single oral dose of 90 mg carbazochrome sodium sulfonate capsules was given to each of 24 Chinese healthy volunteers. Blood samples were collected before and ,,,,,,,,,, ,
, h after the administration. The drug plasma concentrations were determined by a validated LC-MS/MS method in APCI positive ion mode. Results: The calibration curve of the LC-MS/MS method was linear in the range of ng·mL-1-50 ng·mL-1 with the accuracy from 90% to 105%. The intra-day and inter-day precession (RSD) were %-% and %-%, respectively. The main ic parameters of carbazochrome sodium sulfonate after a single oral dose 90mg were as follows, Cmax (± ) ng∙mL-1,Tmax ( ± ) h,t1/2 (± ) h,MRT ( ± ) h,AUC0-8 ( ± ) h·ng∙mL-1,AUC0-¥ ( ±) h·ng∙mL-1,Vz/F (± ) L,CL/F ( ±
