Abstract: In order to compare the concentration of each component of Sukang detoxification oral liquid in rat plasma after administrated by oral and intramuscular, and ascertain pharmacokinetic characteristics of Sukang detoxification oral liquid in trials rats, 28 rats were randomly divided into seven groups, using UV spectrophotometry to measure plasma concentration of each component at different times after administrated by oral and intramuscular, calculated pharmacokinetics parameters of various components of detoxification agent. The results showed that plasma concentration-time process of each component of detoxification agent in rats could be described as two-compartment model tools with absorption. After oral administration the maximum plasma concentrations of each component were sodium 8039.455 μg/mL, yeast mannan 129.932 μg/mL, magnesium 3358.328 μg/mL, rhamnose 2296.330 μg/mL.Tp(h) by oral administration of sodium,sulfate,yeast mannan,L-rhamnose were 1.2816,1.4201,1.1337,0.9469 h;by intramuscular administration they were 1.2856,1.4684,1.1079,1.1671 h. Experimental studies had shown that each component of Sukang detoxification oral liquid was quickly absorbed into the blood after administration, there was little difference between oral and intramuscular administrations,but oral administration had long function and more convenient on administration than intramuscular.
