Abstract: AIM: To study the pharmacokinetics profiles of Ganyanling Zhusheye after single intramuscular dosing in healthy volunteers. METHODS: Twelve healthy vounlteers were given a single intramuscular dose of Ganyanling Zhusheye 2 mL. Matrine concentrations in plasma were determined by HPLC-MS-MS method.The pharmacokinetic parameters were obtained with statistical analysis by DAS Ver 2.0. RESULTS: Ganyanling Zhusheye disposition on intramuscular administration was characterized by a two-compartment pharmacokinetic mode. The mean pharmacokinetic parameters of healthy volunteers were t1/2z(7.5±1.4) h,CLz/F(17±4) L/h,tmax0.5(0.33,4) h,AUC0-t(2087±525) μg·L-1·h, AUC0-∞(2131±541) μg·L-1·h,Vz/F(185±47) L, Cmax (235±63) μg/L; The main pharmacokinetic parameters of rhein in female and male healthy volunteers were t1/2z (7.1±2.0) h vs(7.8±0.6)h, CLz/F(15±4)vs(20±3) L/h(P<0.05), tmax 0.75(0.33,4 ) vs 0.5(0.33, 1) h, AUC0-t (2396±524)vs(1816±322)μg·L-1·h (P<0.05), AUC0-∞(2456±549) vs(1778±322) μg·L-1·h (P<0.05), Vz/F(149±31)vs(222±27)L(P<0.05),Cmax(263±76) vs(208±31) μg/L. CONCLUSION: There is gender difference of pharmacokinetics of intramuscula Ganyanling Zhusheye in healthy volunteers.
