ABSTRACT
Aim To investigate the pharmacokinetics of intravenous injection of magnesium isoglycyrrhizinate in single dose in Chinese healthy volunteers.Methods 9 healthy volunteers received magnesium isoglycyrrhizinate injections in single dose of 100,200,300 mg respectively.The concentrations of magnesium isoglycyrrhizinate in plasma at different time were assayed with HPLC-UV method.The pharmacokinetic parameters of magnesium isoglycyrrhizinate injections were calculated with program 3P87.Results It was found that the plasma concentration-time curves of the preparetion fitted two-compartment model.The main pharmacokinetic parameters were as follows C_(max) were(28.79?3.54),(67.56?8.84) and(99.28?17.57) mg?L~(-1);T_(12?) were(1.72?0.27),(1.46?0.35) and(1.13?0.33) h;T_(12?)were(23.10?3.30),(23.95?4.72) and(24.25?4.12) h;V_d were(3.332?0.471),(2.921?0.382) and(2.921?0.622) L;CL were(0.209?0.041),(0.186?0.048) and(0.166?0.039) L?h~(-1);k_(10) were(0.063?0.012),(0.064?0.016) and(0.057?0.009) h~(-1);AUC_(0-72) were(448.68?75.06),(1015.29?225.14) and(1688.42?367.44) mg?h ?L~(-1).Conclusion The pharmacokinetics of the drug in the dosage range of 100~300 mg in human body approximately fit linear dynamic features.Compared with glycyrrhizic acid and other glycyrrhizinate salts,magnesium isoglycyrrhizinate is eliminated more slowly.This is beneficial to the treatment of chronic hepatitis.
