Objective To study the pharmacokinetics profiles of ibupro-fen and pseudo ephedrine with chlorpheniramine suspension after single and multiple dosing in healthy volunteers.Methods Three single and one multiple oral doses of ibuprofen and pseudo ephedrine with chlorphe-niramine suspension were given to healthy volunteers respectively.Ibu-profen concentrations in plasma were determined by HPLC-UV method.Pseudo ephedrine and chlorpheniramine concentrations in plasma were determined by HPLC-MS-MS method.The pharmacokinetic parameters were obtained with statistical analysis by DAS Ver 2.0.Results The main pharmacokinetic parameters of 3 single doses(ibuprofen:200,400,600 mg pseudo ephedrine:30,60,90 mg;chlorpheniramine:2,4,6 mg)and multiple dose(ibuprofe,pseudo ephedrine and chlorphe-niramine 200,30,2 mg,respectively)shown that the concentration-time curves of ibuprofen,pseudo ephedrine and chlorpheniramine were described by one-compartment open model and physiological disposi-tions were assumed by linear kinetics characteristics.Conclusion In multiple dosing study,physiological dispositions of ibuprofen,pseudo e-phedrine and chlorpheniramine all existed no induction and inhibition of drug enzyme phenomenon.
