Objective To investigate the pharmacokinetics of roxithromycin enterosoluble capsules in Chinese healthy volunteers.Methods 20 male healthy subjects received a single dose of 150 mg roxithromycin enterosoluble capsules.The serum concentration of roxithromycin was determined by LC-MS method.Results The main pharmacokinetic parameters of roxithromycin enterosoluble capsules were T_(1/2)(5.724±4.780) h,T_(max)(3.861±1.234) h,C_(max)(3.072±0.821)μg/ml,AUC_(0~48)(48.330±(16.649)) μgh/ml.Conclusion The pharmacokinetic parameters of roxithromycin enterosoluble capsules revealed the character of the dosage form.
