Abstract:Objective: To establish a HPLC-MS-MS determination method of artemether (ARM) and active derivatives DHA, and compare the pharmacokinetic parameters of ARM after transdermal and oral administration. Method: The mice were divided two groups (transdermal and oral) by parallel design. ARM and active derivatives DHA in plasma of mice at different sampling time were determined. The pharmacokinetic parameters were calculated by DAS 2.0 and by statistic analysis. Result:compare oral administration, the pharmacokinetic parameters of ARM after transdermal, Cmax, Tmax, AUC0~t, MRT, had significant difference (P<0.05). Conclusion: The artemrther patch has long-releasing property.
