Abstract:
AIM: To study chronopharmacokinetics of helicid and its metabolites. METHODS: An HPLC-MS method for simultaneous determination of helicid and its three phase I metabolites were established and validated. At 8:00, 14:00 and 0:00, the rats were given helicid 50 mg/kg by gavage, respectively. Blood samples were collected from ophthalmic venous plexus. Then plasma concentration was measured. Pharmacokinetic behaviors of the original drug and its metabolites after administration at different time points were calculated and compared. RESULTS: This established HPLC-MS/MS method was successfully applied to simultaneous determination of helicid and its three metabolites in rat plasma after intragastric administration. Using AUC
