| Abstract: | Objective: To establish a method to determine doxofylline concentration in plasma by SEP-HPLC. Method: The doxofylline concentrations in plasma through solid-phase extraction were determined by HPLC method. Result: RSD of intra-day and inter-day were less than 10% the accuracy accorded with the plasma concentration monitoring and pharmacokinetic study. Conclusion: The SPE-HPLC method to determine doxofylline concentration is a ideal method. |
