Abstract
To compare pharmacokinetic behaviors of nitrendipine submicron emulsion with nitrendipine solution following intravenous administration in rats. The plasma concentrations were analyzed by ultra-performance liquid chromatography coupled with tandem mass spectrometry detection (UPLC-MS/MS) through a new validated method. The pharmacokinetic parameters of the nitrendipine submicron emulsion and nitrendipine solution were as follows: AUC0-t 900.76±186.59 versus 687.08±66.24ngh/ml, Cmax 854.54±159.48 versus 610.59±235.99ng/ml, t1/2 2.37±1.99 versus 2.80±2.69h. The relative bioavailability of nitrendipine submicron emulsion to nitrendipine solution was 131.4±11.3%. The developed methods could meet the requirements of bioanalysis. Compared to the solution injection, intravenous submicron emulsion presents higher systematic exposure which can help to improve the therapeutic efficacy.
