To compare the pharmacokinetics properties of enalapril-felodipine sustained-release tablet with enalapril and felodipine in the two reference formulations in Chinese healthy volunteers,the study was designed to a randomized, open label, crossover and two treatment pharmacokinetic study using enalapril-felodipine sustatined-release tablet as the test formulation. A total of 12 individuals were randomly assigned to 2 gorups (6 individuals in each group). The wash-out period was 14 d. Compared with the reference formulations, felodipine in the sustained-release tablet showed significantly sustained-release characteristics, while the pharmacokinetics processes of enalapril and its active metabolite enalaprilat were basically similar in Chinese healthy volunteers.
