RESUMEN
Objective To investigate the economic effects in patients with primary hypertension by four kinds of treatment.Methods 160 cases with primary hypertension were randomly divided into Benazepril group(n=40)、Perindopril group(n=40)、Amlodipine group(n=40) and Nitrendipine group(n=40),and data was evaluated with the pharmacoeconomic cost-effective analysis method.Results Hypertensive efficacy in 4 groups were not sig-nificantly different(x2=3.26,P>0.05);The symptom total score before treatment and after treatment was sisnifi-canfly different(a11 P<0.05);The SF-36 Scale after treatment in 4 groups were higher than before treatment(all P<0.05);The costs of pefindopril was lower than the benazepril.Conclusion Pharmacoeconomies played an important role in optimizing therapeutic scheme,guiding rational drug use and increasing economic effectiveness.
