Efficacy of Qianyangxifeng capsule for treating primary hypertension with yin deficiency and yang excess

Objective To observe clinical effect and safety of Qianyangxifeng capsule for treating primary hypertension with yin deficiency and yang excess,and explore the correlation of primary hypertension and yin deficiency and yang excess.Methods 120 cases of primary hypertension were randomly divided into two groups,treatment group.60 cases in control group were given benazepril 10mg.60 patients in treatment groups were treated by Qianyangxifeng capsule.The course was two months in two groups.Blood pressure and traditional Chinese medicine syndrome were observed in the two groups before and after treatment.Results Blood pressure comparison:,blood pressure after treatment decreased significantly as compared with that before treatment in two groups(P0.05),there was no significant difference between two groups(P0.05).Hypotensive effect: the total effective rates of the antihypertensive efficacy in treatment group(93.3%) was similar to that in control group(90.0%,P0.05).Improvement in the traditional Chinese medicine syndrome,the total effective rate in the treatment group(91.7%) was higher than that in control group(68.3%,P0.05).Conclusion Qianyangxifeng capsule and benazepril is equivalent on antihypertensive effects,but Qianyangxifeng capsule is superior to benazepril in the improvement in the traditional Chinese medicine syndrome.Pathogenesis of yin deficiency and yang excess is the most basic pathogenesis of hypertension in traditional Chinese medicine.
