OBJECTIVE
To observe the efficacy and safety of zhongfu hypotension capsule (ZHC) in treating hypertension of yin-deficiency with sthenic-yang syndrome type.


METHODS
Adopting the stratified, block randomized, double-blinded, double-dummy, positive parallel controlled, multi-centered clinical trial method, the tested group was treated by orally taken 3 capsules of ZHC (0.5 g/capsule) twice a day, and the control group was treated by orally taken Lotensin Tablet 1 tablet (10 mg/tab.) once a day. And all received the adiaphorous drug with the dosage-form mimic to that used in the tested group. The therapeutic course was 4 weeks for both groups.


RESULTS
The markedly effective rate and the total effective rate in reducing blood pressure was 58.65% and 79.81% respectively in the tested group, and 60.51% and 78.34% respectively in the control group; while the markedly effective rate and the total effective rate for alleviating TCM syndrome was 21.15% and 78.85% in the tested group, and 25.48% and 86.62% in the control group respectively. Comparisons between the two groups showed insignificant difference (P > 0.05).
