OBJECTIVE: To evaluate the efficacy, safety and tolerance of Felodipine controlled release tablets and Felodipine controlled release tablets associated combination each with Metoprolol, Lisinopril or Hydrochlorothiazide in the 12 weekos treatment of mild to moderate essential hypertension in China. METHODS:Multicenter, random samples, and open study have been processed. RESULTS: (1)After 12 weekos associated combination treatment of antihypertension, the percentages of the persons who had attained the target were 80.2% of ITT group in Felodipine controlled release tablets associated combination with Hydrochlorothiazide, 74.1% of ITT group in with Metoprolol,and 80.5% of ITT group in with Lisinopril, respectively. (2)Mean reductions of systolic/diastolic blood pressure from baseline were 16.8/10.6 mm Hg in combination with Hydrochlorothiazide, 16.6/10.7 mm Hg in combination with Metoprolol,and 18.0/12.8 mm Hg in combination with Lisinopril each. There was no significant difference among these three groups (P>0.05). With the Felodipine controlled release tablets treatment alone, the mean reductions from baseline was 24.8/17.5 mm Hg. But in combination with Lisinopril, the blood pressure could lower more quickly, and then could reach the target more rapidly. (3)In the ITT group, the drug compliance with Felodipine controlled release tablets was 97.7%, with those in combination with Hydrochlorothiazide 89.8%, with those in combination with Metoprolol 100.0%, and with those in combination with Lisinopril 96.4%. The main adverse event related to Felodipine was headache, and to Lisinopril was cough. CONCLUSION: Antihypertensive drug Felodipine controlled release tablets are good and effective. And Felodipine controlled release tablet associated combination each with Metoprolol, Lisinopril or Hydrochlorothiazide can make most patients reach the treatment target, with safety, good tolerance, and high compliance.
