Objective To observe the effect of irbesartan combined with levoamledipine in patients with hypertension and proteinuria. Methods Ninety patients with hypertension and proteinuria were randomly divided into two groups. Group A of 46 patients received irbesartan 150 mg po qd and levoamlodipine 2. 5 mg po qd,Group B of 46 patients received levoamlodipine 2. 5 mg po qd and hydrochlorthiazide 12. 5 mg po qd for 6 months. Blood pressure( BP),24 h urinary albumin were measured before and after treatment. Results After 6 months,both of two groups can efficiently reduce blood pressure,proteinuria. In contrast,the proteinuria in group A was significantly reduced than that of group B after treatment. Conclusion Irbesartan combined with levoamlodipine can remarkably decrease BP and proteinuria and better protect renal function.
