Clinical study on the effectiveness and safety of terazosin in the treatment of benign prostatic hyperplasia patients with concomitant hypertension / 中国综合临床

ABSTRACT

Objective To evaluate the effectiveness and safety of terazosin in the treatment of benign prostatic hyperplasia (BPH)patients with concomitant hypertension.Methods A singlecenter prospective clinical observational study was conducted from March,2006 to March,2010 in our center.The main endpoints were the changes of IPSS total score,diastolic and systolic blood pressures at the end of 4 weeks and 3 monthes compared with the baseline,The second endpoints were Qmax value at the end of 4 weeks and 3 monthes compared with the baseline,Safety was assessed by adverse events.Results There were 212 patients in the study recruited,and 189 patients completed the study.All patients had BPH combined with hepertension.All patients were randomly devided into two statistical analysis group,blood pressure well controled and not well controled group,In the well controlled group,the IPSS socre reduced from 22.31 ± 5.18 at baseline to 15.64 ±3.91 at the end of the 4th weeks and 13.16 ± 3.53 at the end of 3rd monthes in the blood pressure well controled group populatin( P ＜ 0.01 ).The Qmax were improved significantly from (7.87 ± 2.41 ) ％ at baseline to (14.19 ±2.64)％ at the end of the 4th weeks and (15.69 ±2.77)％ at the end of3rd monthes in the blood pressure well controled group populatin( P ＜ 0.01 ).Terazosin had moderate effect in blood pressure decreasing (P ＜ 0.05 ),and all patients were within normal blood pressure range.In the uncontrolled group,the IPSS socre reduced from 21.55 ± 4.82 at baseline to 15.44 ± 3.66 at the end of the 4th weeks and 12.96 ± 3.11 at the end of 3rd monthes in the blood pressure well controled group populatin (P ＜ 0.01 ).The Qmax were improved significantly from ( 8.27 ± 2.27 ) ％ at baseline to ( 14.26 ± 2.87) ％ at the end of the 4th weeks and ( 15.51 ±2.92) ％ at the end of 3rd monthes in the blood pressure well controled group populatin( P ＜ 0.01 ).Terazosin decreased BPH patient blood pressure with controlled patients and unctrolled patients additionaly to other blood pressure medicine (P ＜ 0.05 ),and no severe side effect occured.At the end of the study,all patients were taking drug continuously and were followed.Conclnsion Terazosin can significantly improve the symptoms and quality of life in BPH patients with hypertension with good safety and compliance.
