Antihypertensive Effect of Bunazosin(Detantol®) in Essential Hypertension

Antihypertensive effect of Bunazosin was evaluated in 23 patients with essential hypertension. Systolic blood pressure decreased from 175.5±16.9mmHg to 167.5±30.2mmHg after 4 weeks and to 165.4±29.7mmHg(p<0.05) after 8 weeks of medication. Diastolic blood pressure decreased from 105.6±9.7mmHg to 98.6±11.6mmHg(p<0.05) after 4 weeks and to 98.1±12.2mmHg(p<0.05) after 8 weeks of medication. Heart rate and serum lipid profiles did not change significantly. Transient side effects such as nausea(two cases), headache (one case), and weakness(one case) were observed, but there were no significant side effects. Therefore Bunazosin seemed to be effective in lowering blood pressure without reflx tachycardia, changes of serum lipie profiles, and significant side effects.
