Comparative double-blind study of ketanserin versus propranolol in the treatment of essential hypertension.

To clarify the antihypertensive effect, safety and clinical usefulness of ketanserin, a comparative double-blind study was carried out in 277 patients with essential hypertension using propranolol as a control drug. Ketanserin 10 to 30 mg twice daily and propranolol 20 to 40 mg 3 times daily were administered for 12 weeks. The results showed no difference in antihypertensive effect and clinical usefulness between the drugs. In the ketanserine group, plasma concentration of total cholesterol was decreased significantly, and the reduction in heart rate was less than in the propranolol group. These findings suggest that ketanserin may satisfactorily control blood pressure.
