No Metabolic Side Effects of Long-Term Treatment with Verapamil in Hypertension

Abstract

In a prospective, open study 45 patients (mean age fifty-three years) with essential hypertension were treated with verapamil for four to eight years (mean 5.3 years). Blood pressure was satisfactorily controlled (from 160/104 to 145/91) and the side effects were infrequent, mild, and often transient. Verapamil did not exert any unfavorable metabolic or hematologic effects over the years. HDL-cholesterol was moderately increased (mean 24%) and the other plasma lipids were unaffected. These data suggest that the calcium channel blocker verapamil is a metabolically safe drug to use as monotherapy in essential hypertension.
