      Abstract

      Minoxidil (2–4 diamino-6-piperidine-pyrimidine-5-oxide) is a directacting peripheral arteriolar vasodilator that reduces peripheral vascular resistance. It was first marketed by The Upjohn Company in 1979 as Loniten® Tablets for the treatment of severe hypertension. The peripheral vasodilation caused predictable cardiovascular effects, such as lowered blood pressure, reflex tachycardia, and fluid retention.1 Canine cardiac lesions were reported in toxicology studies, but no such findings are evident in humans.2
