Pinacidil is a vasodilator drug used to treat high blood pressure. It works by relaxing the blood vessels, allowing blood to flow more easily and reducing the pressure in the arteries. It is usually taken by mouth or applied topically to the skin. Side effects may include headache, nausea, dizziness, and a decrease in blood pressure.
Pinacidil was a medication used to treat high blood pressure (hypertension). It belonged to a class of drugs called potassium channel openers. Pinacidil worked by relaxing blood vessels, which lowered blood pressure.
The U.S. Food and Drug Administration (FDA) withdrew its approval of Pinacidil in 2008 due to safety concerns. There are other medications available to treat high blood pressure that are considered safer and more effective than Pinacidil.
