What are direct vasodilators?

Donna Hill Howes, RN
Family Practitioner

Direct vasodilators include the drugs minoxidil and hydralazine. These drugs relax the muscles in artery walls and allow blood to flow more freely. The drugs are sometimes prescribed for people who need a third drug to control severe high blood pressure. They are not used as first-line drugs because of their side effects.
