Vasodilators for ED are medications that help widen blood vessels, improving blood flow throughout the body. When used for erectile dysfunction (ED), vasodilators work by increasing blood flow to the penis, which can help men achieve and maintain an erection during sexual activity. Erectile dysfunction is often caused by insufficient blood flow to the penis, and vasodilators address this underlying issue by relaxing the smooth muscles of blood vessels. PDE5 inhibitors are a type of vasodilator commonly prescribed for ED.
