What is Papaverine?

Papaverine is a vasodilator, a medication that relaxes the smooth muscles in your blood vessels, causing them to widen. This action decreases blood pressure and facilitates blood flow into veins and arteries.

It is an alkaloid found in opium but is structurally and pharmacologically distinct from other opium alkaloids. Papaverine acts as a smooth muscle relaxant and is used to treat conditions such as impotence and as a vasodilator, particularly for cerebral vasodilation.

Papaverine Uses

Papaverine is used to treat various disorders that cause smooth muscle spasms, including chest pain, circulation issues, heart attacks, and stomach or gallbladder problems. It improves blood flow by relaxing blood vessels, thus enhancing blood supply to the heart and throughout the body. Although previously used for erectile dysfunction, it is no longer recommended for this purpose due to the risk of painful or prolonged erections.

Note: Papaverine injections should only be administered by a healthcare professional and should not be self-administered. Long-term use can lead to dependency and should be managed under strict medical supervision.

Missing one or two doses of Papaverine usually does not cause harm. However, for the medication to be effective, take it as prescribed. If you miss a dose, take it as soon as possible, but do not double the dose to make up for the missed one.
