Uses for Papaverina

The main use for Papaverina is to treat vasospasms of the coronary arteries. It can also be used to treat obstructed arteries or to treat symptoms of anxiety and tension. Papaverina is occasionally used to treat impotence.

Mechanism of Action

Papaverina has a direct relaxant effect on the smooth muscle in the arterial walls, making it easier for the artery to expand. This, in turn, increases the amount of oxygenated blood that can flow through the coronary vessels, which decreases the symptoms of coronary artery vasospasms. Papaverina also affects the nerves, decreasing the intensity of signals that cause constriction.

It is important that the patient follows the doctor's instructions and takes the drug exactly as prescribed.
