Preliminary results of a small study may indicate that cholesterol-lowering statin drugs may help alleviate erectile dysfunction (ED) in men who have little reaction to Viagra.
Erectile dysfunction can be a sign of vascular problems and abnormalities in blood vessel linings. ED can therefore be an early sign of atherosclerosis, the build-up of plaque in the arteries.
Erectile dysfunction occurs because the body, in those circumstances, can no longer make enough nitric oxide.
Viagra allows the body to hold onto what little nitric oxide it manufactures in order to create an erection. Patients who did not respond to Viagra at first, but were given Lipitor and then Viagra again, reported some improvement.
The study was supported by an unrestricted medical center grant from Pfizer.
