Regional Deficiencies in Blood Supply
Did you know that Viagra was actually under clinical trials for being a potential treatment for angina? The drug known then as UK-92,480 was under clinical supervision and the researchers found the test subjects reporting erections.
Intrigued by these reports. They launched a new study using a Rigiscan device to measure erections. These are loops placed over the erection to gauge how hard and erect the penis’s got during sexual stimulation.

Sildenafil (Viagra) is also marketed under the name Revatio for the treatment high blood pressure in the arteries of the lungs called pulmonary hypertension.
Sildenafil has also showed that men with angina can prolong their time exercising thus decreased the loss of muscle tissue. Could this suggest other uses for ED medication such as congestive heart failure, stroke, hypertension, and certain lung disorders?
Cedars-Sinai Medical Center researchers are currently testing Cialis (tadalafil), another erectile dysfunction drug, on men with Becker Muscular Dystrophy. This is one of the nine forms of muscular dystrophy, which is a group of muscle wasting diseases. Since tadalafil dilates blood vessels, and muscular dystrophy seems to be related to a lack of blood supply, the idea seems natural.
Dr. Ronald G. Victor of Cedars and his colleagues want to try this, which is being funded by the Muscular Dystrophy Association. They plan on testing 24 men with Becker’s, who will receive either a placebo or tadalafil, and then they will measure the amount of blood flow to the muscles while exercising.
This follows research on animal types of muscular dystrophy on mice. The research showed that the mice that had taken the drug could exercise much more vigorously with less muscle damage.
