Viagra was originally investigated as a potential anti-angina medication, based on its ability to release nitric oxide and increase blood flow to the heart. Although Viagra failed as a heart medication, researchers in London became excited when many of the men in the clinical trials reported the frequent occurrence of unaccustomed erections and improved sexual performance. Following this serendipitous finding (and five years of clinical trials), Viagra was finally granted approval as a treatment for men suffering from difficulty in achieving erections due to conditions such as diabetes, vascular disease, spinal cord injury, and radical prostatectomy.

You may be wondering, How does Viagra work? Will it work for me? Unfortunately, as we age, cellular concentrations of cGMP decrease. Viagra works to achieve and maintain erections by (1) enhancing the effects of nitric oxide, and (2) maintaining higher levels of cGMP, the two key players in penile erection. The way Viagra does this is to selectively inhibit the cGMP-destroying actions of PDE-5. This in turn prevents relaxation of the smooth muscle in the corpus cavernosum, increases blood flow to the genitals, and leads to stronger erections and intensified sensation. All the technical jargon aside, You do have to be sexually stimulated in order to get and maintain an erection. It does not happen by the pill itself. Viagra can also take up to 30 minutes to activate, so relax and enjoy the time spent with your partner to get that erection going!

If this happens, and the erection lasts for more than 4 hours, you should go to the nearest emergency department. Prolonged erections can be dangerous. Viagra may not be safe to take for men with certain medical conditions, including men who have had a stroke, have heart disease or retinitis pigmentosa (an eye disease). It can also interact with many medicines, particularly nitrates and blood pressure medicines. Men who use nitrates in any form or are being treated for pulmonary hypertension should not take Viagra. All medicines have risks and benefits. Your doctor has weighed the risks of you taking Viagra against the benefits they expect it will have for you.
