Older men like Playboy’s Hugh Hefner and actor Michael Douglas have sung the praises of Viagra, but now scientists say the erectile dysfunction pill is not only good for your sex life — it’s good for your heart. In the bedroom, Viagra allows greater blood flow to the penis. But in the heart, the “little blue pill” can prevent heart muscle thickening and early-stage heart failure, according to research published today in the open access journal BMC Medicine."Large clinical trials are now urgently needed to build on these encouraging findings,” said lead author Dr. Isidori, associate professor of endocrinology at Sapienza University of Rome. Dosages used for heart ailments are lower than those used for erectile dysfunction, and patients in the study showed few side effects. “Surprisingly, in over 1600 treated subjects, no increased risk of visual disturbance, photosensitivity and ‘blue haze,’ was observed,” he told NBC News. The active ingredient in Viagra is sildenafil citrate, which is a phosphodiesterase type 5 inhibitor (PDE5i). The inhibitor blocks the enzyme PDE5, which prevents relaxation of smooth muscle tissue.

    A normal male erection can occur when physical or psychological stimulation triggers impulses from the brain to travel down to the nerves of the penis. These signals cause the muscles within the arteries to relax, making the arteries bigger, and resulting in more bloodflow through the penis. Sometimes physical causes such as disease or injury can prevent the signals from reaching the arteries. Erectile dysfunction can be treated with a medication called sildenafil citrate. This medication blocks the effects of an enzyme, causing the smooth muscle in the walls of the arteries to relax. The arteries grow in size to allow more blood to flow through the penis. At the same time, the enlarged arteries put pressure on nearby veins, which prevents blood from exiting and maintains an erection. The effects of sildenafil citrate are only temporary, and can not be considered a permanent cure for erectile dysfunction. Sildenafil relaxes muscles of the blood vessels and increases blood flow to particular areas of the body. Sildenafil under the name Viagra is used to treat erectile dysfunction (impotence) in men. Another brand of sildenafil is Revatio, which is used to treat pulmonary arterial hypertension and improve exercise capacity in men and women. Do not take sildenafil if you are also using a nitrate drug for chest pain or heart problems, including nitroglycerin, isosorbide dinitrate, isosorbide mononitrate, and some recreational drugs such as "poppers". Taking sildenafil with a nitrate medicine can cause a sudden and serious decrease in blood pressure. Some medicines can cause unwanted or dangerous effects when used with sildenafil. Tell your doctor about all your current medicines, especially riociguat (Adempas). Contact your doctor or seek emergency medical attention if your erection is painful or lasts longer than 4 hours. A prolonged erection (priapism) can damage the penis.
