Other uses of viagra - Pulmonary hypertension
Everyone aware that viagra is for treating erectile dysfunction. There are many jokes and over expectation out of it.
If we turn back the history of viagra research, it was developed to lower blood pressure and treat angina. But the researchers found the male erection as the side effect of using sildenafil. So the pharmaceutical giant Pfizer found a new product for erectile dysfunction and released the product viagra, i.e, the same sildenafil after a lot of clinical and safety tests.
Eversince viagra is known for traeting erectile dysfunction only. But the pathway of its action is blocking an enzyme called phospodiesterase type 5 - PDE5. By doing this it increases the blood flow to the penis.So it is concluded as a potent vasodilator which can be used to relax the blood vessels in other parts of the body say heart and lungs.
So doctors now opine that it is a good drug for lowering blood pressure and cordiac conditions. But doctors are warning not to take viagra along with nitrates which is used for chest pain or angina, because it could lead to dangerously low blood pressure which may be even fatal.
Since erectile dysfunction and coriovascular diseases have some thing in common, patients prescribed with viagra for heart condition, it improves the heart condition as well as erectile function.
So now scientists are of the opinion that viagra may be used to treat many other medical conditions like pulmonary hypertension. There is even incidents like doctors used viagra to save premature babies with breathing problems with highly fatal conditions.

Viagra and high blood pressure
Erectile dysfunction is very common in the men with illness of heart and hypertension, and while it is often put the responsibility on the medicines, most of the time, it is due to illness of the arteries that provide the penis that is affected elsewhere of the same way as arteries in the body. Viagra (sildenafil) helps to dilate the arteries in the penis and to encourage the current of blood in him that is required to produce erection. In people without illness of the arteries, Viagra dilates some of the other arteries of it in the body to a small extent and decrease blodd pressure by some points. It potentiates the effects of nitroglycerine that also dilates some arteries and is used to treat the angina. It can result in a bigger and sudden fall of tension that could be serious in someone that has the illness of heart. Viagra should not be used ever therefore by people who take nitroglycerine or related drugs (nitrates) to treat their angina. There were some reports of the case of men that have some heart attacks after having taken Viagra, but these were probably of pure coincidence and not the result to take the Viagra.
