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.
