Sildenafil (Brand names: Viagra, Revatio, Caverta, Penegra) is generally prescribed to treat men with erection problems. It is also used to treat pulmonary arterial hypertension (PAH) (i.e. high blood pressure in your lungs). Sildenafil works on erection problems by increasing blood flow to the penis.
Sildenafil works for PAH by relaxing your lungs’ blood vessels, allowing blood to flow easier. People can save money on sildenafil 50 mg by comparing sildenafil prices at Canadian and international online pharmacies with discount prices available at U.S. pharmacies. Purchasing higher quantities usually means lower prices. Sildenafil sold in the U.S. is manufactured in several countries, including India and Ireland.
