Topic: SILDENAFIL — Description
Sildenafil, or what is popularly known as the brand name Viagra, is a drug classified as phosphodiesterase (PDE) inhibitors. This drug is primarily used to treat patients with erectile dysfunction or those who are having difficulty in maintaining an erection. This drug works by increasing the flow of blood towards the penis which will then aid in keeping the erection.
Another use of Sildenafil that is not as popular as its use for ED, is its benefit for those suffering from Pulmonary Arterial Hypertension (PAH). People with PAH experiences tiredness, dizziness, and shortness of breath because there is an elevated blood pressure in the vessels transporting blood to the lungs. With the help of sildenafil, the blood vessels in the lungs relaxes and widens, causing the blood to flow more efficiently. People with PAH who would prefer to exercise regularly to improve their health may do so with the assistance of this medication.
