Viagra, or sildenafil citrate, primarily treats erectile dysfunction (ED), a condition affecting a man’s ability to achieve or maintain an erection firm enough for satisfactory sexual intercourse. It works by increasing blood flow to the penis.
How Viagra Works
Viagra enhances the effects of nitric oxide, a natural chemical in the body that relaxes blood vessels. This increased blood flow allows for easier erection upon sexual stimulation. It’s crucial to remember Viagra doesn’t cause erections without sexual stimulation.
Viagra’s Uses Beyond ED
While primarily used for ED, Viagra also finds application in treating pulmonary arterial hypertension (PAH), a condition involving high blood pressure in the arteries leading to the lungs. This use leverages Viagra’s blood vessel dilation properties to improve blood flow.
