Viagra or sildenafil is a medicine that is used for treating male sexual dysfunction. The main function of Viagra is to increase the blood flow in the body, specifically to the penis, for an erection. It works by blocking an enzyme called PDE5, which hinders blood flow in the penis.
Viagra belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. It works by inhibiting the enzyme PDE5, which regulates blood flow in the penis. By doing so, it allows the blood vessels in the penis to relax and expand, facilitating an erection when sexually stimulated.
Viagra is a medication used to treat erectile dysfunction (ED) in men. ED is a condition where a male fails to get or maintain an erection while having sexual intercourse. The medicine stimulates sexual functions by increasing the flow of blood to the penis and helps in proper and quick erection.
Some of the Viagra tablet uses are for treating:
Low Sexual Desire
Impotence
Pulmonary Arterial Hypertension
Raynaud’s Phenomenon
