What is Viagra?

Viagra, also known by its generic name sildenafil citrate, is a medication that works by increasing blood flow to the penis, thereby helping men to accomplish and maintain an erection during sexual stimulation. 비아그라 belongs to a class of medications referred to as phosphodiesterase type 5 (PDE5) inhibitors, which work by blocking an enzyme that may inhibit blood circulation to the penis.

How does it work?

When a man is sexually stimulated, the body releases nitric oxide, which in turn activates an enzyme called guanylate cyclase. This enzyme produces cyclic guanosine monophosphate (cGMP), which in turn causes the smooth muscles in the penis to relax and allows blood to flow in, resulting in an erection. However, an enzyme called PDE5 can breakdown cGMP and limit blood circulation to the penis, causing ED.

Viagra functions by inhibiting PDE5, which allows cGMP to build up and promotes blood flow to the penis. This results in an erection that is sufficient for sexual intercourse.
