What is Viagra?

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

So how exactly does it work?

Whenever a man is sexually stimulated, your body releases nitric oxide, which 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 flow to the penis, causing ED.

Viagra functions by inhibiting PDE5, which allows cGMP to accumulate and promotes blood flow to the penis. This leads to an erection that’s sufficient for sexual activity.
