VIAGRA: MECHANISM AND SIDE EFFECTS

erectile dysfunction

Viagra is a brand name for the generic drug sildenafil. It’s a phosphodiesterase type 5 (PDE-5) inhibitor. PDE-5 is an enzyme that can stop you from having an erection.This medication is used to treat erectile dysfunction (ED). While it helps you temporarily maintain an erection so you can have sex, it does not cure ED. Also, it does not affect sexual desire. You still need mental or physical stimulation to get an erection.

CIRCULATORY SYSTEM 

Beginning with arousal signals from your brain, it takes a finely choreographed series of events to produce an erection. And it all hinges on good blood flow to the penis.

Within the penis are two chambers called the corpora cavernosa. Nitric oxide (NO) is released in the chambers during sexual stimulation. NO activates an enzyme called guanylate cyclase. That increases levels of cyclic guanosine monophosphate (cGMP), which causes muscles to relax.

The chambers also contain a network of blood vessels. When those blood vessels relax and widen, blood rushes in. The resulting pressure is what causes an erection.

PDE-5 can dampen the effect of cGMP. Viagra works by inhibiting PDE-5.
