Description
Viagra is a brand-name version of the generic drug sildenafil. It’s a phosphodiesterase type 5 (PDE5) inhibitor. PDE5 is an enzyme that regulates certain chemicals in your blood, but as a result, it can make it harder for you to get and keep an erection.
Viagra is used to treat erectile dysfunction (ED). While it helps you temporarily maintain an erection so you can have sex, it doesn’t cure ED. It doesn’t affect sexual desire either. You still need mental or physical stimulation to get an erection.
Viagra is a powerful drug that increases blood flow to the penis so you can get and maintain an erection.
