Viagra is a powerful drug that increases blood flow to the penis so that you can get and maintain an erection. It is effective, but it can also cause some side effects.
Viagra is the brand name for generic sildenafil. It is a phosphodiesterase type 5 (PDE5) inhibitor. PDE5 is an enzyme that regulates certain chemicals in the blood, but its effects on the body can make it difficult for the organ to acquire and maintain it.
Viagra is used to treat erectile dysfunction (ED). Although it helps temporarily maintain an erection so you can have sex, it does not cure erectile dysfunction. It also does not affect sex drive. You still need mental or physical stimulation to get an erection (See More....)
