Factors That Influence the Right Dosage for You

6.2 Postmarketing Experience
When you’re sexually aroused, your brain sends messages to your penis. These messages cause certain chemicals to be released in your penis. One of these chemicals, called cyclic GMP, relaxes and widens certain blood vessels in your penis. Cyclic GMP also relaxes the muscles around the erectile tissue in your penis that’s called the corpus cavernosum. These actions allow blood to flow into the corpus cavernosum, which causes your penis to get hard and become erect.
Viagra and foods
ED can occur if you have certain problems that affect your body’s ability to have an erection. The condition can result from problems with messages being sent from your brain. ED can also result from problems with blood flow into your penis. Viagra works to treat ED by helping you get and maintain an erection. The drug does this by improving blood flow into your penis when you’re sexually aroused.
Can Viagra be crushed, split, or chewed?
Viagra is a type of drug called a phosphodiesterase type 5 (PDE5) inhibitor. It works by inhibiting (blocking) the action of an enzyme called PDE5. (An enzyme is a protein that helps chemical reactions to happen inside your body.) Usually, an erection goes away when PDE5 breaks down the cyclic GMP in your penis. But Viagra blocks the action of PDE5, so it allows cyclic GMP to keep working for a longer period of time than usual. This action improves blood flow to your penis and helps you get and keep an erection. Headaches and sensitivity to light can also be improved by turning off any bright lights around you.
