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. No, Viagra doesn’t directly increase your sex drive. But if you feel anxious, nervous, depressed, or stressed, your body may not respond well to sexual stimulation. If this is the case, try to relax, make yourself comfortable, and take your time. In addition, if you drink alcohol, it’s best to avoid drinking a lot of it.
