Viagra, Cialis, Levitra, and generic sildenafil are all part of a family of drugs called PDE-5 inhibitors. These drugs are used to treat erectile dysfunction (ED).

The other main difference is that generic sildenafil is FDA approved to treat Pulmonary Hypertension (that’s high blood pressure between the heart and lungs) while Viagra is FDA approved to treat erectile dysfunction. It’s a little confusing since both medications use the same active ingredient, but Viagra and sildenafil work in the same way. Sildenafil works by helping more blood get into your penis when you are sexually aroused. An erection is produced via a complex chain of events, involving signals from the nervous system and the release of chemical messengers within the tissues of the penis. One of the messengers released when you are aroused is called cyclic GMP. Cyclic GMP relaxes and widens the blood vessels in the penis, allowing more blood to enter. Cyclic GMP is normally broken down by an enzyme in the body called phosphodiesterase type 5 (PDE5). Sildenafil is a type of medicine called a PDE5 inhibitor. It works by stopping this enzyme from breaking down the cyclic GMP. This allows the blood vessels in the penis to stay dilated for longer, which improves blood flow to the penis and helps produce and maintain an erection.
