Below, we’ve listed the main differences between Levitra and Viagra, from the best time to take each medication before sex to the different amounts of time that Levitra and Viagra will improve your sexual performance and provide relief from erectile dysfunction.
How Levitra and Viagra Work
Before we go into more detail about the key differences between Levitra and Viagra, let’s briefly go over how both of these medications work.

Levitra, which contains vardenafil, and Viagra, which contains sildenafil, both belong to a class of medications referred to as PDE5 inhibitors.

As their name suggests, PDE5 inhibitors work by inhibiting the effects of the PDE5 enzyme, or phosphodiesterase-5. This enzyme is found in the smooth muscle cells of your blood vessels, where it’s involved in regulating blood flow.

Healthy erections are all about steady, consistent blood flow. When you feel sexually aroused, your nervous system causes the muscles in your penis to relax, increasing the flow of blood to the corpora cavernosa -- a pair of sponge-like chambers of tissue inside your penis.

This process usually begins in response to sexual stimulation, such as being touched by your partner or seeing sexual imagery.

As more blood flows to the corpora cavernosa, your penis becomes larger and firmer, creating an erection. A fibrous membrane called the tunica albuginea wraps around this tissue, helping you to maintain your erection during sexual intercourse.

After you reach orgasm and ejaculate, blood flows out from this tissue and your penis starts to become flaccid once again.

A range of issues can cause erectile dysfunction, but many cases of ED are caused by health issues that affect blood flow to your penis.

As PDE5 inhibitors, Levitra and Viagra increase the diameter of the blood vessels that supply your penis and improve blood flow, making it easier for you to get a penile erection.

The active ingredient in Levitra is called vardenafil. Under the brand name Levitra, vardenafil was approved by the FDA in 2003 as an erectile dysfunction medication. This makes Levitra the newer of the two drugs.

The active ingredient in Viagra is called sildenafil. As Viagra, sildenafil received approval from the FDA in 1998, making it the oldest oral medication that’s currently available to treat erectile dysfunction.

Because of its effects on arterial blood flow, sildenafil is also used as a treatment for pulmonary hypertension, a form of high blood pressure that affects the lungs.
