Analyzing the Chemical Composition of Generic Vardenafil Tablets
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.

Levitra is only slightly affected by food, meaning you can take it with a meal without any significant loss of effectiveness. In contrast, Viagra might take longer to work if it’s taken with a large, high-fat meal. Overall, there’s no “best” erectile dysfunction medication for everyone. You’ll usually get the best results by working with your healthcare provider to choose the medication that’s best suited to your needs and preferences. 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.
Can you mix Viagra with Levitra?
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. Vardenafil, on the other hand, is used exclusively to treat ED and is not marketed or used as a treatment for any form of hypertension. Levitra and Viagra both last for a similar amount of time inside the body. Both medications are intended to provide short-term relief from erectile dysfunction, usually for a few hours of sexual activity.

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. Levitra and Viagra are both very effective at treating erectile dysfunction.
