For patients dealing with erectile dysfunction (ED), certain medications that enhance the effect of nitric oxide, a natural chemical your body produces to relax muscles in the penis and increase blood flow, can help in managing symptoms. Levitra and Viagra are two such drugs commonly prescribed for ED.
Key takeaways
Vardenafil can be affected by high-fat foods. However, based on clinical studies, changes in food intake are not required. The prescribing information says that Vardenafil can be administered with or without meals. Conversely, Sildenafil can also be consumed with or without food. However, taking this PDE5 inhibitor with a high-fat meal can make the medicine take about an hour longer to show its effects.

Levitra, also known as vardenafil, tends to be less affected by food or alcohol consumption and so provides more flexibility with meal choices prior to its use. Viagra, on the other hand, is generally recommended to be taken on an empty stomach for optimal absorption into the bloodstream. Both these drugs require sexual stimulation to activate their function effectively. Vardenafil (the generic name for Levitra) was a significant development in the class of PDE5 inhibitors used to treat erectile dysfunction, following the first drug of this type known as sildenafil or Viagra.
Drug and food/lifestyle interactions
Few research studies have compared Sildenafil and Vardenafil. One study by Sheila A. Doggrell, published in 2005, compared three erectile dysfunction medications: Sildenafil, Vardenafil, and Tadalafil. The study found that Vardenafil was stronger than Sildenafil. However, both medications were found to be effective similarly in treating erectile dysfunction.

Another study concluded that both Sildenafil and Vardenafil were well-tolerated, with Vardenafil performing better than Sildenafil [6]. Overall, both drugs are generally effective for treating impotence. The American Urological Association does not recommend any specific option over another best viagra for men as long as it is appropriate for the individual. Doctors also recommend other treatment options for ED, such as surgery, making lifestyle changes, and seeing mental health professionals. Lifestyle changes that may help treat ED include exercises for ED and dietary changes.
Are vardenafil and sildenafil available over the counter?
Vardenafil and Sildenafil are commonly prescribed medications used to treat impotence. They can help with maintaining and achieving an erection in combination with sexual stimulation. Both of these medications are part of a class of drugs called PDE5 inhibitors. PDE5 inhibitors work by increasing blood flow to the penis. Because they are in the same drug class, they have many similarities but also some differences. Vardenafil was approved by the FDA in 2003, several years after Viagra's initial approval in 1998.
- Use Vardenafil 20mg only as prescribed; misuse may lead to health risks.
- Do not take more than once a day to prevent overdose.
- Combine with other ED treatments only under medical advice.
Levitra works by increasing blood flow to the penis upon sexual stimulation by inhibiting enzyme phosphodiesterase-PDE5 in smooth muscle cells lining the blood vessels supplying corpus cavernosum of the penis.

It is prescribed for men with problems achieving and maintaining an erection, essentially aiding them to perform better sexually. Though similar to Viagra's mechanism of action, Levitra has a more selective influence on Phosphodiesterase-5 (PDE-5), resulting in fewer side effects related to vasodilation than some other drugs used for erectile dysfunction that have stronger effects on multiple phosphodiesterases.

Levitra is approved for the treatment of erectile dysfunction (ED) and can help men with ED get and keep an erection satisfactory for sexual activity. Once a man has completed sexual activity, blood flow to his penis decreases, and his erection goes away: Erectile Dysfunction: Levitra increases blood flow to the penis helping achieve an erection Premature Ejaculation: Some studies suggest it may help in delaying ejaculation although not specifically licensed for this use. Levitra manages erectile dysfunction by increasing the amount of nitric oxide available in the blood vessels of the penis. It accomplishes this by blocking PDE5, an enzyme that breaks down cGMP, a chemical that relaxes smooth muscles and increases blood flow to facilitate an erection. Nitric oxide is a vasodilator, meaning it helps expand blood vessels to increase blood flow throughout the body and plays an important role in sexual arousal and response. Men with erectile dysfunction often have lower levels of cGMP due to overproduction of PDE5. Therefore, by inhibiting PDE5, Levitra can enhance the effects of nitric oxide, improve blood flow to the penis and help patients manage their condition while improving sexual performance. Viagra is the brand name for sildenafil, an inhibitor of phosphodiesterase-5 (PDE5), which effectively increases blood flow to certain parts of the body by relaxing muscles in the walls of blood vessels.
- Consult your doctor if you experience persistent erection issues.
- Do not share medication with others; it is prescribed for individual use.
- Regular check-ups are recommended for ongoing use.
It was first approved by the FDA in 1998 as a treatment for erectile dysfunction.

Some popular generic versions of Sildenafil include Aurogra 100 mg, Cenforce Professional, Viagra, and Cenforce 100 mg. Apart from these dosage strengths of the generic versions of Sildenafil, higher dosage strengths of this drug are also available, such as Cenforce 150 and 200 mg and Malegra 200 mg. Vardenafil is also sold under various generic and brand names, such as Vitara V 60 mg, Vilitra 20 mg, Vilitra 40 mg, and Levitra.

The increased flow of blood to the penis can lead to an erection.
Viagra™ Efficacy
It is crucial to remember that these medications do not cure ED, and they also do not prevent STIs (sexually transmitted infections) or pregnancy [2] [3]. To get effective results, follow all the instructions on your medication’s label for taking it. Generally, Sildenafil and Vardenafil have similar recommendations for how to consume them, which are as follows: Vardenafil and Sildenafil should be taken about 60 minutes before sexual intercourse for optimal response. However, Sildenafil can be taken anywhere between half an hour and up to four hours before sex. Do not consume more than one tablet in a 24-hour period. Unlike vardenafil (the active ingredient in Levitra), sildenafil does not have an effect on other types of phosphodiesterases, making its action more specific and targeted. This selectivity means that Viagra's side-effect profile can be slightly different than that of Levitra, particularly regarding potential vision issues related to PDE6 inhibition (a known side effect with non-selective PDE inhibitors like Levitra).

The benefits on increased blood flow make Viagra a go-to treatment for patients suffering from erectile dysfunction who may not respond well to other treatments or therapies. Viagra, also known by its generic name sildenafil, is approved for the treatment of: Erectile dysfunction (ED), a condition where a man has difficulty achieving or maintaining an erection suitable for sexual intercourse Pulmonary arterial hypertension (PAH), a type of high blood pressure that affects the arteries in the lungs and right side of your heart. Nitric oxide is a molecule that plays key roles in many biological processes, including blood vessel dilation, immune response, and neurotransmission. In relation to erectile function, it plays a major role by stimulating the production of cyclic guanosine monophosphate (cGMP), which relaxes smooth muscle cells in the penis allowing more blood flow. A lack of nitric oxide can contribute to erectile dysfunction. Viagra works primarily by inhibiting an enzyme called PDE5 that breaks down cGMP in the penis thereby increasing its levels resulting in improved erectile function.
