There are a few side effects experienced with vardenafil.

Talk to your care team if you have concerns about these side effects.

Do not take a higher dose of vardenafil than your provider orders for you.

Headache, facial flushing, stuffy or runny nose, and upset stomach can occur. Less frequent side effects online ed drug include blurry vision, a bluish hue to the field of vision, difficulty telling the difference between the colors blue and green, a sensitivity to light, or a sudden loss of vision or hearing. If you experience any of the following while using vardenafil, seek immediate medical attention: An erection lasting more than 4 hours.

Chest, arm or neck pain, or nausea during sexual activity.

Remember, vardenafil does not protect against sexually transmitted diseases, nor does it prevent pregnancy.

Effective birth control is recommended during cancer treatment.

Even if you are not producing sperm, you could still be fertile and conceive. Vardenafil (Levitra) is an oral therapy for the treatment of erectile dysfunction. It is a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5).

Penile erection is a hemodynamic process initiated by the relaxation of smooth muscle in the corpus cavernosum and its associated arterioles.

During sexual stimulation, nitric oxide is released from nerve endings and endothelial cells in the corpus cavernosum.

Nitric oxide activates the enzyme guanylate cyclase resulting in increased synthesis of cyclic

guanosine

monophosphate

The tissue concentration of cGMP is regulated by both the rates of synthesis and degradation via phosphodiesterases (PDEs).

The most abundant PDE in the human corpus cavernosum is the cGMPspecific phosphodiesterase type 5 (PDE5); therefore, the inhibition of PDE5 enhances erectile function by increasing the amount of cGMP. BAY 389456 BAY-389456 BAY38-9456 DE 19750085 1997 WO 99/24433 1999.

Vardenafil is online ed drug used to treat male erectile dysfunction (impotence) and online ed drug pulmonary arterial hypertension (PAH). Part of the physiological process of erection involves the release of nitric oxide (NO) in the corpus cavernosum.

This then activates the enzyme guanylate cyclase which results in increased levels of cyclic guanosine monophosphate (cGMP), leading to smooth muscle relaxation in the corpus cavernosum, resulting in increased inflow of blood and an erection. Vardenafil is a potent and selective inhibitor of cGMP specific phosphodiesterase type sildenafil citrate online pharmacy 5 (PDE5) which is responsible for degradation of cGMP in the corpus cavernosum.

This means that, with vardenafil on board, normal sexual stimulation leads to increased levels of cGMP in the corpus cavernosum which leads to better erections.

Without sexual stimulation and no activation of the NO/cGMP system, vardenafil should not cause an erection.

Vardenafil inhibits the cGMP specific phosphodiesterase type 5 (PDE5) which is responsible for degradation of cGMP in the corpus cavernosum located around the penis. Penile erection during sexual stimulation is caused by increased penile blood flow resulting from the relaxation of penile arteries and corpus

cavernosal

This response is mediated by the release of nitric oxide (NO) from nerve terminals and endothelial cells, which stimulates the synthesis of cGMP in smooth muscle cells. Cyclic GMP causes smooth muscle relaxation and increased blood flow into the corpus cavernosum.

The inhibition of phosphodiesterase type 5 online sildenafil usa (PDE5) by vardenafil enhances erectile function by increasing the amount of cGMP.

Vardenafil is rapidly absorbed with absolute bioavailability of approximately 15%. Vardenafil is metabolized predominantly by the hepatic enzyme CYP3A4, with contribution from the CYP3A5 and CYP2C isoforms. The major circulating metabolite, M1, results from desethylation at the piperazine moiety of vardenafil.

M1 shows a phosphodiesterase selectivity profile similar to that of vardenafil and an in vitro inhibitory potency for PDE5 28% of that of vardenafil. After oral administration, vardenafil is excreted as metabolites predominantly in the feces (approximately 91-95% of administered oral dose) and to a lesser extent in the urine (approximately 2-6% of administered oral dose). Symptoms of overdose include vision changes and back and muscle pain.
