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 (cGMP) in the smooth muscle cells of the corpus cavernosum.

The cGMP in turn triggers smooth muscle relaxation, allowing increased blood flow into the penis, resulting in erection.

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 buy liquid sildenafil amount of cGMP.

Learn about our commercial Contraindications & Blackbox Warnings data. Vardenafil is used to treat male erectile dysfunction (impotence) and 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 viagra 25 mg tablet buy online 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 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 smooth muscle. 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 buy liquid sildenafil flow into the corpus cavernosum. The inhibition of phosphodiesterase type 5 (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.

It comes in several different doses and is taken as-needed.

Disclaimer: The information provided on this page is not a substitute for professional medical advice, diagnosis, or treatment. If you have any questions or concerns about your health, please talk to a doctor. Levitra® functions similarly to buy liquid sildenafil Viagra®, however it comes in different doses, has an increased risk of a change seen on EKG known as QT prolongation (which can lead to irregular heartbeats, which can be dangerous), and has a decreased risk of causing the bluish visual tint that is sometimes experienced by Viagra® users. For erectile dysfunction, Levitra® should be taken without food at least 30-60 minutes before sex and its effects last up to 8 hours. Serious side effects include an erection lasting more than 4 hours, sudden vision loss in one or both eyes, and sudden hearing decrease or loss. If these occur, seek medical attention immediately.

Talk to your doctor about your medical conditions and your medications before taking Levitra®. Do not take Levitra® if you are allergic to its ingredients or if you are already taking nitrates (such as nitroglycerin), street drugs called “poppers” (such as amyl nitrate, amyl nitrite, butyl nitrate), or guanylate cyclase stimulators (such as riociguat). Levitra® is a drug that is used to treat erectile dysfunction (ED). It comes in four doses, 2.5 mg, 5 mg, 10 mg and 20 mg. The 10 mg dose is the most common starting dose, although some people may benefit from higher or lower doses. Levitra® is part of a “family” of medicines used to treat ED called phosphodiesterase-5 inhibitors (PDE5i). Other drugs in this family include Cialis (tadalafil), Viagra (sildenafil), and Stendra (avanafil). All of these drugs have the same mechanism of action, but there are subtle differences that may cause your doctor to recommend one drug out of the others based on your preferences and treatment goals. Levitra® is a short acting drug with an average half-life of 4–5 hours, which means that half the medicine is gone from the body after 4–5 hours in healthy people. The time that it takes to eliminate Levitra® may be prolonged in older people and people with liver or kidney disease meaning the drug may work longer in these people.

Levitra® functions very similarly to Viagra® with a few key differences.

Levitra® comes in doses of 2.5 mg, 5 mg, 10 mg and 20 mg, while Viagra® comes in 25 mg, 50 mg, and 100 mg doses. The most common starting dose for Viagra® is 50 mg, and the most common dose for Levitra® is 10 mg.

The use of Levitra® increases the likelihood of QT prolongation (a change seen on an EKG), which can sometimes be followed by irregular heartbeats.

In rare cases, QT prolongation can cause dangerous abnormal heart rhythms that can even be fatal.

Also, Levitra® does not cause the bluish visual tint sometimes caused by Viagra®. This is because unlike Viagra®, Levitra® does not inhibit PDE6, which is found in the retina and can cause visual color changes when blocked or inhibited. It’s also important to note that side effects are very individual, and someone who has side effects with one drug may not have them with the other.

Talk to your doctor about the risks and possible side effects before you begin taking Levitra or Viagra. Some people think that higher is always better when it comes to ED medication and may even take more than the highest FDA-approved dose of Levitra®, which is 20 mg. Levitra® has been studied in doses higher than 20 mg, including 40 mg twice daily. The reason the maximum FDA-approved dose of Levitra® is 20 mg is because above that dosage there is very little increase in benefit with a much higher risk of side effects. Even within the FDA-approved doses, there is

The most important things to do to maximize effectiveness of Levitra® is to take it properly, as prescribed.

This means it sildenafil no rx should not be taken with a high fat meal.

Taking Levitra® with a high fat meal delays absorption by about 1 hour and also decreases the maximum blood level.

This effect of delayed absorption was not shown with a meal that was lower in fat. It’s also important to take Levitra® at the correct time. It should be taken 30–60 minutes before sexual

activity

It is also recommended to not mix Levitra® with alcohol.

Levitra® should not be taken more than once every 24 hours, and you should never mix Levitra® with other ED medications.

Taking Levitra® with a high fat meal delays absorption by about 1 hour and also decreases the maximum blood level. It should be taken 30–60 minutes before sexual activity. The effects of Levitra typically last for a maximum of about 8 hours, although its strongest effects are within the first 4 hours.

It is also recommended to not mix Levitra® with alcohol.

The most common side effects of Levitra® include headaches, facial flushing, stuffy nose, and upset stomach.

Serious side effects that are rare include an erection that will not resolve even after 3–4 hours (priapism), hearing loss, which can be sudden, and vision loss in one or both eyes.

For more information about side effects, see Levitra® side effects below. What Should You Know Before Taking Levitra® Who should not take Levitra®?

Keep a list of them to show to your healthcare provider and pharmacist when you get a new medicine. Rarely reported side effects include: an erection that will not go away (priapism) .

If you have an erection that lasts more than 4 hours, get medical help right away.

If it is not treated right away, priapism can permanently damage your penis.

Sudden vision loss in one or both eyes can be a sign of a serious eye problem called non-arteritic anterior ischemic optic neuropathy (NAION).

It is uncertain whether PDE5 inhibitors directly cause the vision loss.

Stop taking Cialis® and call your healthcare provider right away if you have sudden vision loss in one or both eyes. Some people may also have ringing in their ears (tinnitus) or dizziness.

If you have these symptoms, stop takingCialis® or generic Cialis® and contact a doctor right away.
