What Is Levitra

Levitra tablets, containing Vardenafil are available in various strengths, with most commonly prescribed dosage Levitra 20mg within the Australian pharmaceutical market.

How Does Levitra Work

During sexual arousal, the brain sends signals that trigger the release of nitric oxide in the erectile tissue of the penis. Nitric oxide activates an guanylate cyclase, which increases levels of cyclic guanosine monophosphate (cGMP). Elevated cGMP levels promote relaxation of the smooth muscle in the corpus cavernosum, allowing increased blood flow into the penis. Levitra specifically targets phosphodiesterase type 5 (PDE5), an enzyme that breaks down cGMP. By inhibiting PDE5, vardenafil helps maintain higher cGMP levels, prolonging smooth muscle relaxation and sustaining increased blood flow.

Research published in the Australian Journal of Urology (2019) demonstrated that vardenafil has a particular molecular structure that allows for high selectivity for PDE5 compared to other phosphodiesterase enzymes. The study showed that vardenafil's binding affinity to PDE5 is approximately 10 times greater than sildenafil, potentially allowing for effective treatment at lower doses in some patients.

Levitra Dosage

Levitra dosage start with a 10mg dose taken approximately 60 minutes before sexual activity, but can then be adjusted up to levitra 20mg or down to 5mg. Maximum recommended frequency - once per 24 hours. For men over 65 years of age, the recommended starting dose is lower at 5mg, as older patients typically metabolize the medication more slowly.

The maximum daily dose should not exceed 20mg in 24 hours. Vardenafil is generally not recommended for daily administration. The as-needed dosing regimen aligns with its pharmacokinetic profile and 4-6 hour window of effectiveness. If a dose is "missed," there's no need for concern as vardenafil is taken as needed rather than on a fixed schedule.

Levitra Effect Duration

Most men notice initial effects beginning within 25-60 minutes after taking vardenafil. This onset time can vary based on whether the medication was taken with food and other physiological factors. For optimal results take levitra tablets approximately 60 minutes before sexual activity. The peak concentration of vardenafil in the bloodstream typically occurs between 30-120 minutes after ingestion.The effective duration of vardenafil ranges from 4-6 hours for most men.

In levitra vs viagra comparisons of duration, vardenafil's window of effectiveness is similar to sildenafil, typically offering a 4-6 hour period of enhanced erectile function. This contrasts with tadalafil, which can remain effective for up to 36 hours.

How To Use Levitra

Levitra should be taken 60 minutes before anticipated sexual activity, though many men report effects beginning as early as 25 minutes after ingestion. The tablet should be swallowed whole with water, without crushing or breaking it. Heavy or high-fat meal may delay the onset of action by 60 minutes or more. Take the medication on an empty stomach or after a light meal. Grapefruit and grapefruit juice should be avoided as they can inhibit the enzymes that metabolize vardenafil, potentially leading to higher blood levels and increased risk of side effects.

Levitra and Alcohol

Vardenafil and alcohol is generally not recommended to combine due to potential additive effects on blood pressure. Both substances can cause widening of blood vessels, and when used together, they may cause excessive drops in blood pressure leading to dizziness, lightheadedness, fainting, headaches, and increased heart rate.

Australian medical guidelines suggest that if alcohol consumption occurs while using vardenafil, it should be accompanied by adequate hydration and awareness of symptoms like dizziness or rapid heartbeat.
