Filitra Professional contains vardenafil as its active component. Vardenafil belongs to the phosphodiesterase-5 (PDE-5) inhibitor class and is used to treat erectile dysfunction (ED). The medication is supplied as a 20 mg pill and is available by prescription in Hong Kong under the oversight of the Department of Health.
Vardenafil blocks the enzyme phosphodiesterase-5, which normally breaks down cyclic guanosine monophosphate (cGMP) in the penile tissue. By inhibiting PDE-5, cGMP levels remain elevated after sexual stimulation, leading to smooth-muscle relaxation and increased blood flow into the corpus cavernosum. This physiological response enables an erection to develop and be maintained.
Vardenafil is rapidly absorbed from the gastrointestinal tract, with an oral bioavailability of roughly 15 %. It is metabolized primarily by the liver enzyme CYP3A4 and excreted in the urine and feces.
Filitra Professional is approved in Hong Kong for the treatment of erectile dysfunction in adult men. The medication is indicated for individuals who have difficulty achieving or maintaining an erection sufficient for satisfactory sexual performance.
These effects are usually mild, resolve without treatment, and may diminish with continued use.
Patients should disclose all medications, supplements, and herbal products to their healthcare provider before starting Filitra Professional.

Moderate alcohol consumption does not typically reduce the effectiveness of vardenafil, but excessive drinking can increase dizziness and lower blood pressure, potentially worsening side effects. It is advisable to limit alcohol intake when planning sexual activity.
On average, the medication begins to work within 30-60 minutes after ingestion. Food, especially a high-fat meal, may delay the onset by up to an hour.
Men with diabetes often experience erectile dysfunction and may benefit from vardenafil. However, they should have their cardiovascular status evaluated and ensure blood glucose is well controlled before use.
A prolonged erection (priapism) is a medical emergency. Seek immediate medical attention; prompt treatment can prevent permanent tissue damage.
Vardenafil can be combined with alpha-blockers, but dose timing and monitoring are important to avoid sudden blood-pressure drops. Discuss a safe regimen with your physician.
There are no strict dietary restrictions, but avoid large amounts of grapefruit juice, as it can increase vardenafil blood levels and raise the risk of side effects.
Older men can use the medication, but they should start at the lowest effective dose and be monitored for hypotension and other age-related sensitivities.
Keep the medication in its original container, stored at room temperature, and protected from moisture. Carry it in your hand luggage to avoid temperature extremes in checked baggage.
Certain supplements, such as L-arginine or yohimbine, can affect blood pressure or vascular tone and may interact with vardenafil. Always inform your healthcare provider about any supplements you take.
While all three are PDE-5 inhibitors, vardenafil (Filitra Professional) typically has a slightly faster onset and a shorter duration of action compared with sildenafil. Individual response varies, and the choice should be based on physician guidance and personal tolerability.
