Filitra 40 mg contains Vardenafil, which is a medication primarily used to treat erectile dysfunction (ED) in men. Vardenafil is a phosphodiesterase type 5 (PDE5) inhibitor, similar to Sildenafil and Tadalafil, which works by increasing blood flow to the penis during sexual stimulation, thereby facilitating erections. Filitra 40 mg contains 40 mg of Vardenafil, which is a relatively high dose compared to other ED medications. Higher doses may be prescribed for individuals who do not respond adequately to lower doses or who have more severe ED. Vardenafil, the active ingredient in Filitra 40 mg, is generally effective in improving erectile function and helping men achieve and maintain erections sufficient for satisfactory sexual activity. However, individual response to the medication can vary, so it's essential to follow your healthcare provider's recommendations regarding dosage and use.
