Filitra 40 mg is marketed as a medicine containing vardenafil, a phosphodiesterase type 5 (PDE5) inhibitor used to treat erectile dysfunction (ED) in adult men. Vardenafil works by increasing blood flow to the penis during sexual stimulation, helping men achieve and maintain an erection. It does not directly increase sexual desire, and sexual stimulation is required for it to work. A key consideration with Filitra 40 mg is its strength. Official prescribing information for vardenafil recommends a starting dose of 10 mg, which may be reduced to 5 mg or increased to a maximum recommended dose of 20 mg once daily, depending on effectiveness and side effects.
