Filitra 40 mg is a medication primarily used to treat erectile dysfunction (ED) in men. It contains Vardenafil as its active ingredient, which belongs to a class of drugs called phosphodiesterase type 5 (PDE-5) inhibitors. Filitra 40 mg works by increasing blood flow to the penis during sexual stimulation, helping men achieve and maintain an erection. Vardenafil inhibits the enzyme phosphodiesterase type 5 (PDE-5), which is responsible for the breakdown of cyclic guanosine monophosphate (cGMP) in the smooth muscle cells of the penis.
