Filitra 20 mg is a generic medication containing vardenafil, a phosphodiesterase type 5 (PDE5) inhibitor used to treat erectile dysfunction (ED) in men. It is manufactured by Fortune Healthcare and is available under various brand names, including Vilitra. Vardenafil works by inhibiting the PDE5 enzyme, leading to the relaxation of smooth muscles and increased blood flow to the penis during sexual arousal, facilitating an erection. It does not cause an erection without sexual stimulation.
