Filitra 10 mg is marketed as a product containing vardenafil, a phosphodiesterase type-5 (PDE5) inhibitor used to treat erectile dysfunction (ED) in adult men. Vardenafil helps improve blood flow to the penis during physical stimulation, supporting the ability to achieve and maintain an erection. Vardenafil works by inhibiting the PDE5 enzyme. During physical arousal, the body releases nitric oxide, which increases levels of cGMP. This chemical helps relax the smooth muscles and blood vessels in the penis.
