Vilitra 20 mg is a prescription medication containing vardenafil, a phosphodiesterase type 5 (PDE5) inhibitor, used to treat erectile dysfunction (ED) in men. It is a higher-dose option compared to Vilitra 10 mg and is intended for men who may not achieve satisfactory results with lower doses. During sexual arousal, nitric oxide (NO) is released in the penile tissue, increasing cyclic GMP (cGMP) levels. cGMP relaxes smooth muscles in the penile blood vessels, allowing increased blood flow into the penis, resulting in an erection.
