Vilitra works by blocking the enzyme phosphodiesterase type 5 (PDE5), which can restrict blood flow to the penis. By inhibiting PDE5,
Vilitra allows cyclic GMP (cGMP) to build up, leading to the relaxation of the smooth muscles in the blood vessels of the penis, thereby increasing blood flow. This enhanced blood flow helps men with ED to achieve an erection when sexually stimulated. However, Vilitra does not cause an erection automatically; sexual arousal is still required for it to work effectively. By increasing blood flow to the penis, it helps men with ED achieve and maintain an erection, improving sexual performance and satisfaction. However, it is essential to use Vilitra under the guidance of a healthcare provider, especially to avoid potential interactions with other medications or underlying health conditions.
