Vidalista 10 mg is Tadalafil, a PDE5 inhibitor. It works by blocking the enzyme PDE5 in the body, which leads to increased blood flow to the penis during sexual stimulation. This helps a man achieve and maintain an erection. Tadalafil works by relaxing the smooth muscles in the blood vessels of the penis, which allows for increased blood flow. It does not automatically cause an erection — sexual arousal is still needed to trigger the effect.
