Vidalista 20 mg is a medication used to treat erectile dysfunction (ED) in men. It contains Tadalafil, a PDE5 inhibitor, which works by increasing blood flow to the penis, allowing men with ED to achieve and maintain an erection during sexual activity.

Tadalafil is a well-known PDE5 inhibitor, the same active ingredient found in Cialis. It is designed to improve erectile function by promoting better blood flow to the penis when sexually stimulated.

Tadalafil works by blocking the phosphodiesterase type 5 (PDE5) enzyme, which increases the levels of cyclic GMP (cGMP) in the penis. This results in the relaxation of smooth muscle and dilation of blood vessels, allowing for improved blood flow to the penis, which is essential for an erection.

Vidalista tablet generally starts working within 30 to 60 minutes after ingestion.

The effects can last up to 36 hours, which is why Tadalafil is often referred to as the "weekend pill." This allows for spontaneous sexual activity within a long window of time.
