Vidalista 40 mgis a vasodilator used to treat erectile dysfunction (ED) in men. It works by relaxing the smooth muscles in the blood vessels and increasing the flow of blood to the penis. This increases blood pressure and creates an erection.

This drug is also used to treat a condition called benign prostatic hyperplasia, which is an enlarged prostate gland that causes painful and frequent urination.

The active ingredient in vidalista is tadalafil, which is a type of phosphodiesterase type 5 inhibitor. This inhibits the breakdown of cGMP, which is responsible for the contraction and dilation of blood vessels.
