Men with erectile dysfunction, often known as sexual impotence, are treated with Vidalista 60 mg . Tadalafil is a member of the class of drugs known as phosphodiesterase 5 (PDE5) inhibitors. These drugs limit the overactive activity of an enzyme called phosphodiesterase type-5. This enzyme functions, among other places.

The penis does not harden and expand when a man is sexually excited or when he is unable to maintain an erection, which is a condition known as erectile dysfunction. An erection is the natural result of a man's body responding to sexual stimulation by increasing blood flow to his penis. Tadalafil helps to sustain an erection after the penis has been stroked by boosting blood flow to the penis by regulating the enzyme. Tadalafil will not operate to generate an erection if the penis is not physically moved, as occurs during sexual activity.
