Vidalista 20 is a medicine that is primarily used to treat erectile dysfunction in males. Its active element is tadalafil, which helps men develop and sustain erections during sexual activity. Vidalista works by boosting blood circulation to the penis. When a man gets sexually excited, tadalafil relaxes the blood vessels in his penis, enabling more blood to enter. This promotes a hard and long-lasting erection, making sexual activity more enjoyable.
