Take Vidalista 20 half an hour before sexual activities to make sure you get the most out of it. As the tissue relaxes, it allows enough blood to enter the penis during sexual action. This medication allows you to stay alert without suffering negative consequences. Vidalista 20mg works by dilating blood vessels, almost like the erectile dysfunction drug Sildenafil does. A specific PDE-5 inhibitor is the main component. This medication allows cGMP to build up in the genital area, which improves blood flow. Vidalista 20 can be described as a prescription medication used to treat a variety of blood circulation problems, including erectile dysfunction, hypertension, and hyperplasia.
