Vidalista Black 80 mg is a phosphodiesterase type 5 inhibitor of the class. It is used to treat male impotence that occurs during sexual activity, also known as erectile dysfunction. It functions as an inhibitor of phosphodiesterase type 5 by blocking its activity, which raises cGMP levels and lowers penile blood pressure. Take the medication with or without food, and with a glass of water. Still, better results come from going into it empty-handed. Give yourself 30 to 60 minutes before you do anything romantic. Never take medication without a prescription from a physician. If you experience any allergic reactions while taking it, stop taking it. As soon as you can, see your doctor. Make sure it's out of reach of the kids.
