Vidalista Black 80 mg is a potent medication used to treat erectile dysfunction (ED) in men. It contains Tadalafil as its active ingredient, which is a well-known PDE5 inhibitor. This class of drugs works by relaxing the blood vessels in the penis, improving blood flow during sexual arousal, and helping men achieve and maintain an erection. Tadalafil (the active ingredient) inhibits the enzyme PDE5. By doing so, it allows cyclic GMP to accumulate, which in turn promotes the relaxation of smooth muscle and improved blood flow to the penis. This process helps with achieving an erection when sexually stimulated.
