Tadalafil, the active ingredient in Vidalista Black 80 mg, works by inhibiting the PDE5 enzyme (phosphodiesterase type 5). This enzyme typically breaks down cGMP, a substance that helps relax the smooth muscles of the penis, allowing blood vessels to expand and increasing blood flow. By inhibiting PDE5, Tadalafil helps to maintain higher levels of cGMP, resulting in improved blood flow to the penis, which facilitates an erection when sexually aroused. The effects of Vidalista Black 80 mg can last up to 36 hours, which means you can engage in sexual activity during that period without having to take additional doses.
