Vidalista tablets is primarily used to treat erectile dysfunction (ED) in men. The active ingredient in Vidalista is Tadalafil, a PDE5 inhibitor that helps increase blood flow to the penis, which makes it easier to achieve and maintain an erection when sexually aroused. Tadalafil helps relax the blood vessels in the lungs, improving blood flow and reducing the workload on the heart. This is an off-label use and not the primary indication for Vidalista, but it is related to the medication's ability to relax blood vessels. Vidalista is known for its long-lasting effects, which can remain active for up to 36 hours.
