Vidalista 60 mg is a medication used to treat erectile dysfunction (ED) in men. It contains tadalafil as its active ingredient, which is a phosphodiesterase type 5 (PDE5) inhibitor. Like other PDE5 inhibitors, tadalafil works by increasing blood flow to the penis during sexual stimulation, allowing a man to achieve and maintain an erection. Tadalafil, the active ingredient in Vidalista, is known for its longer duration of action compared to some other ED medications. It can remain effective for up to 36 hours.
