Vidalista 80 is a medication that contains tadalafil as its active ingredient. Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor, and it is primarily used for the treatment of erectile dysfunction (ED) in men. It is typically recommended to take Vidalista 80 about 30 minutes before anticipated sexual activity. The medication's effects may last for up to 36 hours, providing a longer window of opportunity compared to some other ED medications.
