Vidalista 20 mg is a medication used primarily for the treatment of erectile dysfunction (ED) in men. It contains tadalafil as its active ingredient, which belongs to the class of drugs called phosphodiesterase type 5 (PDE5) inhibitors.

Tadalafil, the active component in Vidalista 20 mg, works by increasing blood flow to the penis during sexual stimulation. It achieves this by inhibiting the action of the enzyme PDE5, which regulates blood flow in the penile tissues. This mechanism allows for improved blood circulation in the penis, aiding in achieving and maintaining an erection sufficient for sexual activity.
