Cialis 20 mg is an oral prescription medication containing the active ingredient tadalafil. It belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. It is primarily prescribed for the treatment of erectile dysfunction (ED) in adult men. By helping to relax the blood vessels in the penis, it increases blood flow to facilitate achieving and maintaining an erection when accompanied by sexual stimulation. The effects of Cialis can last for up to 36 hours, which is why it is sometimes referred to as the weekend pill.
