Cialis Tablets
Cialis (containing the active ingredient Tadalafil) is a highly effective prescription medication used to treat erectile dysfunction (ED) in adult men. It belongs to a class of medicines called phosphodiesterase type 5 (PDE5) inhibitors. Unlike some other ED treatments, Cialis can work for up to 36 hours, offering you and your partner more spontaneity. It is important to understand that sexual stimulation is required for Cialis to work, as it helps relax the blood vessels in the penis to allow for increased blood flow, leading to a natural-feeling erection.
