Cialis contains tadalafil, which belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors. It improves the blood flow to the penis helping achieve and maintain erection in men suffering with Erectile dysfunction (ED). It can also be used in treating symptoms of prostate enlargement and sometimes in the treatment of pulmonary hypertension. It is most well-known for its longer lasting therapeutic effect.

Cialis could help achieve an erection anytime between 30 minutes to 36 hours of taking it, hence it is also referred to as the ‘’weekend pill’’.
