Cialis is an oral medication containing tadalafil, used primarily to treat erectile dysfunction in adult men. Unlike many other treatments, Cialis is known for its long-lasting effect, earning the nickname “the weekend pill” due to its ability to remain effective for up to thirty-six hours. It is also prescribed for benign prostatic hyperplasia and in some cases for pulmonary arterial hypertension. Cialis helps men regain confidence in their sexual health by supporting natural erectile function.

Mechanism of Action
Tadalafil, the active ingredient in Cialis, works by increasing blood flow to the penis during sexual stimulation. Normally, when a man is aroused, the body releases nitric oxide, which promotes the production of a molecule called cyclic guanosine monophosphate. This molecule helps relax the muscles in the walls of the blood vessels in the penis, allowing for increased blood flow and resulting in an erection.

Cialis works by inhibiting the enzyme phosphodiesterase type five, which breaks down cyclic guanosine monophosphate. By blocking this enzyme, Cialis allows the natural process of erection to last longer and function more effectively. Its longer half-life means it stays in the system longer than similar medications, allowing for more spontaneous and natural intimacy.
