What is Cialis?

Cialis is the brand name for the drug tadalafil, prescribed primarily for the treatment of erectile dysfunction (ED) and benign prostatic hyperplasia (BPH). Approved by the FDA in 2003, Cialis has become a first-line therapy for millions of men globally, prized for its long-lasting effects and gentle onset. Unlike its well-known competitor Viagra (sildenafil), Cialis is commonly referred to as “the weekend pill,” thanks to its extended window of effectiveness.

Active Ingredient: Tadalafil
Class: Phosphodiesterase type 5 (PDE5) inhibitor
Uses: Treatment of erectile dysfunction, BPH, and sometimes pulmonary arterial hypertension
Onset of Action: 30-60 minutes

How Does Cialis Work? Understanding the Mechanism of Tadalafil

Cialis belongs to a class of medications called PDE5 inhibitors. These drugs increase blood flow to the penis during sexual stimulation by blocking the PDE5 enzyme, which otherwise constricts blood vessels. The result? Improved ability to achieve and maintain a firm erection.

Infographic: Cialis’ Pathway to Effectiveness

Step	Description
1. Sexual stimulation occurs	The brain signals the release of nitric oxide in the penis
2. Nitric oxide increases cGMP	cGMP relaxes smooth muscles and dilates blood vessels
3. PDE5 inhibition by Cialis	Cialis blocks PDE5, allowing cGMP to remain active longer
4. Increased blood flow	Enhanced blood flow results in a strong, lasting erection
