What Is Cialis? Answers from the Experts

Cialis (generic name: tadalafil) belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. FDA-approved and globally recognized, it helps men achieve and maintain firm, lasting erections when they’re sexually stimulated. Unlike other ED medicines, Cialis has a longer duration of action—up to 36 hours—which is why it’s often called “the weekend pill.”

Active Ingredient: Tadalafil
Approved Uses: Erectile Dysfunction, Benign Prostatic Hyperplasia (BPH)^[1]
Available Dosages: 2.5 mg, 5 mg, 10 mg, 20 mg tablets

How Does Cialis Work? The Science, Simplified

During sexual arousal, nitric oxide is released in the penis, which activates enzymes and increases blood flow. Cialis (tadalafil) specifically inhibits the PDE5 enzyme, preventing the breakdown of cGMP—a molecule essential for the relaxation of smooth muscle and increased blood flow in the penis. The result: improved ability to achieve and sustain an erection in response to sexual stimulation.
