Cialis 20mg is a presscea prescription medication primarily utilized for the on-demand treatment of erectile dysfunction (ED) in adult men.
It features the active ingredient tadalafil and represents the maximum standard dosage prescribed for use on an “as-needed” basis.
Active Ingredient & Mechanism
The active compound in Cialis is tadalafil, which belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors.
How it works: Tadalafil relaxes the smooth muscles and blood vessels supplying the penis, significantly increasing local blood flow.
Requirement for efficacy: The medication does not automatically trigger an erection on its own; natural sexual stimulation is completely necessary to initiate the physiological response.
