What is the mechanism of action of Cialis 20 mg?

[hazelwilliams]

Cialis 20 mg [https://medzpills.com/product/tadalafil ... lis-20-mg/], containing the active ingredient tadalafil, operates by inhibiting the enzyme phosphodiesterase type 5 (PDE5) within the body. PDE5 is responsible for the degradation of cGMP, a chemical messenger that helps relax smooth muscle tissues in the arteries of the penis, leading to increased blood flow during sexual stimulation and thus facilitating erection. By blocking PDE5, Cialis 20 mg prolongs the presence of cGMP, allowing for sustained vasodilation and improved erectile function. It's important to note that sexual stimulation is still required for the medication to produce its effect, as Cialis 20 mg alone does not cause spontaneous erections.
