This product is a selective reversible inhibitor of cGMP specific phosphodiesterase 5 (PDE5). When sexual stimulation leads to the local release of nitric oxide, PDE5 is inhibited by Tadalafil, leading to an increase in cGMP levels in the cavernous penile, which results in the relaxation of smooth muscle, blood flow to the penile tissues, and erection.
