Medication for the treatment of erectile dysfunction. Excellent for PCT. Tadalafil is a reversible selective inhibitor of specific phosphodiesterase type 5 (PDE-5) cyclic guanosine monophosphate (cGMP). When sexual arousal causes local release of nitric oxide, inhibition of PDE-5 by tadalafil leads to an increase in the concentration of cGMP in the cavernous body of the penis. The consequence of this is the relaxation of the smooth muscles of the arteries and the flow of blood to the tissues of the penis, which causes an erection.
