Clinical pharmacology
Tadalafil Cialis 20mg is a reversible selective inhibitor of specific PDE-5 cGMP. When sexual arousal causes local release of nitric oxide, inhibition of PDE-5 by Cialis Tadalafil 20 Mg Tablets leads to an increase in the concentration of cGMP in the cavernous body of the penis.
