Clinical pharmacology

Tadalafil 10mg Dosage is a reversible selective inhibitor of specific PDE-5 cGMP. When sexual arousal causes local release of nitric oxide, inhibition of PDE-5 by Tadalafil Tablets Usp 20 Mg 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 blood flow to the tissues of the penis, which causes an erection. Cialis Tadalafil Tablets has no effect in the absence of sexual arousal.

In vitro studies have shown that Tadalafil Generic Cialis 20mg is a selective PDE-5 inhibitor.

Tadalafil For Erectile Dysfunction is 10,000 times more powerful against PDE-5 than against PDE-1, PDE-2, PDE-4 and PDE-7, which are localized in the heart, brain, blood vessels, liver, leukocytes, skeletal muscles and other organs. Cialis Tadalafil 10mg Tablets is 10,000 times more active in blocking PDE-5 than PDE-3, an enzyme that is found in the heart and blood vessels. This selectivity for PDE-5 versus PDE-3 is important because PDE-3 is an enzyme involved in cardiac muscle contraction. In addition, Tadalafil Citrate Dosage is approximately 700 times more active against PDE-5 than against PDE-6, which is found in the retina and is responsible for photo transmission. Tadalafil Tablets India is also showing the action in 9000 times more potent against PDE-5 compared with its effect on PDE-8, PDE-9, PDE-10 and 14 times more potent against PDE-5 compared to PDE-11. Tissue distribution and physiological effects of PDE-8 — PDE-11 inhibition have not yet been clarified.
