When sexual arousal causes local release of nitric oxide, inhibition of PDE5 by Tadalafil Usa 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. Tadalafil 5mg India has no effect in the absence of sexual arousal.
In vitro studies have shown that Cialis Tadalafil Tablets is a selective PDE5 inhibitor.

In patients with severe renal failure (Creatinine CL <30 ml/min and hemodialysis): use of Tadalafil 10mg Dosage is contraindicated.
Side effect
Most often: headache, dyspepsia. Possible: back pain, myalgia, nasal congestion, blood flow to the face. Rarely: swelling of the eyelids, pain in the eyes, conjunctival hyperemia, dizziness.

Interaction with other drugs
Tadalafil For Erectile Dysfunction is mainly metabolized by the enzyme CYP3A4. Selective inhibitor CYP3A4 ketoconazole increases AUC by 107%, and rifampicin reduces it by 88%.
