How does Tadapox work? 

Tadapox aids in achieving and maintaining an erection by boosting blood flow to the penis. It accomplishes this by blocking the breakdown of the chemical messenger cyclic guanosine monophosphate (cGMP) by the enzyme phosphodiesterase type 5 (PDE5). By relaxing blood vessels and increasing blood flow to the penis, PDE5 inhibition increases cGMP levels.

Who isn't meant to utilize Tadapox ? 

People who have an allergy to any of the substances in the drug, including tadalafil, should not take it. Additionally, because it might result in a potentially abrupt reduction in blood pressure, it should not be taken by anyone taking nitrate medicine for cardiac issues or chest pain.
