The medication was first developed in England for used as an blood pressure reducer, but it worked better for penile dysfunction, so the makers decided to market it for that. In the year 2000, Viagra (sildenafil) reportedly accounted for 92% of the global market for prescribed erectile dysfunction pills. It is still known all over the globe and some herbal supplements even market themselves as the "herbal Viagra."

These studies have shown that tadalafil is >10,000-fold more potent for PDE5 than for PDE1, PDE2, PDE4, and PDE7 enzymes, which are found in the heart, brain, blood vessels, liver, leukocytes, skeletal muscle, and other organs. Tadalafil is >10,000-fold more potent for PDE5 than for PDE3, an enzyme found in the heart and blood vessels. Additionally, tadalafil is 700-fold more potent for PDE5 than for PDE6, which is found in the retina and is responsible for phototransduction. Tadalafil is >9,000-fold more potent for PDE5 than for PDE8, PDE9, and PDE10. Tadalafil is 14-fold more potent for PDE5 than for PDE11A1 and 40-fold more potent for PDE5 than for PDE11A4, two of the four known forms of PDE11. PDE11 is an enzyme found in human prostate, testes, skeletal muscle and in other tissues (e.g., adrenal cortex).

The physiological role and clinical consequence of PDE11 inhibition in humans have not been defined.
