FDA approved tadalafil in 2003 for erectile dysfunction. The same drug is used for treating benign prostatic hyperplasia where the prostrate gland becomes enlarged and pulmonary arterial hypertension where the arteries carrying blood from the heart to lungs have high blood pressure.

How does Cialis work?

When the penis gets filled with blood, a penile erection happens. The blood vessels that take blood to the penis gets dilated which in turn increases the supply of the blood and the blood vessels which removes blood from the penis contracts. Therefore, the blood gets trapped in the penis, and the erection happens.

Nitric oxide gets released into the penis as a man is sexually stimulated, which is responsible for the production of cGMP. cGMP is an enzyme responsible for dilation and contraction of blood vessels of the nerves which carries blood to and from the penis. Now, PDE5 is a substance which kills cGMP and brings back the blood vessels to their normal form, and so the erection stops. When tadalafil is consumed, it destroys cGMP, and this is the reason the erection lasts longer.

The same thing happens in the lungs too. The walls of lungs have arteries, and the muscles of the arteries contain PDE5, that is how the same drug can help for the treatment of pulmonary artery hypertension.
