Question: What is the most common drugs you use on blood vessels?

Majid Ahmed answered on 17 Mar 2016:

The most common drug I use is called acetylcholine. It is a chemical that occurs naturally in the body and is released from nerve cells called neurons to stimulate various actions. In the blood vessels, adding acetylcholine tells the muscle within the vessel to relax, which opens the blood vessel and allows more blood to flow through.
