So, what is the mechanism of action of methylxanthines and how do these effects come about? (Markdown OK)

An important distinction must be made regarding **what is PDEA**; while sometimes used to refer to a law enforcement agency, in pharmacology, it almost always refers to phosphodiesterase (PDE) enzymes.
