http://en.wikipedia.org/wiki/Epinephrine
Epinephrine (also known as adrenaline, adrenalin, or 4,5-β-trihydroxy-N-methylphenethylamine) is a hormoneand a neurotransmitter.The investigation of the pharmacology of epinephrine made a major contribution to the understanding of the autonomic system and the function of the sympathetic system. Epinephrine remains a useful medicine for several emergency indications. This is despite its non-specific action on adrenoceptors and the subsequent development of multiple selective medicines that target subtypes of the adrenoceptors. The word adrenaline is used in common parlance to denote increased activation of the sympathetic system associated with the energy and excitement of the fight-or-flight response. The influence of adrenaline is mainly limited to a metaboliceffect and bronchodilation effect on organs devoid of direct sympathetic innervation.
