epinephrine is catecholamine acting as an agonist of adrenergic receptor {mainly alpha1 , and b1} causing positive inotropic action and peripheral vasoconstriction used in cases of anphylaxis, septic shock,refractory Vasodilatory shock {i.e. post cardiac surgery LCOS}.

nor epi. is a pre alpha adrenergic receptor agonist used in septic shock,vasodilatory shock and refractory hypotension not responding to epinephrine.

Epinephrine has a positive chronotropic affect, Cardiac output increases and positive ionotropic effect. The cummulative effect at the peripheral receptors causes an increase in systolic B.P. and decrease in diastolic B.P. Nor Epinephrine-In general when given in therapeutic doses to humans the alpha receptor is most affected. Causes intense peripheral vasoconstriction. Systolic and diastolic BP increase.
