define catecholamines. what response can it produce?
they are chemical structure of a substance that can produce a sympathomimetic response
sympathomimethic: adrenergic agonist
acts on alpha1, beta1 and 2 receptors causing vasoconstriction
what is epinephrine used for

drugs that block the effects of adrenergic neurotransmitters are______. what do they block?
adrenergic antagonist or adrenergic blockers. they either block alpha or beta receptors
your patient is experiencing tachycardia, HTN, urinary retention, etc. what type of drug will you give?
an adrenergic antagonist
effects of adrenergic blockers on receptors
