lead to toxicity
◉ what are centrally acting alpha-2 agonists? Answer: clonidine
guanfacine
methyldopa
◉ what is the pharmacological action of centrally acting alpha-2
agonist? Answer: decreased stimulation of the adrenergic receptors
of the heart and peripheral vascular system
◉ what are beta-adrenergic blockers (sympatholytic) under
cardioselective? Answer: metoprolol

esmolol
◉ what do beta-1 meds affect?
, beta-adrenergic blockers (sympatholytic) Answer: affects the heart
only
◉ what is the purpose of beta-adrenergic blockers? Answer: block
the sympathetic activation of beta-1 receptors in the heart
heart rate and stroke volume decrease, decreasing cardiac output
and blood pressure as a result
◉ what is the MOA for beta-adrenergic blockers? Answer: blocks
beta-1 receptors in the heart
decreased rate of conduction
decreased heart rate
decreased force of contraction
◉ what are complications of beta-adrenergic blockers?
(sympatholytic) Answer: non-selective beta blockers should not be
given to our COPD and asthma patients
