Sympathomimetics Flashcards
albuterol
beta 2 agonist
treats bronchial asthma
salmeterol
beta 2 agonist
treats nighttime asthma
prophylaxis of asthma as inhaler
formoterol
beta 2 agonist
treats nighttime asthma
prophylaxis of asthma as inhaler
metaproterenol
beta 2 agonist
relaxes bronchial smooth mm
treats bronchial asthma
terbutaline
beta 2 agonist
NOT metabolized by COMT
treats bronchial asthma
delayed delivery
ritodrine
beta 2 agonist
used to delay delivery
Epinephrine
andrenergic agonist bronchial relaxation urine retention spleen contraction pupil dilation uterus relaxation blocks release of insulin
treats: asthma, anaphylactic shock, glaucoma
adverse affects: arrhythmia, fear, anxiety, HA
NE
alpha 1/2 and beta 1 agonist
increase BP –> reflex bradycardia
used to manage hypotension during anesthesia
isoproterenol
beta 1/2/3 agonist increased HR and force of contraction vasodilation no change in BP relaxes bronchial/uterine smooth mm
treats: asthma, heart block, cardiogenic shock after MI (b/c increases CO and BF)
dopamine
D1 and beta 1 agonist
vasodilation of mesenteric and renal vascular beds
treats: chronic CHF (increases CO w/o increasing TPR)
dobutamine
beta 1 agonist
increases CO in pts w/ cardiogenic shock w/ decreased risk of arrhythmia than dopamine
phenylephrine
alpha 1 agonist
vasoconstriction –> reflex bradycardia
used for: nasal decongestant, glaucoma, mydriasis
methoxamine
alpha 1 agonist
vasoconstriction –> reflex bradycardia
used for: nasal decongestant, glaucoma, mydriasis
