NUR 339 Final Drugs1. Epinephrine (Adrenaline)
Epi-Pen
Answer
Adrenergic drug - SNS stimulation
Treats
anaphylaxis, shock and cardiac arrest, bronchoconstriction. Action
Increases CO, blood flow, BP, causes bronchodilation.
AEs
dysrhythmias, HTN, excess CNS stimulation.
2. Norepinephrine (Levophed) IV drip
Answer
Adrenergic drug - SNS stimulation Action
stimulates alpha receptors only--vasoconstriction
Use
severe hypotension, stimulates vasoconstriction -> increasing BP AEs" severe decrease in blood
flow to periphery (decreases it further) NIs
assess cap refill, pulses, and temp.
3. Dopamine (Intropin)
Answer
Adrenergic drug - SNS stim. Variable effects
Low
increase renal blood
Med
,increase HR and CO (positive inotropic) High
alpha-vasoconstriction and increase BP.
AEs
dysrhythmia, tachycardia, decreased blood flow to periphery. IV infiltration -> tissue necrosis
with extravasation -> Regitine (phentolamine) ANTIDOTE
4. Prazosin (Minipress)
Answer
Anti-adrenergic - SNS inhibitor. ALPHA Adrenergic antag- onist
Use
treats hypertension
Action
occupy the alpha-receptor sites on smooth muscle of blood vessels -> vasodilation, decrease
peripheral vascular resistance, decrease BP
AEs
1st dose effect
decreases BP & syncope due to orthostatis hypotension. NIs
Give bedtime, monitor BP and flushing.
5. Propranolol (Inderal)
Answer
Anti-adrenergic - SNS inhibitor.BETA adrenergic antago- nists (blockers)
Use
hypertension, HF, some dysrhythmias, migraine, angina, and glaucoma. Actions
, decrease BP and force of contractions, decrease HR
AEs
hypotension, blurred vision, bradycardia, mental depression.
Avoid with asthma (causes bronchospasms) Teach to take pulse once a week.
6. Bethanecol (Urecholine)
Answer
Cholinergic drug - PNS stimulation Direct-acting- stimulates the cholinergic receptors
Use
treats urinary retention and paralytic ileus
AEs
n/v/d, bronchoconstriction, increase resp and oral secretions, bradycardia, decrease LOC ->
coma, pupil constriction (miosis)
7. Neostigmine (Prostigmin) OR
Pyridostigmine
Answer
Cholinergic - PNS stimulation Indirect-acting -- blocks acetylcholinesterase
Use
treats MG, reverse neuromuscular blockers, treat Alzheimer's Antidote for cholinergic OD? -->
ATROPINE
8. Atropine
Answer
Anticholinergic - PNS inhibitor
Increases HR in symptomatic bradycardia and heartblock. Treats bradycardia and
bronchoconstriction
