epinephrine Class: Adrenergic Agonist (Nonselective)
• Action: Stimulates Alpha1 (increases BP), Beta1
(increases HR), and Beta2 (bronchodilation).
• Uses: Anaphylaxis (first line), cardiac arrest, severe
bronchospasm.
• Safety/Nursing:
◦ High Alert: IV extravasation causes tissue necrosis.
Antidote: Phentolamine mesylate.
◦ Contraindications: Narrow-angle glaucoma,
cardiac dysrhythmias (unless cardiac arrest).
• Side/Adverse Effects: Tachycardia, hypertension,
palpitations, restlessness, tremors, hyperglycemia.

albuterol Class: Beta2 Adrenergic Agonist.
• Action: Selective stimulation of Beta2 receptors in
the lungs to cause bronchodilation.
• Uses: Asthma, bronchospasm (rescue inhaler).
• Safety/Nursing:
◦ Selectivity Note: At high doses, it may lose
selectivity and stimulate Beta1 receptors in the
heart, causing tachycardia.
◦ Interaction: Beta-blockers may antagonize (block)
its effect.
• Side/Adverse Effects: Tremors, nervousness,
restlessness, tachycardia, palpitations.
atenolol Class: Beta1 Adrenergic Antagonist (Selective Beta
Blocker).
• Action: Selectively blocks Beta1 (heart) receptors.
Decreases heart rate and blood pressure.
• Uses: Hypertension, angina, acute myocardial
infarction (MI).
• Safety/Nursing:
◦ Black Box Warning: Do not stop abruptly; taper
over 1-2 weeks to prevent rebound HTN/MI.
◦ Assessment: Withhold if apical pulse is <60 or
systolic BP is <90.
◦ Respiratory: Safer than nonselective blockers for
asthma/COPD, but caution is still required.
• Side/Adverse Effects: Bradycardia, hypotension,
fatigue, dizziness, erectile dysfunction,
bronchospasm (rare with selective).
