Introduction
ACLS medications play a critical role in the management of cardiac arrest, bradycardia, and tachycardia. Knowing the correct drugs, indications, and dosages is essential for both ACLS certification exams and real-world clinical practice.
This guide provides a concise, high-yield ACLS drugs list with commonly used doses for quick reference.
Key ACLS Drugs Overview
The most commonly used ACLS medications include:
- Epinephrine
- Amiodarone
- Atropine
- Adenosine
- Dopamine
- Magnesium sulfate
Epinephrine
Indications:
- Cardiac arrest (VF, pulseless VT, PEA, asystole)
- Symptomatic bradycardia (infusion)
Dose:
- Cardiac arrest: 1 mg IV/IO every 3–5 minutes
- Infusion (bradycardia): 2–10 mcg/min
Key Point: Epinephrine is the first-line drug in cardiac arrest.
Amiodarone
Indications
- Refractory ventricular fibrillation (VF)
- Pulseless ventricular tachycardia (VT)
Dose:
- First dose: 300 mg IV bolus
- Second dose: 150 mg IV
Key Point: Used after defibrillation attempts fail.
Atropine
Indications
- Symptomatic bradycardia
Dose:
- 1 mg IV every 3–5 minutes
- Maximum: 3 mg
Key Point: First-line medication for bradycardia.
Adenosine
Indications:
- Stable narrow-complex tachycardia (SVT)
Dose:
- First dose: 6 mg rapid IV push
- Second dose: 12 mg if needed
Key Point: Administer rapidly followed by saline flush.
Dopamine
Indications:
- Symptomatic bradycardia (if atropine ineffective)
- Hypotension
Dose: 5–20 mcg/kg/min infusion
Magnesium Sulfate
Indications:
- Torsades de pointes
- Suspected hypomagnesemia
Dose: 1–2 g IV diluted in fluid
Tips to Remember ACLS Drugs
- Epinephrine is used in almost all cardiac arrest scenarios
- Amiodarone is for shock-resistant rhythms
- Atropine is for bradycardia
- Adenosine is for SVT
- Know doses and timing
Final Thoughts
Understanding ACLS medications and their dosages is essential for effective resuscitation. Regular review and practice will help reinforce these critical concepts.
