This table summarizes the key medications used in Advanced Cardiac Life Support (ACLS), including indications, standard dosing, administration routes, and practical notes. Always consider the patientβs clinical context and consult your facilityβs protocols as needed.
Medication | Indications | Standard Dosing | Route | Notes / Clinical Tips |
---|---|---|---|---|
Epinephrine | Cardiac arrest (VF, pVT, asystole, PEA) | 1 mg every 3β5 minutes | IV/IO | Start ASAP during resuscitation; follow with flush. No max dose. |
Amiodarone | Refractory VF/pVT | 300 mg IV/IO bolus, then 150 mg if needed | IV/IO | Use after 3rd shock. Flush between meds and defibrillation. |
Lidocaine | Alternative to amiodarone in VF/pVT | 1β1.5 mg/kg, then 0.5β0.75 mg/kg q5β10min Max: 3 mg/kg |
IV/IO | Consider for torsades or amiodarone allergy; monitor for CNS effects. |
Atropine | Symptomatic bradycardia | 0.5 mg every 3β5 minutes Max: 3 mg |
IV | Ineffective in high-degree AV blocks. May worsen Mobitz II or 3Β° block. |
Adenosine | Stable narrow-complex SVT | 6 mg rapid push, then 12 mg if needed | IV (follow with flush) | Give quickly with immediate flush. Brief asystole common. Not for Afib/flutter. |
Dopamine | Bradycardia (post-atropine) or hypotension | 2β20 mcg/kg/min infusion | IV infusion | Titrate to patient response. Monitor for tachyarrhythmias. |
Magnesium Sulfate | Torsades de Pointes Hypomagnesemia |
1β2 g diluted in 10 mL D5W over 5β20 min | IV/IO | First-line for polymorphic VT with prolonged QT. Use cautiously in renal failure. |
Naloxone | Suspected opioid overdose with respiratory depression | 0.4β2 mg every 2β3 minutes Max: 10 mg |
IV/IM/SC/IN | Not part of core ACLS algorithm, but critical in opioid-associated arrest. |
Calcium Chloride | Hyperkalemia Hypocalcemia Calcium channel blocker overdose |
500β1000 mg (5β10 mL of 10% solution) | IV slow push | Use cautiously; can precipitate with bicarbonate. Avoid in routine arrest. |
Sodium Bicarbonate | Known metabolic acidosis Hyperkalemia Tricyclic overdose |
1 mEq/kg bolus | IV | Use only in specific cases. Not routine. May worsen intracellular acidosis. |
