Extracorporeal therapy for amlodipine poisoning

Area of Science:

• Cardiology
• Toxicology
• Critical Care Medicine

Background:

• Amlodipine overdose can cause refractory shock, unresponsive to standard treatments.
• Extracorporeal therapies like ECMO and TPE are known but rarely used together for drug poisoning.

Observation:

• A young male presented with severe amlodipine poisoning and refractory shock.
• Conventional treatments including vasopressors, insulin, calcium gluconate, and glucagon were ineffective.

Findings:

• Venoarterial ECMO was initiated for hemodynamic support.
• Total Plasma Exchange (TPE) was performed to remove protein-bound amlodipine.
• The combination of ECMO and TPE proved effective in stabilizing the patient.

Implications:

• This case demonstrates the feasibility of using ECMO and TPE as a combined strategy for severe amlodipine poisoning.
• This approach offers a potential lifesaving option for critically ill patients with drug overdose.
• Further research into extracorporeal therapies for toxicological emergencies is warranted.
