Electrocardiographic Abnormalities, Malignant Ventricular Arrhythmias, and Cardiomyopathy Associated With Loperamide Abuse.
A 20-year-old man presented with recurrent syncope and abnormal electrocardiogram (ECG). His evaluation revealed a prolonged QT interval >600 milliseconds, witnessed torsades de pointes (TdP), and dilated cardiomyopathy. At his initial admission, an ICD was implanted and atrial pacing at 80 beats per minute suppressed ventricular arrhythmias. The patient was readmitted with device infection and...
متن کاملERRATUM: Unexpected Serious Cardiac Arrhythmias in the Setting of Loperamide Abuse.
Loperamide (Imodium) is a non-prescription opioid receptor agonist available over-the-counter for the treatment of diarrhea. When ingested in excessive doses, loperamide can penetrate the blood-brain barrier and is reported to produce euphoria, central nervous system and respiratory depression, and cardiotoxicity. There is an emerging trend in its use among drug abusers for its euphoric effects...
متن کاملVentricular Tachycardia Triggered by Loperamide and Famotidine Abuse
A 32-year-old male developed recurrent ventricular tachycardia after taking mega doses of loperamide and famotidine in order to experience an opiate-like euphoric effect. He was taking up to 200 mg of loperamide and multiple doses of famotidine each day. He developed palpitations and syncope. Electrocardiography demonstrated ventricular tachycardia and QT interval prolongation (corrected QT int...
متن کاملVentricular fibrillation due to overdose of loperamide, the “poor man’s methadone”
Loperamide is an over-the-counter antidiarrheal agent that is considered by many patients to be safe, but has been used as a drug of abuse due to its opioid properties. However, cardiotoxicity has been reported, prompting the FDA to release a warning regarding the arrhythmogenic potential of loperamide. We present a case of a 38-year-old female presenting with cardiac arrest thought to be secon...
متن کاملLoperamide Induced Life Threatening Ventricular Arrhythmia
Loperamide is over-the-counter antidiarrheal agent acting on peripherally located μ opioid receptors. It is gaining popularity among drug abusers as opioid substitute. We report a case of a 46-year-old male that was presented after cardiac arrest. After ruling out ischemia, cardiomyopathy, pulmonary embolism, central nervous system pathology, sepsis, and other drug toxicity, we found out that p...
