Severe poisoning after self-reported use of 2-(4-iodo-2,5-dimethoxyphenyl)-N-[(2-methoxyphenyl)methyl]ethanamine, a novel substituted amphetamine: a case series
Abstract
Significant toxicity from amphetamine and cathinone derivatives is being increasingly reported. We describe a series of self-reported exposures to 2-(4-iodo-2,5-dimethoxyphenyl)-N-[(2-methoxyphenyl)methyl]ethanamine (25-I-NBOME or 25-I), a novel amphetamine derivative. Ten patients with an average age of 17 years presented to local emergency departments (EDs) in our community after ingestion and/or insufflation of a drug referred to as "25-I." Of 10 patients, 6 reported taking 25-I alone; other substances included ethanol; 2,5-dimethoxy-4-ethylphenethylamine; marijuana; and ketamine. Most common effects included tachycardia (90%), hypertension (70%), agitation (60%), and hallucinations (50%). The average heart rate was 123 beats per minute. Two patients were found in status epilepticus, and another was found unresponsive. One patient who had a seizure had multiple, discrete intraparenchymal hemorrhages and acute kidney injury. Six patients were admitted to the intensive care unit, two were treated in the ED and released, and 1 each was admitted to psychiatry or managed in a clinical decision unit and subsequently discharged. Three patients required emergent intubation, and all admitted patients (7/10) were given intravenous benzodiazepines for sedation. Urine and blood specimens were obtained from 1 patient, which showed analytic confirmation of 25-I. In addition to sympathomimetic effects, methoxy and other substituent groups impart serotonergic effects, resulting in…
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 10 participants or records.
