Seizures, Systemic Inflammatory Response, and Rhabdomyolysis Associated With Laboratory-Confirmed 2C-I and 25-I Exposure.

Pediatric Emergency Care October 1, 2018 Stephen L Thornton, Sarah Hoehn, Roy R Gerona 6 citations

The 2C drugs are hallucinogenic phenethylamines. They and their n-benzyloxymethyl analogs have become popular as "legal highs," and significant toxicity has been attributed to their use. We report on a case of seizures, systemic inflammatory response, and rhabdomyolysis associated with laboratory-confirmed 4-iodo-2,5-dimethoxyphenethylamine and 4-iodo-2,5-dimethoxy-N-(2-methoxybenzyl)...

Beyond Ketamine and Phencyclidine: Analytically Confirmed Use of Multiple Novel Arylcyclohexylamines.

Journal of Psychoactive Drugs 2017 Stephen L Thornton, David Lisbon, Thomas Lin et al.

Methoxetamine and 3-methoxy-phencyclidine are novel arylcyclohexylamines whose use and clinical toxicity are poorly reported in the medical literature. We report a case of analytically confirmed use of both methoxetamine and 3-methoxy-phencyclidine. A 27-year-old male presented 10 hours after insufflating an Internet-obtained powder. He was hypertensive, tachycardic, and demonstrated...

A Case of 3,4-Dimethoxyamphetamine (3,4-DMA) and 3,4-Methylenedioxymethamphetamine (MDMA) Toxicity with Possible Metabolic Interaction.

Journal of Psychoactive Drugs 2016 Michael A Darracq, Stephen L Thornton, Alicia B Minns et al. 2 citations

We present a case of "ecstasy" ingestion revealing 3,4-methylenedioxymethamphetamine (MDMA) and 3,4-dimethoxyamphetamine (3,4-DMA) and absence of cytochrome P450 (CYP)-2D6 MDMA metabolites. A 19-year-old presented following a seizure. Initial vital signs were normal. Laboratories were normal with the exception of sodium 127 mEq/L and urine drugs of abuse screen positive for amphetamines. Twelve...
