A Fatal Colchicine Ingestion With Antemortem Blood Concentration.

Although there are multiple therapeutic uses for colchicine, it is particularly dangerous in the setting of overdose due to an irreversible mechanism of action combined with a narrow therapeutic window. Colchicine is an antimitotic agent that binds tubulin and inhibits microtubule polymerization. This produces a predictable sequence of toxicity beginning with gastrointestinal effects with progression to multiorgan system dysfunction.

Characteristics of Tianeptine Exposures Reported to the National Poison Data System - United States, 2000-2017.

Tianeptine (marketed as Coaxil or Stablon) is an atypical tricyclic drug used as an antidepressant in Europe, Asia, and Latin America. In the United States, tianeptine is not approved by the Food and Drug Administration (FDA) for medical use and is an unscheduled pharmaceutical agent* (1). Animal and human studies show that tianeptine is an opioid receptor agonist (2).

Trends in Teenagers' Nonopiod Substance Exposures Reported to Poison Control Centers, 2010-2015.

Objective: To describe current trends in nonopioid substance exposures and associated outcomes among teenagers nationwide.

Study Design: In this cross-sectional study, we used 2010-2015 data from the American Association of Poison Control Centers' National Poison Data System and Poisson tests to document trends in the rate of calls to poison control centers involving adolescents stratified by sex, exposures by substance category, proportion of intentional exposures, and severity of exposures.

Results: The number of calls per 1000 persons increased from 5.

Ranolazine overdose-induced seizures.

Ranolazine is a new anti-anginal medication that was approved by the US Food and Drug Administration (FDA) in 2006 for patients with symptomatic chronic angina despite optimized therapy. This paper presents a case report of a fifteen year old male patient admitted to the pediatric intensive care unit after ranolazine overdose ingestion. He had recurrent new onset seizures that are most likely due to ranolazine overdose.

Fatal bupropion overdose with post mortem blood concentrations.

We report five cases of fatal bupropion overdose with post mortem bupropion concentrations ranging from 3.1 to >20 mg/L. Four patients had ingested a sustained-release formulation of bupropion and had evidence of pill "bodies" in their stomach with significantly elevated blood bupropion concentrations.
