Sumario:Antimuscarinic drug toxicity is a common pediatric emergency, which produces central and peripheral symptoms. Treatment of agitation and hyperactive antimuscarinic delirium, with first-line agents like cholinesterase inhibitors or benzodiazepines, is imperative to prevent severe toxicity. Intravenous physostigmine salicylate is a cholinesterase inhibitor that is commonly used to treat central antimuscarinic delirium. Its chemical structure facilitates crossing of the blood–brain barrier. Overlapping nationwide physostigmine and benzodiazepine shortages have prompted consideration of therapeutic alternatives. Rivastigmine is a long-acting cholinesterase inhibitor with a similar chemical structure to physostigmine. It represents a potential therapeutic option for antimuscarinic delirium. Rivastigmine offers potential benefits over physostigmine including a longer duration of action, slower rate of central nervous system penetration, more favorable side effect profile, and availability in multiple formulations. A paucity of literature exists describing the use of rivastigmine for central antimuscarinic delirium. We describe the effective use of oral rivastigmine in a child with central antimuscarinic delirium.
