Gut decontamination in the poisoned patient.

Poisoning management includes gastrointestinal decontamination strategies to decrease the burden of poison entering the body and change the expected severe toxicity expected to a less toxic, more favourable outcome. Common modalities are orogastric lavage, oral-activated charcoal and whole-bowel irrigation. Endoscopic retrieval and laparotomy are rare options reserved for severe ingestions and body packers.

Amitriptyline accumulation in tissues after coated activated charcoal hemoperfusion-a randomized controlled animal poisoning model.

Amitriptyline poisoning (AT) is a common poisoning, and AT possess the ability to promote life-threatening complications by its main action on the central nervous and cardiovascular systems. The pharmacokinetic properties might be altered at toxic levels compared to therapeutic levels. The effect of coated activated charcoal hemoperfusion (CAC-HP) on the accumulation of AT and its active metabolite nortriptyline (NT) in various tissues was studied in a non-blinded randomized controlled animal trial including 14 female Danish Land Race piglets.

Potential pharmacobezoar formation of large size extended-release tablets and their dissolution - an in vitro study.

Objective: Extended release (ER) tablets/capsules in massive ingestion overdoses are prone to form pharmacobezoars potentially increasing the risk of late-appearing toxic effects and prolonged symptoms. Oral activated charcoal is often sufficient to prevent drug absorption, but in a recent massive ingestion of highly toxic substances, prior orogastric lavage might be considered. The disintegration characteristics of ER preparations in overdose situations is valuable to understand if the time line and course of the intoxication might be prolonged, but information on these characteristics are unavailable.
