The Use of Physostigmine by Toxicologists in Anticholinergic Toxicity.

The anticholinergic toxidrome is well described and relatively common. Despite controversy, studies have shown that physostigmine is relatively safe and effective in reversing this toxidrome. We would expect toxicologists would be liberal in its use.

Benzodiazepine-associated atrioventricular block.
