What Is Anticholinergic Syndrome?

Anticholinergic Syndrome (also known as Anticholinergic Syndrome) The term ″central anticholinergic syndrome″ refers to a psychosis or delirium that occurs suddenly as a result of the suppression of central cholinergic transmission. The following is taken from Haddad and Winchester’s Clinical Management of Poisoning and Drug Overdose (Fourth Edition), published in 2007.

The anticholinergic syndrome is caused by the competitive antagonism of acetylcholine at muscarinic receptors in the central and peripheral nervous systems. This toxidrome is characterized by an agitated (hyperactive) delirium characterized by bewilderment, restlessness, and picking at imagined things, all of which are typical of this condition.

  1. In febrile patients, blood and urine cultures are performed
  2. Analysis of serum chemistry and electrolyte levels, which may offer information as to the presence of intoxicating substances and co-ingestants.
  3. Patients with psychomotor agitation should have their creatine kinase (CK) levels checked to rule out the possibility of concomitant rhabdomyolysis.
