HOW DO ANTICHOLINERGIC TOXICITY ANTIDOTES WORK?

Anticholinergic toxicity antidotes are drugs used to treat the adverse effects of anticholinergic toxicity that affect the central nervous system. The main causes of anticholinergic toxicity include:

  • Drug misuse
  • Overdose of drugs with anticholinergic activity
  • Drug abuse with cocaine and heroin, known to be contaminated with anticholinergic drugs such as hyoscine and atropine
  • Intentional or accidental ingestion of plants containing belladonna alkaloids
  • Topical application

Medications with anticholinergic activity include:

Naturally occurring anticholinergic drugs include:

  • Atropine
  • Hyoscine
  • Hyoscyamine

Anticholinergic toxicity can cause the following symptoms:

Antidotes such as physostigmine may be given to reverse the damaging effects of anticholinergic toxicity. These drugs directly inhibit the acetylcholinesterase enzyme in the central nervous system. Acetylcholinesterase enzymes break down acetylcholine (a naturally occurring neurohormone) into acetic acid and choline. Blocking the acetylcholinesterase can result in an increased level of acetylcholine. Acetylcholine reverses the harmful effects of anticholinergic toxicity.
