What type of drug is pralidoxime?

Pralidoxime (2-pyridine aldoxime methyl chloride) or 2-PAM, usually as the chloride or iodide salts, belongs to a family of compounds called oximes that bind to organophosphate-inactivated acetylcholinesterase. It is used to treat organophosphate poisoning in conjunction with atropine and either diazepam or midazolam.

Why is pralidoxime used with atropine?

What is the mechanism of action of atropine?

Atropine disappears rapidly from the blood and is distributed throughout the various body tissues and fluids.

Does atropine slow heart rate?

Atropine has complex effects on heart rate: At low doses, atropine blocks M1 acetylcholine receptors in the parasympathetic ganglion controlling the SA node. This decreases heart rate (Bernheim 2004). At higher doses, atropine also blocks M2 acetylcholine receptors on the myocardium itself.
