What is the mechanism of action of pralidoxime?

Pralodoxime (protopam, 2pam) reactivates cholinesterase (mainly outside of the central nervous system) which has been inactivated by phosphorylation due to an organophosphate pesticide or related compound. Binds to the other half (the unblocked, anionic site) of the active site and then displaces the phosphate from the serine residue. (cleaves the phosphate - ester bond between organophosphate and acetylcholinesterase).

Name one distinguishing factor between calcium channel blocker overdose and beta blocker overdose and one way they are managed differently. 


Glucagon and lipid therapy are particularly useful for beta-blocker overdose, whereas IV calcium is especially beneficial in CCB overdose. Hyperglycemia in CCB overdose is a distinguishing diagnostic clue, while hypoglycemia may hint toward beta-blocker overdose. Both may require HDI and ECMO as advanced options in severe cases.
