Pralidoxime methyl sulfateProduct ingredient for Pralidoxime
- Name
- Pralidoxime methyl sulfate
- Drug Entry
- Pralidoxime
Pralidoxime is an antidote to organophosphate pesticides and chemicals. Organophosphates bind to the esteratic site of acetylcholinesterase, which results initially in reversible inactivation of the enzyme. If given within 24 hours,after organophosphate exposure, pralidoxime reactivates the enzyme cholinesterase by cleaving the phosphate-ester bond formed between the organophosphate and acetylcholinesterase.
