Q

echothiophate

A

cholinesterase inhibitor - organophosphate

  • Well absorbed topically - used as insecticides
  • Well distributed into CNS
  • Phosphorlyated AChE active site - very stable
    • Undergoes aging - once aged you can’t get rid of the phos - you just have to make a new enzyme
    • Before aging you can use pralidoxime (2-PAM) to restore enzyme function

ganglionic blocking drug

lacks CNS effects

52
Q

mecamylamine

53
Q

pralidoxime (2-PAM)

A

cholinesterase regenerator - it binds to cholinesterase and inhibits it but not as tight as organophosphates so it can be used to knock them off if they havent aged yet
