Question | Answer |
Muscarinic Agonists prototype? | Bethanechol |
Bethanechol Routes? | Po(will need larger dose) or SQ(has more adr effects) |
The antidote of Muscarinic Agonist toxicity? Why? | Atropine...it is a Muscarinic Antagonists and will indirectly give the opposite effect of Bethanechol. |
Muscarinic Antagonists prototype? | Atropine |
Atropine Routes? | Topical, PO, IV, IM, SQ |
The antidote of Muscarinic Antagonists toxicity? | Physostigmine...it is an cholinesterase inhibitor, will stop the breakdown of ACh. |
What two Muscarinic Antagonists drugs will tx OAB? | Tolterodine/Detrol (Get off the toilet) and Oxybutynin/Ditropan (stop the running) |
Cholinesterase Inhibitors Reversible prototype? | Neostigmine(short neo) |
Neostigmine Routes? | PO(need larger dose), SQ, IV, IM. note that it cannot cross the BBB |
What is the antidote for TX Cholinesterase Inhibitors Reversible OD? | Atropine...because it will stop the muscarinic receptor from being excessively stimulated. |
What are the four treatment steps from irreversible cholinesterase inhibitors? | 1.Ventilation
2.Atropine(stimulate muscarinic)
3.Pralidoxime(reverse effects)
4.Diazepam |
Prototype for Nondepolarizing neuromuscular blockers? | Tubocuraine |
Tubocuraine Routes? | IV, IM |
What is the antidote for Atropine OD | Physostigmine |
What is the prototype for Depolarizing neuromuscular blockers? | Succinylcholine |
Succinylcholine routes? | IV, IM |
What enzyme breaks down Succinylcholine? | pseudocholinesterase |
Cholinesterase inhibitors enhance the effects of Succinylcholine? | cholinesterase inhibitors delay the degradation of succinylcholine |
