question
ohm
answer
tells the resistance in the wire to the flow of electricity
question
ACh
answer
endogenous NT (not a good drug because rapidly metabolized); clinical use = produce complete miosis in eye surgery
question
Methacholine
answer
muscarinic selective, slightly longer duration of action; clinical use = bronchial airway hypersensitivity testing (diagnostic tool)
question
Carbachol
answer
carbamic acid derivative of ACh designed for longer duration of action (resists hydrolysis once bound to AChE); used in the eye to target the desired tissue, but not nicotinic/muscarinic selective; clinical use = produce complete miosis in eye surgery
question
Bethanechol
answer
added methyl to carbachol makes bethanechol; long-acting (resists hydrolysis) and selective for muscarinic receptors; bladder and GI hypotonia
question
Pilocarpine
answer
muscarinic agonist, binds AChE but resists hydrolysis (making it longer acting); used for treatment of open-angle glaucoma; natural product; can also be used clinically for Sjorgen’s syndrome
question
Cevimeline
answer
synthetic pilocarpine-like molecule; approved for Sjorgen’s syndrome
question
Oxotremorine
answer
muscarinic selective; long acting (resists AChE hydrolysis); clinical use = experimental model of Parkinson’s disease tremor
