Direct vs indirect cholinergic agonists

WebDirect-acting agonists bind to and activate muscarinic or nicotinic receptors. Indirect-acting agonists act by inhibiting acetylcholinesterase, which amplifies endogenous … WebAn indirect cholinergic agonist enhances the action potential of the postsynaptic neuron; a direct agonist increases the amount of acetylcholine (ACh) remaining at the synaptic cleft. D. An indirect cholinergic agonist binds to the acetylcholine (ACh) receptor; a direct agonist inhibits the binding process. A.
