PY - 2014 T2 - Anesthesiology Core Review: Part One Basic Exam AB - Muscle relaxation caused by a muscle relaxant drug can be terminated spontaneously by diffusion, redistribution, metabolism, and excretion or via pharmacological antagonism using specific reversal agents known as cholinesterase inhibitors. Acetylcholinesterase is an enzyme found at the motor end plate. It functions by breaking down and reducing the amount of acetylcholine (ACh) at the nerve terminal. By inhibiting acetylcholinesterase, cholinesterase inhibitors indirectly increase the amount of ACh molecules that are available to compete with the nondepolarizing muscle relaxant for the binding sites of the ACh receptors.
