A depolarizing neuromuscular blocking agent is a form of neuromuscular blocker that depolarizes the motor end plate. [15] An example is succinylcholine . Depolarizing blocking agents work by depolarizing the plasma membrane of the muscle fiber, similar to acetylcholine .
Mivacurium chloride (formerly recognized as BW1090U81, BW B1090U or BW1090U) is a short-duration non-depolarizing neuromuscular-blocking drug [1] or skeletal muscle relaxant in the category of non-depolarizing neuromuscular-blocking drugs, [2] used adjunctively in anesthesia to facilitate endotracheal intubation [3] and to provide skeletal muscle relaxation during surgery or mechanical ...
Compared to depolarizing neuromuscular blockers, non-depolarizing neuromuscular blockers tend to have slower onset times and shorter duration of actions. [ 1 ] Aside from neuromuscular blocking agents, acetylcholinesterase inhibitors and butyrylcholinesterase inhibitors act on the neuromuscular junction to enhance neurotransmitter transmission ...
Pancuronium is a typical non-depolarizing curare-mimetic muscle relaxant. It competitively inhibits the nicotinic acetylcholine receptor at the neuromuscular junction by blocking the binding of acetylcholine. It has slight vagolytic activity, causing an increase in heart rate, but no ganglioplegic (i.e., blocking ganglions) activity.
Vecuronium is in the aminosteroid neuromuscular-blocker family of medications and is of the non-depolarizing type. [2] It works by competitively blocking the action of acetylcholine on skeletal muscles. [2] The effects may be reversed with sugammadex or a combination of neostigmine and glycopyrrolate. To minimize residual blockade, reversal ...
Gantacurium chloride (formerly recognized as GW280430A and as AV430A) is a new experimental neuromuscular blocking drug or skeletal muscle relaxant in the category of non-depolarizing neuromuscular-blocking drugs, used adjunctively in surgical anesthesia to facilitate endotracheal intubation and to provide skeletal muscle relaxation during surgery or mechanical ventilation.
Non-depolarizing neuromuscular blocking agents (i.e. Rocuronium, Vecuronium) interact with Ach receptor without activating the channel, as well as preventing the binding of acetylcholine to it. This blocks the signal propagation from the presynaptic neuron, and the severs the transduction of the excitatory signal from the synaptic cleft.
Its action leads to the accumulation of acetylcholine in the neuromuscular junction that compete with the non-depolarizing blocker agent bound to the acetylcholine receptors. By interfering with the breakdown of acetylcholine, neostigmine indirectly stimulates both nicotinic and muscarinic receptors. [10]
