Depolarising muscles relaxants activate the muscle briefly, before blocking it.
Receptor blockers
Substances that compete with ACh, for the receptors on a muscle cell can be either depolarising, or non-depolarising.Other mechanisms
Botulinum toxin, marketed as Botox for facial wrinkle removal, works by stopping the release of ACh from the presynaptic neuron.
