title: Molecular and physicochemical aspects of local anesthetics acting on nicotinic acetylcholine receptor-containing membranes.
abstract: Local anesthetics inhibit the ion channel activity of nicotinic acetylcholine receptors in a noncompetitive fashion. This inhibitory action is ascribed to two possible inhibitory mechanisms: an open-channel-blocking mechanism and/or an allosteric process where the drug binds either to the closed channel or to other nonluminal sites, respectively.
