Nerve membrane stabilization

"Nerve membrane stabilization" refers to the reduction or elimination of action potential propagation in neuronal membranes, most often via the inhibition of voltage-gated sodium channels. Drugs exhibiting this effect decrease membrane permeability to sodium ions, thus blocking nerve conduction and producing therapeutic effects such as local anesthesia or cardiac rhythm stabilization. Various molecules—including local anesthetics, some beta-blockers, and antiarrhythmic agents—produce membrane stabilization by interacting with ion channels essential for nerve and muscle excitability. The term does not designate a discrete molecular target, but rather a collective functional change induced by different drugs or endogenous factors.
