Det virker ved interaktion med ligand- styrede chloridionkanaler, specielt dem, der er styret af neurotransmitteren, gamma - aminosmørsyre (GABA), hvorved der blokeres for præ - og postsynaptisk transport af chloridioner over cellemembranen.
It acts by interacting with ligand-gated chloride channels, in particular those gated by the neurotransmitter gamma- aminobutyric acid (GABA), thereby blocking pre- and post-synaptic transfer of chloride ions across cell membranes.
