Scope note: Sustancias que no actúan como agonistas o antagonistas sino que afectan al complejo receptor-ionóforo del ÁCIDO GAMMA-AMINOBUTÍRICO. Los RECEPTORES DEL GABA-A parecen tener al menos tres sitios alostéricos donde actúan los moduladores: un sitio en el que actúan las BENZODIACEPINAS aumentando la frecuencia de apertura de los canales de cloro activados por ÁCIDO GAMMA-AMINOBUTÍRICO; un sitio en el que actúan los BARBITURICOS prolongando la duración de apertura del canal; y un sito en el que pueden actuar algunos esteroides. Los ANESTÉSICOS GENERALES actúan probablemente, al menos parcialmente, potenciando las respuestas GABAérgicas, pero no se incluyen aquí.

Scope note: Substances that do not act as agonists or antagonists but do affect the GAMMA-AMINOBUTYRIC ACID receptor-ionophore complex. GABA-A receptors (RECEPTORS, GABA-A) appear to have at least three allosteric sites at which modulators act: a site at which BENZODIAZEPINES act by increasing the opening frequency of GAMMA-AMINOBUTYRIC ACID-activated chloride channels; a site at which BARBITURATES act to prolong the duration of channel opening; and a site at which some steroids may act. GENERAL ANESTHETICS probably act at least partly by potentiating GABAergic responses, but they are not included here.
