GABA-β receptors also produce sedative effects. (wikipedia.org)
These drugs act instead as positive allosteric modulators (PAMs) and while they do bind to the GABA receptors, they bind to an allosteric site on the receptor and cannot induce a response from the neuron without an actual agonist being present. (wikipedia.org)
However, some general anaesthetics like propofol and high doses of barbiturates may not only be positive allosteric modulators of GABA-A receptors but also direct agonists of these receptors. (wikipedia.org)
