Assemble to form cl- channel with GABA A receptor Activation of GABA receptors increases transmembrane CL conductance hyperpolarization of post synaptic membrane functional inhibition of the postsynaptic neuron Propofol … The pathophysiologic mechanism is still unknown. Laboratory investigations revealed that propofol might also protect MEDSimplified 263,871 views. Animal studies suggest that the mechanism of action of propofol as an anti-emetic is by inhibition of serotonin release by enhancing GABA activity, possibly by direct GABA-mediated action on 5HT 3-receptors in the area postrema/chemoreceptor trigger zone. Propofol works by increasing GABA mediated inhibitory tone in the CNS. The hypnotic effect of propofol is dose related, with small doses causing sedation and increased doses causing unconsciousness and apnea. Short-acting, lipophilic sedative/hypnotic; causes global CNS depression, presumably through agonist actions on GABAa receptors. The GABAergic system is also an important target for the non-genomic action of THs (20–26). The pKa is 11. 2 to 24 hours. The action of propofol involves a positive modulation of the inhibitory function of the neurotransmitter g-aminobutyric acid (GABA) through GABA A receptors.
