title: The actions of ivermectin on cultured chick spinal cord neurons.
abstract: The effects of ivermectin (IVM) on cultured chick spinal neurons sensitive to GABA agonists were investigated. IVM caused a change of membrane potential which was associated with an increase in membrane conductance, apparently reversed at about -40 mV and weakened by repetitive application. Furthermore, this agent did not have any effects on either the actions of GABA agonists on neurons or [3H]GABA efflux from those cells. These results suggest that IVM increases membrane conductance through sites which are different from GABA recognition sites.
