Ketamine potentiates 5-HT3 receptor-mediated currents in rabbit nodose ganglion neurones

Br J Pharmacol. 1991 Jul;103(3):1623-5. doi: 10.1111/j.1476-5381.1991.tb09837.x.

Abstract

The interaction of ketamine with the 5-HT3 receptor of rabbit nodose ganglion neurones is described. Ketamine (3-30 microM) enhanced 5-HT3 receptor-mediated currents recorded under voltage-clamp conditions. This action did not appear to be related to the known effect of ketamine of inhibiting 5-HT uptake.
