Hcn1 receptors ketamine
WebOct 2, 2012 · Although most of the effects of ketamine have been ascribed to its function as a glutamate receptor antagonist, because ketamine is also an HCN1 channel antagonist ( 4 ), it is possible that inhibition of HCN1 channels could contribute to or be responsible for its antidepressant effects. Kim et al. ( 6) provide evidence to support this notion. WebKetamine is a noncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist, and it blocks HCN1 receptors. However, at higher doses it may also bind to the opioid mu …
