Ketamine is an N-methyl-D-aspartate (NMDA) receptor antagonist with prominent psychoactive effects in humans. This study evaluated whether the oral administration of haloperidol 5 mg would block the effects of an intravenous ketamine infusion (bolus of 0.26 mg/kg followed by 0.65 mg/kg per hour). Twenty healthy subjects completed 4 test days involving the(More)

The latter are coagonist sites associated with N-Methyl-D-Aspartate (NMDA) glutamate receptors. The central bioavailability of peripherally administered glycine has not been adequately characterized in humans. METHODS Healthy human subjects(More)
