Abstract

Phencyclidine induces a psychotomimetic state by blocking neurotransmission at N-methyl-D-aspartic acid (NMDA) receptors. In a double- blind, placebo-controlled fashion, 14 medicated patients with chronic schizophrenia were treated with glycine, a potentiator of NMDA-receptor- mediated neurotransmission. Significant improvement in negative symptoms occurred in the group given glycine but not in the group given placebo, suggesting that potentiation of NMDA-receptor-mediated neurotransmission may represent an effective treatment for neuroleptic-resistant negative symptoms in schizophrenia.
