Glycine reuptake inhibitor


A glycine reuptake inhibitor is a type of drug which inhibits the reuptake of the neurotransmitter glycine by blocking one or more of the glycine transporters. Examples of GRIs include bitopertin, Org 24598, Org 25935, ALX-5407, and sarcosine, which are selective GlyT1 blockers, and Org 25543 and N-arachidonylglycine, which are selective GlyT2 blockers. Some weak and/or non-selective GlyT blockers include amoxapine and ethanol.
