Mechanism of action

By blocking the reuptake of glycine at the presynaptic terminal, bitopertin increases glycine concentration in the synaptic cleft. Glycine acts as a co-agonist at NMDA receptors, and elevated levels potentiate glutamatergic neurotransmission, which is hypothesized to improve cognitive and negative symptoms in schizophrenia and other neuropsychiatric disorders.
