Recent attention has focused on the glutamatergic system as a new, distinct target for depression treatment. Riluzole (Rilutek, Sanofi), an oral modulator of glutamate activity with neuroprotective and anticonvulsant properties, is currently approved by the United States Food and Drug Administration for treatment of amyotrophic lateral sclerosis (ALS). Preliminary studies using riluzole to treat depression in humans are promising, though larger, double-blinded controlled trials are needed.
