When administered at anesthetic doses (~100 μM), ketamine produces immunosuppressant effects via downregulation of TNF-α and IL-6 synthesis [239–242]. In a model of early-life stress, antidepressant doses of ketamine were able to block maternal separation-induced increases in TNF-α, IL-1, and IL-6 [ 243 ].Abstract. The history of ketamine begins in 1962, when Calvin Stevens of the pharmaceutical laboratory Parke-Davis synthesizes it from phencyclidine, a molecule with psychodysleptic, hallucinogenic and dissociative properties.
