Description: Saredutant, aslo known as SR-48968, is a NK2 receptor antagonist for the treatment of major depressive disorder. Saredutant has both antidepressant-like effects and synergizes with desipramine in an animal model of depression. Saredutant, ameliorates stress-induced conditions without impairing cognition. SR 48968 specifically depresses neurokinin A- vs. substance P-induced hyperalgesia in a nociceptive withdrawal reflex. SR 48968 inhibits citric acid-induced airway hyperresponsiveness in guinea pigs.
