title: Riluzole decreases the abstinence syndrome and physical dependence in morphine-dependent mice.
abstract: The effects of the antiglutamatergic agent, riluzole, were examined on the antinociceptive action of morphine, on the induction of physical dependence, and on the expression of the abstinence syndrome to the opiate in mice. Morphine was administered as a single dose (200 mg/kg) of a slow-release preparation. Acute and chronic administration of riluzole decreased the analgesic response to morphine, the intensity of abstinence behavior (administered 30 min before a dose of naloxone), and the development of physical dependence (repeatedly administered during the period of chronic morphine treatment).
