The invention relates to a novel application of a high-selectivity 5-hydroxytryptamine 5-HT2C
receptor agonist WAY163909. A molecular formula of the high-selectivity 5-hydroxytryptamine 5-HT2C
receptor agonist WAY163909 is C14H18N2, the molecular weight is 214.30600, and the high-selectivity 5-hydroxytryptamine 5-HT2C
receptor agonist WAY163909 is
white powder and has good water
solubility. The invention discloses the application of the high-selectivity 5-hydroxytryptamine 5-HT2C receptor agonist WAY163909 in preparation of medicines for inhibiting
addiction and withdrawl reactions of
opioid substances such as
morphine, or the application in preparation of the medicines for inhibiting the
addiction and withdrawl reactions of
morphine substances. According to the novel application disclosed by the invention, the latest researches show that WAY163909 (0.5-1.0mg / kg) can be used for significantly reducing the horizontal movement distance, horizontal movement speed and the withdrawal reactions of mice after
morphine-dependent mice are subjected to naloxone
precipitation. The novel application disclosed by the invention discovers that WAY163909 can be used for rescuing and treating the
addiction and withdrawl reactions produced by the
opioid substances such as morphine in
clinical treatment and can be used for treating the possible recurrences for the first time.
