Amoxapine (pronounced: a-mox-a-peen.[3] Notable brand names include: Asendin, Asendis, Defanyl, Demolox. See here for more brand name information) is a tetracyclic antidepressant of the dibenzoxazepine family, though it is often classified as a secondary amine tricyclic antidepressant. It is the N-demethylated metabolite of Loxapine. It first received marketing approval in the US in 1992 (approximately thirty to forty years after most of the other tricyclic antidepressants were introduced in the US).[3]
