Cyclizine Hydrochloride from Japan
Cyclizine hydrochloride is a piperazine-based antihistamine used mainly for preventing motion sickness and treating vertigo/nausea. Its heterocyclic structure with piperazine ring qualifies it under HTS 2933.59.21.00 as an aromatic antihistamine anti-nauseant. Chapter notes confirm classification for separate chemically defined compounds with nitrogen hetero-atoms.
