Correct
Answer & Explanation:

The H1-receptor antagonists, or antihistamines, are divided into first- and second-generation agents based on the sedating activities of the agents secondary to CNS access and distribution.
(1) The classic, first-generation antihistamines include the chemical classes of
(a) the ethanolamines: carbinoxamine (Arbinoxa, Palgic), clemastine (Tavist), diphenhydramine (Benadryl), and doxylamine (Unisom);
(b) the alkylamines: brompheniramine (Dimetane, Brovex, Lodrane), chlorpheniramine (Chlor-Trimeton), dexbrompheniramine (Drixoral, Ala-Hist IR), dexchlorpheniramine (Polaramine), and triprolidine (Zymine, Actidil, Tripohist);
(c) the piperazine: hydroxyzine (Atarax, Vistaril);
