COMBINATION HISTAMINE H1R AND H4R ANTAGONIST THERAPY FOR TREATING PRURITUS

摘要

Patients suffering from pruritus or itch may be effectively treated by administering a centrally acting histamine H1 receptor antagonist (e.g., diphenhydramine, triprolidine, hydroxyzine, pyrilamine, promethazine, or chlorpheniramine) and a histamine H4 receptor antagonist (e.g., 5-chloro-1H-indol-2-yl)-(4-methyl-piperazin-1-yl)-methanone).
