TREATMENT OF ALLERGIC RESPONSE ON THE PART OF UPPER AIRWAYS BY MEANS OF A COMBINATION OD HISTAMINE RECEPTOR ANTAGONISTS

摘要

Relief from the symptoms of rhinitis is obtained by treatment with: (a) an antihistaminic effective amount of a histamine H1 receptor antagonist; together with (b) a sufficient amount of a histamine H3 receptor antagonist to provide a nasal decongestant effect. The components may be administered together in a single dosage form, or separately in the same or different dosage forms to maintain therapeutic systemic levels of both components.
