The invention concerns novel pharmaceutical compositions and methods for the treatment of allergic rhinitis. More specifically, the invention concerns the inhibition of histamines, which is one of the primary causes of allergic rhinitis in human patients. The inventive pharmaceutical compositions include a carbonyl group-containing moiety, optionally in acidic medium, that combines with histamine to block histamine activity and thus reduce undesirable physiological effects of histamine in the body.
