Antihistamines used in the treatment of allergy act by competing with histamine for H1-receptor sites in effector cells. They thereby prevent, but do not reverse, responses mediated by histamine alone. Antihistamines antagonize, in varying degrees, most of the pharmacological effect of histamine, including urticaria and pruritus. Also, the anticholinergic actions of most antihistamines provide a drying effect on the nasal mucosa. Antihistamines prevent responses to acetylcholine that are mediated via muscarinic receptors.
