Description
Curator's Comment: description was created based on several sources, including https://www.drugbank.ca/drugs/DB01146 | https://www.ncbi.nlm.nih.gov/pubmed/42012 | https://www.ncbi.nlm.nih.gov/pubmed/1912125

Diphenylpyraline is an antihistamine that prevents but does not reverse, responses mediated by histamine alone. Diphenylpyraline antagonizes most of the pharmacological effects of histamine, including urticaria and pruritus. Also, diphenylpyraline may exhibit anticholinergic actions (as do most of the antihistamines) and may thus provide a drying effect on the nasal mucosa. Antihistamines such as diphenylpyraline used in the treatment of allergy act by competing with histamine for H1-receptor sites on effector cells. This reduces the effects of histamine, leading to a temporary reduction of allergy symptoms.

In Vivo Use Guide
Up to 6 mg daily in 3-4 divided doses.
Route of Administration: Oral
In Vitro Use Guide
Brain tissue was obtained at autopsy on 18 Japanese patients with chronic schizophrenia. The brain tissues were weighed, homogenized and centrifuged. The specific 3H-mepyramine binding to the brain tissues reached equilibrium values within 20 min after incubation at 25°C. Inhibition of the specific component of the 3H-mepyramine binding by Diphenylpyraline was then studied. The H1 antagonist diphenylpyraline (Ki=4.1nM) was potent competitors for the specific binding of 3H-mepyramine.
