diphenylpyraline Chemical Properties,Uses,Production
Definition
ChEBI: Diphenylpyraline is a member of the class of piperidines that is the benzhydryl ether derivative of 1-methyl-4-hydroxypiperidine. A sedating antihistamine, it is used as the hydrochloride for the symptomatic relief of allergic conditions including rhinitis and hay fever, and in pruritic skin disorders. It is also used as the teoclate salt (piprinhydrinate) as an ingredient in compound preparations for the symptomatic relief of coughs and the common cold. It has a role as a H1-receptor antagonist and a cholinergic antagonist. It is a member of piperidines and a tertiary amine.
Preparation
Diphenylpyraline synthesis via coupling of 4-hydroxy-1-methylpiperidine with benzhydrylbromide.
Mode of action
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.
