Background:

Diphenylpyraline is a first generation histamine H₁receptor antagonist (K_i= 20 nM in a radioligand binding assay using bovine cerebral cortex membranes).^1,2It also inhibits muscarinic acetylcholine receptors (K_i= 0.84 nM).²Diphenylpyraline (1 and 3 µM) inhibits contractions induced by prostaglandin E₁in isolated guinea pig ileum.³It inhibits ovalbumin-induced bronchoconstriction in ovalbumin-sensitized guinea pigs when administered intravenously at a dose of 20 µmol/kg.⁴Diphenylpyraline (14 mg/kg) also reduces dopamine uptake in rat nucleus accumbens.¹Formulations containing diphenylpyraline have been used in the treatment of allergic rhinitis.
