Brompheniramine

Brompheniramine ((±)-Brompheniramine) is a potent and orally active antihistamine of the alkylamine class. Brompheniramine is a selective histamine H1 receptor antagonist with a Kd of 6.06 nM. Brompheniramine can block the hERG channels, calcium channels, and sodium channels with IC50s of 0.90 μM, 16.12 μM and 21.26 μM, respectively. Brompheniramine has anticholinergic, antidepressant and anesthetic properties and can be used for allergic rhinitis research[1][2][3][4].
