Notes: Carbinoxamine is a competitive histamine H1 receptor antagonist (Ki = 2.3 nM) and first generation antihistamine.{23220} It also competes with [3H]diltiazem, an L-type calcium channel blocker, for binding to the benzothiazepine site on rat cardiomyocytes (Ki = 1.08 nM).{41288} Carbinoxamine decreases negative inotropic activity in isolated guinea pig left atria by 76% (EC50 = 250 nM) and negative chronotropic activity in guinea pig spontaneously beating isolated right atria (EC50s = 250 and 480 nM, respectively) by 48% compared with control. Formulations containing carbinoxamine have been used in the treatment of allergic rhinitis.
