Pirquinozol (SQ-13,847) is a drug which was investigated as an antiallergen and antiasthmatic agent in the early 1980s but was never marketed.[1][2][3] Notably, pirquinozol is not an antihistamine, though it does block the release of histamine evoked by allergens, and it does not bind to β-adrenergic receptors either.[1]
