Zafirlukast selectively and competitively inhibits leukotriene receptors, specifically receptors for leukotriene D4 and E4 (LTD4 and LTE4). Additionally, it competes for receptors with some components of slow-reacting substance of anaphylaxis (SRS-A). These substances have all been implicated in the inflammatory and bronchoconstrictive aspects of bronchial asthma.
In veterinary medicine, zidovudine may be useful for treating feline immunodeficiency virus (FIV) or feline leukemia virus (FeLV). While zidovudine can reduce the viral load in infected cats and improve clinical signs, it may not alter the natural course of the disease to a great extent.
