Fenleuton (trade name Lofrin) is a drug that acts as a 5-lipoxygenase inhibitor and inhibits leukotriene ( LTB4, LTC4, LTD4, and LTE4) formation. It has been studied for potential use in veterinary medicine to treat respiratory diseases such as chronic obstructive pulmonary disease (COPD) in horses.^[2]
