Tepoxalin is a compound that acts as a dual inhibitor, targeting both COX and 5-lipoxygenase (5-LO) enzymes. Additionally, it selectively inhibits the activity of 12-lipoxygenase (12-LO) while not affecting 15-lipoxygenase (15-LO). By exerting its inhibitory effects, tepoxalin effectively decreases the production of thromboxane B2 (TXB2) and leukotriene B4 (LTB4) in human peripheral blood mononuclear cells (PBMCs) stimulated by the calcium ionophore A23187. Furthermore, it displays the ability to mitigate epinephrine-induced platelet aggregation in human platelet-rich plasma (PRP).
