      Ramatroban (BAY u3405) is a thromboxane A(2) (TxA(2)) antagonist marketed for allergic rhinitis.;Target: TXA2 receptor; CRTh2Ramatroban (Baynas, BAY u3405), a thromboxane A(2) (TxA(2)) antagonist marketed for allergic rhinitis, has been shown to partially attenuate prostaglandin (PG)D(2)-induced bronchial hyperresponsiveness in humans, as well as reduce antigen-induced early- and late-phase inflammatory responses in mice, guinea pigs, and rats. PGD(2)-stimulated human eosinophil migration was shown to be mediated exclusively through activation of CRTH2, and surprisingly, these effects were completely inhibited by ramatroban. This is also the first report detailing an orally bioavailable small molecule CRTH2 antagonist. Our findings suggest that clinical efficacy of ramatroban may be in part mediated through its action on this Th2-, eosinophil-, and basophil-specific chemoattractant receptor [1].
