  • Gefapixant citrate is an orally active and potent purinergic P2X3 receptor (P2X3R) antagonist, with IC50 values of ~30 nM versus recombinant hP2X3 homotrimers and 100-250 nM at hP2X2/3 heterotrimeric receptors. Gefapixant citrate can be used for the research of chronic cough and knee osteoarthritis[1][2][3].

Target

IC50: ~30 nM (recombinant hP2X3 homotrimers), 100-250 nM (hP2X2/3 heterotrimeric receptors)[1].

In Vitro Gefapixant citrate displays no inhibitory impact on any non-P2X3 subunit containing receptors (IC50 values >10,000 nM at recombinant homotrimeric hP2X1, hP2X2, hP2X4, rP2X5 and hP2X7 channels)[1].
In Vivo Gefapixant citrate (7d bid, orally) attenuates the weight bearing laterality with complete reversal of apparent hyperalgesia at the two higher doses in a rat model of knee osteoarthritis (14d following intra-articular administration of monoiodoacetate)[2].
