Comment: Gefapixant (MK‐7264, and formerly AF-219) is a P2X3 and P2X2/3 receptor antagonist. Experimental results have shown that gefapixant acts as a reversible allosteric antagonist, that exhibits preferential activity at closed channels.
Studies in rodent models have provided evidence that supports investigation of gefapixant as a novel treatment for chronic sensitisation conditions [7].
