Review-ready Target Rationale

Why P2X purinoceptor 3 matters

As of 2026-09-13

P2X purinoceptor 3 is reviewed as P2X purinoceptor 3 (UniProt P56373); P2X purinoceptor 3 shows approved-linked disease relevance led by Cough. 5 more disease programs remain visible in the same review block.; 3 linked drugs keep this evidence frame grounded.; the current evidence base includes 2 approved drugs, 5238 compounds, and 109 assays, with lead potency reaching pChEMBL 10.3.

Disease context
Cough

P2X purinoceptor 3 shows approved-linked disease relevance led by Cough. 5 more disease programs remain visible in the same review block. 3 linked drugs keep the rationale reviewable. 5 additional disease programs remain visible in the same card. Linked drugs include CAMLIPIXANT, GEFAPIXANT, GEFAPIXANT CITRATE.

Start review with Cough because it currently carries approved-linked support. Linked drugs include CAMLIPIXANT, GEFAPIXANT, GEFAPIXANT CITRATE. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
