Hyperpathia, hyperalgesia, and allodynia are three manifestations of central sensitization, a condition in which a higher than necessary degree of activity is triggered in the central nervous system.

Some of the central molecular mechanisms that lead to hyperalgesia and allodynia after peripheral tissue injury involve the spinal dorsal horn transient receptor potential vanilloid 1 (TRPV1).

As demonstrated in a novel mouse model, the mouse version of the drug (mIL-1 Trap) both prevented and relieved ankle joint synovitis and hyperalgesia induced by monosodium urate (MSU) crystals.
