Urinary trypsin inhibitor attenuates the development of neuropathic pain following spinal nerve ligation.

Following nerve injury, inflammatory and algesic mediators are released. This neuroinflammatory outbreak causes neuronal damage and chronic neuropathic pain. Urinary trypsin inhibitor (ulinastatin, UTI), which has anti-inflammatory properties and neuroprotective effects, is used to lower the levels of inflammatory factors during surgery.
