In Vivo	In a rat model of postoperative pain, L-745337 (40-80 μg, intrathecal) coadministered with intrathecal morphine (0.5 nmol) increases the withdrawal thresholds in a dose-dependent manner. Adding 80 μg L-745337 to 1 nmol morphine produces an antiallodynic effect greater than that of morphine at twice the dose. L-745337 (0-30 mg/kg, s.c.) combined with intrathecal morphine results in the same antiallodynic response as morphine alone[1]. L-745,337 shows anti-inflammatory activity, with the effective-dose of 0.4 mg/kg, and the maximal anti-inflammation dose of 5 mg/kg in arthritic rats[2].
