Figure 3. Hotplate latencies versus time as a measure of (A) sensory function versus time and (B) motor function scores versus time for the following formulations: bupivacaine microspheres (B-Ms) (n = 4), B-Ms with 0.14 mg/kg dexamethasone in the injection fluid (n = 7), and B-Ms injected with both 1.4 mg/kg cortexolone and 0.14 mg/kg dexamethasone in the injection fluid (n = 8).
