An inflammatory pain model was optimized in rats so that PGE(2) levels in the cerebrospinal fluid (CSF) could be directly correlated to the nociceptive response. Since efipladib appears to have limited permeation of the blood brain barrier, we used this compound to determine the extent of pain reversal resulting primarily from peripheral, but not central, inhibition of the arachidonic acid (AA) pathway.
