Description

Cross-talk between lipoxygenase (LO) and cyclooxygenase (COX) pathways has been observed in human osteoarthritic synovial explants which creates an arachidonic acid shunting phenomenon, stimulating interleukin-1β (IL-1β) synthesis. Licofelone is a dual inhibitor of COX and LO pathways, that decreases levels of prostaglandin E2, leukotriene B4, and lipoxins and prevents lipopolysaccharide-stimulated IL-1β expression.1 The IC50 values for inhibition of human thrombocyte COX and human 5-LO are 0.16 µM and 0.23 µM, respectively.2 Unlike other non-steroidal anti-inflammatory drugs, licofelone causes little or no damage to the gastric mucosa in rabbit parietal cells. This is presumably the result of licofelone’s affects on acid-secretory mechanisms, mediated by the inhibition of 5-LO activity.3
