The cells and mediators that make up the inflammatory response have the pot
ential to injure tissues and contribute to the pathophysiology of many infl
ammatory diseases. Strategies to reduce neutrophil migration into sites of
inflammation and subsequent activation by inhibiting integrin-mediated adhe
sion hold promise for successful treatment of a variety of inflammatory dis
eases. New pharmacologic agents that specifically target prostanoid mediato
rs of inflammation by specifically inhibiting the activity of cyclooxygenas
e 2 are potent antiinflammatory agents with fewer gastrointestinal side eff
ects than nonspecific cyclooxygenase inhibitors. These areas of antiinflamm
atory research are rapidly yielding drugs with diverse future applications
in equine medicine.
