3] have reported that the blocking of cox-2 activity in cAD rats by valdecoxib
(specific cox-2 inhibitor) resulted in better recovery of memory impairment, oxidative stress, and acetylcholine esterase activity compared to that of nonspecific cox blocker, naproxen, in a 25-day study indicating an important role of cox-2 on the colchicine induced memory impairments and stress parameters.
2]) provided the rationale for the development of COX-2 selective NSAIDs, such as celecoxib, rofecoxib, and valdecoxib
, for the management of pyrexia, relief of pain, and alleviation of inflammation with less gastrointestinal side effects .
