Structural and binding studies of C-terminal half (C-lobe) of lactoferrin protein with COX-2-specific non-steroidal anti-inflammatory drugs (NSAIDs).

Three COX-2-specific non-steroidal anti-inflammatory drugs (NSAIDs), etoricoxib, parecoxib, and nimesulide are widely prescribed against inflammatory conditions. However, their long term administration leads to severe conditions of cardiovascular complications and gastric ulceration. In order to minimize these side effects, C-terminal half (C-lobe) of colostrum protein lactoferrin has been indicated to be useful if co-administered with NSAIDs.

The structural basis for the prevention of nonsteroidal antiinflammatory drug-induced gastrointestinal tract damage by the C-lobe of bovine colostrum lactoferrin.

Nonsteroidal antiinflammatory drugs (NSAIDs), due to their good efficacy in the treatment of pain, inflammation, and fever, are among the most prescribed class of medicines in the world. The main drawback of NSAIDs is that they induce gastric complications such as peptic ulceration and injury to the intestine. Four NSAIDs, indomethacin, diclofenac, aspirin, and ibuprofen were selected to induce gastropathy in mouse models.
