Curator's Comment: description was created based on several sources, including https://www.drugbank.ca/drugs/DB06725

Lornoxicam (Xefo®) is a nonsteroidal anti-inflammatory drug of the oxicam class with analgesic, anti-inflammatory and antipyretic properties. It differs from other oxicam compounds in its potent inhibition of prostaglandin biosynthesis, a property that explains the particularly pronounced efficacy of the drug. The inhibition of the cyclooxygenase enzymes (COX-1 and COX-2) by lornoxicam (Xefo®) leads to desensitisation of peripheral nociceptors and consequently inhibition of inflammation. A central effect on nociception which seems to be independent of anti-inflammatory effects has also been suggested.

Sample Use Guides

In Vivo Use Guide

Pain: 8-16 mg lornoxicam (Xefo®) daily divided into 2 or 3 doses. Maximum recommended daily dose is 16 mg. Osteoarthritis and Rheumatoid arthritis: Initial recommended dose is 12 mg lornoxicam (Xefo®) daily divided into 2 or 3 doses. Maintenance dose should not exceed 16 mg lornoxicam daily.

Route of Administration: Oral

In Vitro Use Guide

In HEL/Mono Mac 6 human cells, lornoxicam showed a balanced inhibition of COX-1/-2 exhibiting the lowest IC50 (0.003 microM/0.008 microM) of the large panel of non steroidal antiinflammatory drugs tested. Similar results were obtained in the whole blood for COX-1/-2 (IC50 values of 0.13 microM for both isoenzymes). NO formation was dose-dependently inhibited by lornoxicam (IC50 of 65 microM) whereas piroxicam, diclofenac, ibuprofen, ketorolac and naproxen inhibited the NO formation markedly less. In stimulated human monocytic cells (THP-1), lornoxicam showed a marked inhibition of IL-6 formation (IC50 54 microM) while the formation ofTNF-alpha, IL-1beta and IL-8 was only moderately affected.
