Lornoxicam is an orally bioavailable oxicam and non-steroidal anti-inflammatory drug (NSAID), with analgesic, anti-pyretic, anti-thrombotic and anti-inflammatory activities. Upon oral administration, lornoxicam binds to and inhibits the activity of the cyclooxygenase enzymes (COX) type 1 (COX-1) and type 2 (COX-2). This blocks COX-mediated signaling pathways, which leads to reduced prostaglandin and thromboxane production and decreased pain, fever and inflammation.

5 Pharmacology and Biochemistry
5.1 Pharmacology

Lornoxicam is a non-steroidal anti-inflammatory drug (NSAID) that belongs to the oxicam class. As with other NSAIDS, lornoxicam is a potent inhibitor of the cyclooxgenase enzymes, which are responsible for catalyzing the formation of prostaglandins (act as messenger molecules in the process of inflammation) and thromboxane from arachidonic acid. Unlike some NSAIDS, lornoxicam's inhibition of cyclooxygenase does not lead to an increase in leukotriene formation, meaning that arachidonic acid is not moved to the 5-lipoxygenase cascade, resulting in the minimization of the risk of adverse events.


5.2 MeSH Pharmacological Classification

Anti-Inflammatory Agents, Non-Steroidal

Anti-inflammatory agents that are non-steroidal in nature. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions. They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects. (See all compounds classified as Anti-Inflammatory Agents, Non-Steroidal.)


5.3 ATC Code

M - Musculo-skeletal system

M01 - Antiinflammatory and antirheumatic products

M01A - Antiinflammatory and antirheumatic products, non-steroids

M01AC - Oxicams

M01AC05 - Lornoxicam


5.4 Absorption, Distribution and Excretion

Absorption

Lornoxicam is absorbed rapidly and almost completely from the GI tract (90-100%).


5.5 Metabolism/Metabolites

Lornoxicam is metabolized completely by cyp 2C9 with the principal metabolite being 5'-hydroxy-lornoxicam and only negligible amounts of intact lornoxicam are excreted unchanged in the urine. Approximately 2/3 of the drug is eliminated via the liver and 1/3 via the kidneys in the active form.


Lornoxicam has known human metabolites that include 5'-Hydroxylornoxicam.

5.6 Biological Half-Life

3-5 hours


5.7 Mechanism of Action

Like other NSAIDS, lornoxicam's anti-inflammatory and analgesic activity is related to its inhibitory action on prostaglandin and thromboxane synthesis through the inhibition of both COX-1 and COX-2. This leads to the reduction of inflammation, pain, fever, and swelling, which are mediated by prostaglandins. However, the exact mechanism of lornoxicam, like that of the other NSAIDs, has not been fully determined.
