Lornoxicam

Absorption

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

Description

Lornoxicam is a nonselective NSAID for oral and intravenous administration. It has been available for human use since two decades and there is a growing body of evidence supporting its efficacy and tolerability for management of acute pain.
Xefo, a member of the oxicam family of nonsteroidal antiinflammatory agents, was launched in Denmark for mild to moderate pain and inflammation. A seven step synthesis, beginning with 2,5-dichlorothiophene, provides access to this compound. It inhibits prostaglandin synthesis at the level of cyclooxygenase (Cox1 :Cox2 = 0.6) but does not inhibit 5-lipoxygenase. Xefo did not increase serum levels of pepsinogen I (an indicator of gastric mucosal status) and readily penetrates perivascular interstitial spaces including synovial fluid. It is as effective as morphine, meperidine and tramadol in relieving post operative pain and as efficient as other NSAlDs in relieving the symptoms of osteoarthritis and rheumatoid arthritis. It is 100 times more potent than Tenoxicam in inhibiting PGD2 and more active than indomethacin (6x) or piroxicam (10x) in preventing arachadonic acid influenced lethality in mice. Xefo has inhibitor effects on spinal nocicceptive processing presumably via release of endogenous opiods and evidence suggests it is good for migraine.

The Uses of Lornoxicam

Lornoxicam belongs to the oxicam class. It has anti-inflammatory and antipyretic properties. Lornoxicam prevents the synthesis of prostaglandin (PG) by inhibiting cyclo-oxygenase. It is used to relieve various types of symptoms associated with osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, acute sciatica and low back pain.Lornoxicam is approved for use in Japan.
Lornoxicam has been used as a drug in melanin binding study with cassette dosing and rapid equilibrium dialysis inserts. Lornoxicam differs from other oxicam compounds in its potent inhibition of prostaglandin biosynthesis, a property that explains the particularly pronounced efficacy of the drug.

Indications

For the treatment of acute mild to moderate pain, as well as pain and inflammation of the joints caused by certain types of rheumatic diseases.

Background

Lornoxicam (chlortenoxicam) is a new nonsteroidal anti-inflammatory drug (NSAID) of the oxicam class with analgesic, anti-inflammatory and antipyretic properties. Lornoxicam differs from other oxicam compounds in its potent inhibition of prostaglandin biosynthesis, a property that explains the particularly pronounced efficacy of the drug. Lornoxicam is approved for use in Japan.

What are the applications of Application

Lornoxicam is a cyclooxygenase inhibitor

Pharmacokinetics

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.

Metabolism

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.
