Introduction
Ornopain IM/IV Injection 8 mg/2 ml (chlortenoxicam) is a new nonsteroidal anti-inflammatory drug (NSAID) of the oxicam class with analgesic, anti-inflammatory and antipyretic properties. Ornopain IM/IV Injection 8 mg/2 ml differs from other oxicam compounds in its potent inhibition of prostaglandin biosynthesis, a property that explains the particularly pronounced efficacy of the drug. Ornopain IM/IV Injection 8 mg/2 ml is approved for use in Japan.
Uses
Ornopain IM/IV Injection 8 mg/2 ml is an NSAID indicated in the treatment of mild to moderate pain, as well as rheumatoid arthritis and osteoarthritis.
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.
Associated Conditions
Pharmacodynamics
Ornopain IM/IV Injection 8 mg/2 ml 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.
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.
Absorption
Ornopain IM/IV Injection 8 mg/2 ml is absorbed rapidly and almost completely from the GI tract (90-100%).
Protein Binding
Ornopain IM/IV Injection 8 mg/2 ml is 99% bound to plasma proteins (almost exlusively to serum albumin).
