Dipyrocetyl (2,3-diacetyloxybenzoic acid) is a drug used as an analgesics and antipyretics. Besides, was shown, that it may be useful in the treatment of acute lung injury (ALI) associated with acute respiratory distress syndrome (ARDS). Dipyrocetyl possesses the anticoagulation properties, which may contribute directly to improve tissue integrity as well as indirectly by the prevention of activation of pro-inflammatory cytokines. In addition, was made a suggestion, that the drug may function as an MMP inhibitor.

Nafamostat mesilate (NM), a synthetic serine protease inhibitor, has anticoagulant and anti-inflammatory properties. Nafamostat is approved and marketed in Japan. It relieves symptoms such as pain due to inflammation of the spleen. It improves visceral disorders and bleeding tendency caused by blood clotting tendency in the vessels. It prevents coagulation in the blood circuit during hemodialysis. It is usually used to improve acute symptoms of pancreatitis (acute pancreatitis, acute exacerbation phase of chronic pancreatitis, post-operative acute pancreatitis, acute pancreatitis after pancreatography, traumatic pancreatitis) and to prevent disseminated intravascular coagulation (DIC) and clotting of perfusing blood in extracorporeal blood circuit. Nafamostat mesilate significantly inhibits the release of platelet beta-thromboglobulin (beta TG) at 60 and 120 min. Nafamostat mesilate (NM) prevents any significant release of neutrophil elastase; at 120 min, plasma elastase-alpha 1-antitrypsin complex is 0.16 mg/mL in the NM group and 1.24 mg/mL in the control group. Nafamostat mesilate completely inhibits formation of complexes of C1 inhibitor with kallikrein and FXIIa.

Isoxicam is a nonsteroidal anti-inflammatory drug with long half-life. The major oxidative excretion product of isoxicam is the hydroxymethlyisoxazole metabolite, minor metabolites are open-ring sulfonamide and N-methylsaccharin. Isoxicam Is effective and well tolerated in all the major rheumatic diseases.

Etoricoxib is a selective COX-2 inhibitor, which is approved in Europe for the treatment of inflammatory disorders such as osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, acute pain conditions, gout and postoperative dental surgery pain.

Aceclofenac is a non-steroidal anti-inflammatory drug (NSAID) analog of Diclofenac. It is used for the relief of pain and inflammation in rheumatoid arthritis, osteoarthritis and ankylosing spondylitis. The dose is 100 mg twice daily, and should not be given to people with porphyria or breastfeeding mothers and is not recommended for children. Aceclofenac is a cytokine inhibitor. Aceclofenac works by blocking the action of a substance in the body called cyclo-oxygenase. Cyclo-oxygenase is involved in the production of prostaglandins (chemicals in the body which cause pain, swelling and inflammation). Aceclofenac is the glycolic acid ester of diclofenac. The incidence of gastric ulcerogenicity of aceclofenac has been reported to be significantly lower than that of other frequently prescribed NSAIDs: for instance, 2-fold less than naproxen, 4-fold less than diclofenac, and 7-fold less than indomethacin. Aceclofenac is metabolized in human hepatocytes and human microsomes to form [2-(2',6'-dichloro-4'-hydroxy- phenylamino)phenyl] acetoxyacetic acid as the major metabolite, which is then further conjugated.

Terofenamate (or etoclofene), the ethoxy methyl ester of N-(2,6-dichloro-m-tolyl)anthranilic acid, is a non-steroid anti-inflammatory agent. The drug showed a low level of toxicity and was well tolerated in animals.

Lonazolac is a nonsteroidal anti-inflammatory drug. The mononuclear cell response to a synovial stimulus can be abolished by very low concentrations of lonazolac. This blockade can be completely released by the addition of prostaglandin E2. Lonazolac appears therefore as an agent able in addition to modulate the immune response. The release of histamine from human basophils was significantly decreased after preincubation of the cells with lonazolac Ca. Preincubation of human polymorphonuclear leukocytes with lonazolac Ca led to an inhibition of leukotriene generation induced by either the Ca ionophore or opsonized zymosan. Lonazolac Ca affected different enzymes of the platelet activating factor metabolism. After pre- and post-treatment with lonazolac-Ca, the numbers of animals with lung metastases and the score of metastases significantly decreased. Lonazolac-Ca is indicated for the treatment of painful inflammatory rheumatic diseases of the joints and the spine. Acute irritation in osteoarthritis and spondylosis. Soft tissue rheumatism. Post-traumatic and postoperative pain and swelling states.

Fentiazac is a non-steroidal anti-inflammatory agent developed for the treatment of pain disorders. The drug was marketed under the name Norvedan, however, its current marketing status is unknown and supposed to be "discontinued".

Tilmacoxib [JTE 522] is an orally active, potent and highly selective cyclo-oxygenase-2 (COX-2) inhibitor. It entered phase II clinical trials for the treatment of Familial adenomatous polyposis, rheumatoid arthritis, osteoarthritis, and acute pain in Japan, but was discontinued in 2003.

Tinoridine is a non-steroidal anti-inflammatory and analgesic agent. This agent has been proved pharmacologically to show antiedematous and analgesic actions. The mechanism of the anti-inflammatory action of Tinoridine is attributed to its biomembrane stabilizing action particularly on the lysosomes which are related to cell or tissue damage at the time of inflammation through the release of hydrolytic enzymes. Tinoridine may produce gastrointestinal disorders (nausea, loss of appetite, diarrhea, and constipation), vertigo drowsiness, dry mouth and itching.
