Of these Meloxicam (Mobic. Cyclooxygenase Isozymes: The Biology of Prostaglandin Synthesis and Inhibition. A. Treatment of Inflammatory Diseases. NSAIDs are currently used as first- line therapeutics in the treatment of osteoarthritis (OA), rheumatoid arthritis (RA), systemic lupus erythematosis, and other inflammatory syndromes. In each case, NSAID treatment is palliative rather than disease modifying. NSAIDs reduce inflammation and pain in these syndromes. In the short period of 8 years after the discovery of COX- 2, selective inhibitors of this enzyme were developed for use in RA, OA, and for pain relief. Even before the discovery of COX- 2, pharmaceutical companies were searching for anti- inflammatory drugs that would have less damaging effects on the stomach than existing therapies. In the 1. 98. 0s, these experiments resulted in the development of three drugs with anti- inflammatory activity but with very little inhibitory effect on PG production by the stomach. Nimesulide, etodolac, and meloxicam emerged from preclinical studies as anti- inflammatory compounds with less damaging effects on the stomach than established NSAIDs. After the discovery of COX- 2 in 1. Ja olen tällä hetkellä Mobic. 75-year-old men with no comorbidities had a. This subsequently lost statistical significance as was recorded. 7-year follow up study. Kujubu et al., 1. Xie et al., 1. 99. COX- 2 compared with COX- 1; however, after the cloning of COX- 2, inhibitors were designed with an even greater selectivity for COX- 2. Selectivity for the inducible isoform was established by comparing inhibitory potency against COX- 1 measured as the IC5. COX- 2 in isolated enzymes, cultured cells, or in the whole blood assay. Slightly different measurements of selectivity were obtained in each system, but the relative values between drugs and their order of potency generally remained the same. 1587 A Year Of No Significance Mobic 15The most reproducible estimates of selectivity have been obtained by comparing inhibitory potency on recombinant human enzymes or by measuring the selectivity with the human whole blood assay (Patrignani et al., 1. The latter is considered to resemble most closely the clinical situation in patients taking NSAIDs. Blood proteins are present so that drug binding to protein is accounted for and endogenous human enzymes are used. The inhibitory potency against COX- 1 is measured on platelets in clotting blood, whereas potency for inhibition of COX- 2 is estimated in blood monocytes previously incubated with endotoxin to induce COX- 2. The modified William Harvey whole blood assay (Warner et al., 1. A5. 49 cells, instead of blood monocytes, incubated with IL- 1 and added to human blood for estimation of activity against COX- 2. Nimesulide, like etodolac, was developed in the 1. Helsinn Healthcare SA to a number of other pharmaceutical companies. It has been sold over the counter in Italy since 1. European and South American countries. Chemically, nimesulide has a sulfone structure and resembles structurally the selective COX- 2 inhibitors developed in the 1. Fig. 1. 1). Early experimental studies in rats demonstrated that at anti- inflammatory doses that reduced carrageenan- induced paw edema, nimesulide had no effect on gastric PG levels and did not cause bleeding of the gastric mucosa (Carr et al., 1. Nakatsugi et al., 1. Its selective inhibition of COX- 2 has been demonstrated in vitro using purified enzymes; the IC5. COX- 1 was 5- fold greater than that for COX- 2 (Barnett et al., 1. Cullen et al., 1. In the human whole blood assay (Patrignani et al., 1. COX- 2 in monocytes than COX- 1 in platelets (IC5. COX- 2 = 0. 5 . A single oral dose (1. COX- 2 and platelet COX- 1 ex vivo by 9. COX- 1 activity may not be sufficient to affect platelet aggregation or bleeding time (Panara et al., 1. A reduction of 2. TXB2 levels with nimesulide had no effect on arachidonic acid- induced platelet aggregation in humans in vivo; however, reducing TXB2 levels by 9. Shah et al., 1. 99. PGE2 production from gastric biopsies was also reduced by 7. Comparing gastroduodenal damage with nimesulide or naproxen in 3. P < 0. 0. 00. 1) (Shah et al., 2. The relatively short half- life of nimesulide (1. Bree et al., 1. 99. Bernareggi, 1. 99. PG synthesis in the gastric mucosa to recover before their protective effect has worn off. Estimates of rate ratios for peptic ulcer, gastrointestinal hemorrhage, or perforation placed the incidence for nimesulide below that for diclofenac and naproxen (Menniti- Ippolito et al., 1. Other epidemiological analyses (Garcia Rodriguez et al., 1. Porto et al., 1. 99. This surprising result may be due to the small numbers of patients in these studies and the wide range of confidence intervals of the estimates (Rainsford, 1. The therapeutic efficacy of nimesulide has been demonstrated in clinical trials in at least 5. OA (L. Its action is rapid in onset because it is effective within 2. Ragot et al., 1. 99. Pulkkinen, 1. 98. Of an estimated 2. Helsinn Healthcare SA (Rainsford, 1. March 2. 00. 2, nimesulide was withdrawn from the Finnish market because of unacceptable hepatoxicity and then in May 2. Spanish market. Data from the Spanish Pharmacovigilance System reported a higher rate of hepatic injury with nimesulide than with other NSAIDs during the 1. Maci. This supports the concept that aspirin- induced asthma is caused by inhibition of COX- 1 (Bianco et al., 1. Senna et al., 1. 99. Gryglewski, 1. 99. Bennett, 2. 00. 0). Prolonged treatment with nimesulide has delayed premature labor for up to 3. Sawdy et al., 1. 99. A number of actions of nimesulide demonstrated in vitro may contribute to its therapeutic anti- inflammatory effects in vivo. These include, inhibition of neutrophil function (Ottonello et al., 1. Capecchi et al., 1. Maffei et al., 1. Barracchini et al., 1. Berti et al., 1. 99. Bennett, 2. 00. 1; Mukherjee et al., 2. Etodolac has been available for clinical use in Europe and North America for many years. It has a pyranocarboxylic acid structure (Fig. Jones, 2. 00. 1). On human recombinant enzymes, etodolac had an 1. COX- 2 than for COX- 1 and an 8- fold selectivity for COX- 2 over COX- 1 in the human whole blood assay (Glaser, 1. This was confirmed in the modified William Harvey whole blood assay in which a 1. COX- 2 over COX- 1 was recorded (Warner et al., 1. In various randomized double- blind clinical trials in more than 2. OA patients lasting from 6 to 1. Platt, 1. 98. 9; Bacon, 1. Porzio, 1. 99. 3; Schnitzer and Constantine, 1. In a 1. 2- week randomized double blind study in RA, 6. Lightfoot, 1. 99. Delcambre, 1. 99. A long- term double blind trial lasting for 3 years with 1. RA patients, showed that 3. Neustadt, 1. 99. 7). The cumulative incidence of gastrointestinal (GI) ulcers or bleeds over the 3 year period amounted to two patients on each dose of etodolac (0. The safety of etodolac, particularly its toxicity to the GI tract has been evaluated in 2. Lightfoot, 1. 99. Schattenkirchner, 1. The incidence of GI ulceration and bleeding in patients receiving etodolac was 0. Studies in healthy volunteers reported that fecal blood loss with etodolac was similar to that seen with placebo, but less than the GI blood loss with aspirin, ibuprofen, naproxen, or indomethacin (Ryder et al., 1. Salom et al., 1. 98. Arnold et al., 1. Lanza and Arnold, 1. Leese, 1. 99. 2). A 7- day endoscopic study by Lanza et al. Only 3 of 1. 5 patients receiving etodolac developed upper GI mucosal lesions, whereas 8 of 1. GI tract. Data from the Arthritis, Rheumatism and Aging Medical Information System (ARAMIS) indicates that etodolac (on the basis of data for 8. NSAIDs that are not associated with serious GI bleeds or other significant events requiring hospitalizations. The renal toxicity of etodolac has been reviewed in 1. OA or RA. The trials lasted from 4 to 5. The risk of renal function impairment was no greater among patients treated with etodolac than those receiving placebo (Shand et al., 1. Meloxicam also emerged as a potential new drug from a preclinical search for an anti- inflammatory drug with a low propensity to damage the stomach mucosa. It was first registered in 1. OA, RA, and ankylosing spondylitis. Its chemical structure is that of an enolcarboxamide (Fig. COX- 2 inhibitor since 1. The 5- methyl group on the thiazolyl ring of meloxicam can enter the side pocket at the active site of COX- 2. Meloxicam has a 1. COX- 2 in microsomal preparations of human recombinant enzymes (Churchill et al., 1. Pairet et al., 1. COX- 2 in the human whole blood assay (Patrignani et al., 1. Warner et al., 1. William Harvey whole blood assay, a 2. COX- 2 over COX- 1 has been reported (Warner et al., 1. In animal studies, meloxicam had potent anti- inflammatory activity with less inhibition of PGE2 production in the stomach and kidneys than standard NSAIDs (Engelhardt, 1. Meloxicam was also more potent in reducing edema of the inflamed rat paw than indomethacin, piroxicam, diclofenac, or naproxen (Engelhardt et al., 1. Engelhardt, 1. 99. Cross et al., 1. 99. Laird et al., 1. 99. Santos et al., 1. At therapeutic doses of 7. Stichtenoth et al., 1. De Meijer et al., 1. Panara et al., 1. Tegeder et al., 1. This demonstrated the low inhibitory activity against COX- 1 of meloxicam in vivo. A total of 2. 0,0. Degner et al., 2. These trials showed that meloxicam was as effective as diclofenac or piroxicam (Hosie et al., 1. Linden et al., 1. Goei et al., 1. 99. Lund et al., 1. 99. OA. Similarly, trials in patients with RA demonstrated that in doses of 7. NSAIDs in established doses for periods of up to 1. Huskisson et al., 1. Wojtulewski et al., 1. Lemmel et al., 1. Two large- scale, prospective, multicenter trials, the Meloxicam Large- Scale International Study Safety Assessment (MELISSA) and the Safety and Efficacy Large- Scale Evaluation of COX- Inhibiting Therapies (SELECT) compared 7. MELISSA) or 2. 0 mg/day piroxicam (SELECT) for 2. OA patients. In the MELISSA (Hawkey et al., 1. GI adverse events were recorded for meloxicam- treated patients (1. P < 0. 0. 01). There were 5 patient days of hospitalization in patients on meloxicam compared with 1. In the SELECT trial (Dequeker et al., 1. GI adverse events was lower in the meloxicam than in the piroxicam group (1. P < 0. 0. 01).
