  • Emerging Drug List PARECOXIB SODIUM
    Emerging Drug List PARECOXIB SODIUM NO. 10 MAY 2001 Generic (Trade Name): Parecoxib sodium Manufacturer: Pharmacia & Upjohn Inc. Indication: For peri-operative pain relief Current Regulatory Parecoxib is currently under review at Health Canada and the Food and Drug Status: Administration in the U.S. They are expecting approval in the fourth quarter of 2001. It is not marketed in any country at this time Description: Parecoxib is the first parenteral cyclooxygenase-2 (COX-2) selective inhibitor to be developed. It is a water-soluble prodrug that is rapidly hydrolyzed to valdecoxib (the active COX-2 inhibitor). Valdecoxib's affinity for COX-2 versus COX-1 is 90 times greater than celecoxib and 34,000 times greater than ketorolac. Once injected, peak concentrations of valdecoxib are attained in 10 to 20 minutes. Valdecoxib has a half-life of eight to 10 hours. Current Treatment: Currently, the only other nonsteroidal anti-inflammatory agent that is available as an injection is ketorolac. Ketorolac is used in some centres for peri-operative pain management, however opioids are the main class of agents used for this indication. Ketorolac has been associated with a relatively high incidence of gastrointestinal (GI) side effects, including severe cases of hemorrhage. Cost: There is no information available on the cost of parecoxib. Evidence: Parecoxib has been compared to ketorolac and morphine in clinical trials. Parecoxib at a dose of 20 and 40 mg/day IV, were compared to ketorolac, 30 mg/day IV and morphine, 4 mg/day or placebo in 202 women undergoing hysterectomy. Both doses of parecoxib were comparable to ketorolac for relieving postoperative pain.

  • Safety of Etoricoxib in Patients with Reactions to Nsaids
    ORIGINAL ARTICLE Safety of Etoricoxib in Patients With Reactions to NSAIDs O Quercia, F Emiliani, FG Foschi, GF Stefanini Allergology High Specialty Unit, General Medicine, Faenza Hospital, AUSL Ravenna, Italy ■ Abstract Background: Adverse reactions to nonsteroidal anti-infl ammatory drugs (NSAIDs) are a frequently reported problem due to the fact that these molecules are often used for control of pain and infl ammation. Although the use of selective inhibitors of cyclooxygenase (COX) 2 helps to prevent some of these adverse reactions, they can have cardiac side effects when taken for prolonged periods. Here we report the safety and tolerability of etoricoxib, a selective COX-2 inhibitor with fewer cardiovascular effects, in patients with adverse reactions to NSAIDs. Patients and methods: We performed placebo-controlled oral challenge with etoricoxib in 65 patients with previous adverse reactions to NSAIDs: 13 to salicylates, 18 to arylpropionic acids, 10 to arylacetic acid, 12 to oxicam and derivates, 8 to pyrazolones, and 4 to acetaminophen (paracetamol). The reported symptoms were urticaria or angioedema in 69%, rhinitis in 3%, and 1 case of anaphylactic shock (1.5%). The challenge was done using the placebo on the fi rst day, half dosage of etoricoxib (45 mg) on the second day, and the therapeutic dose of 90 mg on the third day. The challenge was done in the outpatient department of the hospital and the subjects were monitored for a further 4 to 6 hours after challenge. Results: Oral challenge with etoricoxib was well tolerated in 97% of the patients. Only 2 systemic reactions were reported during the challenge test.

  • Clinical Pharmacology of Novel Selective COX-2 Inhibitors
    Current Pharmaceutical Design, 2004, 10, 0000-0000 1 Clinical Pharmacology of Novel Selective COX-2 Inhibitors S. Tacconelli, M. L. Capone and P. Patrignani* Department of Medicine and Center of Excellence on Aging, “G. d’Annunzio” University, Chieti, Italy Abstract: Novel coxibs (i.e. etoricoxib, valdecoxib, parecoxib and lumiracoxib) with enhanced biochemical cyclooxygenase (COX)-2 selectivity over that of rofecoxib and celecoxib have been recently developed. They have the potential advantage to spare COX-1 activity, thus reducing gastrointestinal toxicity, even when administered at high doses to improve efficacy. They are characterized by different pharmacodynamic and pharmacokinetics features. The higher biochemical selectivity of valdecoxib than celecoxib, evidenced in vitro, may be clinically relevant leading to an improved gastrointestinal safety. Interestingly, parecoxib, a pro-drug of valdecoxib, is the only injectable coxib. Etoricoxib shows only a slightly improved COX-2 selectivity than rofecoxib, a highly selective COX-2 inhibitor that has been reported to halve the incidence of serious gastrointestinal toxicity compared to nonselective nonsteroidal antiinflammatory drugs (NSAIDs). Lumiracoxib, the most selective COX-2 inhibitor in vitro, is the only acidic coxib. The hypothesis that this chemical property may lead to an increased and persistent drug accumulation in inflammatory sites and consequently to an improved clinical efficacy, however, remains to be verified. Several randomized clinical studies suggest that the novel coxibs have comparable efficacy to nonselective NSAIDs in the treatment of osteoarthritis, rheumatoid arthritis and acute pain, but they share similar renal side-effects. The apparent dose-dependence of renal toxicity may limit the use of higher doses of the novel coxibs for improved efficacy.

  • Dynastat, INN-Parecoxib
    ANNEX I SUMMARY OF PRODUCT CHARACTERISTICS 1 1. NAME OF THE MEDICINAL PRODUCT Dynastat 40 mg powder for solution for injection 2. QUALITATIVE AND QUANTITATIVE COMPOSITION Each vial contains 40 mg parecoxib (as 42.36 mg parecoxib sodium). After reconstitution, the concentration of parecoxib is 20 mg/ml. Each 2 ml of reconstituted powder contains 40 mg of parecoxib. Excipient with known effect This medicinal product contains less than 1 mmol sodium (23 mg) per dose. When reconstituted in sodium chloride 9 mg/ml (0.9%) solution, Dynastat contains approximately 0.44 mmol of sodium per vial. For the full list of excipients, see section 6.1. 3. PHARMACEUTICAL FORM Powder for solution for injection (powder for injection). White to off-white powder. 4. CLINICAL PARTICULARS 4.1 Therapeutic indications For the short-term treatment of postoperative pain in adults. The decision to prescribe a selective cyclooxygenase-2 (COX-2) inhibitor should be based on an assessment of the individual patient's overall risks (see sections 4.3 and 4.4). 4.2 Posology and method of administration Posology The recommended dose is 40 mg administered intravenously (IV) or intramuscularly (IM), followed every 6 to 12 hours by 20 mg or 40 mg as required, not to exceed 80 mg/day. As the cardiovascular risk of COX-2 specific inhibitors may increase with dose and duration of exposure, the shortest duration possible and the lowest effective daily dose should be used. There is limited clinical experience with Dynastat treatment beyond three days (see section 5.1). Concomitant use with opioid analgesics Opioid analgesics can be used concurrently with parecoxib, dosing as described in the paragraph above.

    European Medicines Agency Press office London, 15 December 2004 EMEA/204802/2004 EMEA PUBLIC STATEMENT ON VALDECOXIB (Bextra/Valdyn) and PARECOXIB SODIUM (Dynastat/Rayzon) CARDIOVASCULAR RISKS IN CORONARY ARTERY BYPASS GRAFT (CABG) SURGERY AND SERIOUS ADVERSE SKIN REACTIONS The European Medicines Agency (EMEA) and its Scientific Committee for human medicines have been made aware of new safety information on cardiovascular and serious skin adverse events in relation to the use of valdecoxib and parecoxib sodium. Cardiovascular safety Two clinical studies were conducted to evaluate the safety of valdecoxib and parecoxib sodium, in patients following CABG surgery and another study in patients following general surgery. The first CABG study evaluated the safety of parecoxib sodium/valdecoxib 40 mg BID given for up to 14 days in 462 patients (311 on parecoxib sodium/valdecoxib and 151 on placebo). The second CABG surgery study evaluated parecoxib sodium (40mg then 20mg bid) /valdecoxib 20 mg bid or placebo/valdecoxib 20 mg bid or placebo/placebo for up to 10 days in 1671 patients (544 receiving parecoxib/valdecoxib, 544 placebo/valdecoxib and 548 placebo/placebo). Both CABG studies showed a higher rate of serious cardiovascular thromboembolic events (e.g. myocardial infarction, cerebrovascular accident) in the parecoxib sodium/valdecoxib treatment arm compared to the group of patients receiving placebo. This was not observed in a general surgery setting. Serious Skin Reactions The EMEA has received new post-marketing reports of serious skin reactions, some with fatal outcome, including erythema multiforme, exfoliative dermatitis, Stevens-Johnson syndrome and toxic epidermal necrolysis in patients receiving valdecoxib. Erythema multiforme has been reported in association with the use of parecoxib sodium.
