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. -
What Are the Acute Treatments for Migraine and How Are They Used?
2. Acute Treatment CQ II-2-1 What are the acute treatments for migraine and how are they used? Recommendation The mainstay of acute treatment for migraine is pharmacotherapy. The drugs used include (1) acetaminophen, (2) non-steroidal anti-inflammatory drugs (NSAIDs), (3) ergotamines, (4) triptans and (5) antiemetics. Stratified treatment according to the severity of migraine is recommended: use NSAIDs such as aspirin and naproxen for mild to moderate headache, and use triptans for moderate to severe headache, or even mild to moderate headache when NSAIDs were ineffective in the past. It is necessary to give guidance and cautions to patients having acute attacks, and explain the methods of using medications (timing, dose, frequency of use) and medication use during pregnancy and breast-feeding. Grade A Background and Objective The objective of acute treatment is to resolve the migraine attack completely and rapidly and restore the patient’s normal functions. An ideal treatment should have the following characteristics: (1) resolves pain and associated symptoms rapidly; (2) is consistently effective; (3) no recurrence; (4) no need for additional use of medication; (5) no adverse effects; (6) can be administered by the patients themselves; and (7) low cost. Literature was searched to identify acute treatments that satisfy the above conditions. Comments and Evidence The acute treatment drugs for migraine generally include (1) acetaminophens, (2) non-steroidal anti-inflammatory drugs (NSAIDs), (3) ergotamines, (4) triptans, and (5) antiemetics. For severe migraines including status migrainosus and migraine attacks refractory to treatment, (6) anesthetics, and (7) corticosteroids (dexamethasone) are used (Tables 1 and 2).1)-9) There are two approaches to the selection and sequencing of these medications: “step care” and “stratified care”. -

Abstract A series of fenamate pyridyl or quinolinyl analogues of 1,3,4-oxadiazol-2-ones 5a-d and 6a-r, and 1,3,4-oxadiazole-2-thiones 5e-g and 6s-v, respectively, have been synthesized and evaluated for their analgesic (hot-plate) , antiinflammatory (carrageenin induced rat's paw edema) and ulcerogenic effects as well as plasma prostaglandin E2 (PGE2) level. The highest analgesic activity was achieved with compound 5a (0.5 ,0.6 ,0.7 mrnolkg b.wt.) in respect with mefenamic acid (0.4 mmollkg b.wt.). Compounds 6h, 61 and 5g showed 93, 88 and 84% inhibition, respectively on the carrageenan-induced rat's paw edema at dose level of O.lrnrnol/kg b.wt, compared with 58% inhibition of mefenamic acid (0.2mmoll kg b.wt.). Moreover, the highest inhibitory activity on plasma PGE2 level was displayed also with 6h, 61 and 5g (71, 70,68.5% respectively, 0.lmmolkg b.wt.) compared with indomethacin (60%, 0.01 mmolkg b.wt.) as a reference drug. -
Studies in Laboratory Animals to Assess the Safety of Anti-Inflammatory Agents in Acute Porphyria
Ann Rheum Dis: first published as 10.1136/ard.46.7.540 on 1 July 1987. Downloaded from Annals of the Rheumatic Diseases, 1987; 46, 540-542 Studies in laboratory animals to assess the safety of anti-inflammatory agents in acute porphyria KENNETH E L McCOLL, GEORGE G THOMPSON, AND MICHAEL R MOORE From the University Department of Medicine, Western Infirmary, Glasgow SUMMARY The safety of various anti-inflammatory drugs in acute porphyria was assessed by examining their effect on rat hepatic haem synthesis. Azapropazone, chloroquine, and gold increased 6-aminolaevulinic acid (ALA) synthase activity, indicating that they are liable to precipitate porphyric crises. Aspirin, ibuprofen, indomethacin, ketoprofen, flurbiprofen, phenylbutazone, naproxen, prednisolone, and penicillamine did not increase ALA synthase activity and should be safe in porphyria. Though these animal studies can be used as a guide to prescribing in patients with acute porphyria, some caution is still required as species may vary in their response to inducing agents. Key words: chloroquine, azapropazone, gold, b-aminolaevulinic acid synthase. copyright.

Castañeda-Hernández1 and A.E. Chávez-Piña1 1Departamento de Farmacología, Centro de Investigación y de Estudios Avanzados del Instituto Politécnico Nacional, México, D.F., México. 2Área Académica de Medicina del Instituto de Ciencias de la Salud, Universidad Autónoma del Estado de Hidalgo, Pachuca, Hidalgo, México SUMMARY Indomethacin is a nonsteroidal anti-inflammatory drug (NSAID) used for the treatment of acute gout and inflammation. However, its use is limited due to side effects. Acemetacin is a prodrug of indomethacin that exhibits better gastric tolerability in preclinical and clinical tri- als. The aim of this study was to examine if the systemic administration of acemetacin involved the sequential participation of nitric oxide (NO) or K+ channel pathways to confer its antinociceptive effect, as compared to indomethacin. The antinociceptive effect of both drugs was studied with the formalin test. Equimolar doses of acemetacin or indomethacin were administered orally. The intraplantar administra- tion of either L-NAME, glibenclamide, apamin or charybdotoxin plus indomethacin or acemetacin was studied using the formalin test and the anti-inflammatory and antihyperalgesic effects were measured. The antinociceptive effect of acemetacin or indomethacin was not sig- nificantly different when pretreatment with L-NAME, glibenclamide, apamin or charybdotoxin was done. The antihyperalgesic and anti- inflammatory effects were also similar for both indomethacin and acemetacin. -
Binding of Nonsteroidal Anti-Inflammatory Drugs to DPPC: Structure and Thermodynamic Aspects

In Final Form: January 8, 2008 The effect of nonsteroidal anti-inflammatory drugs (NSAIDs) on the phase transition and phase properties of 1,2-dipalmitoylphosphatidylcholine (DPPC) has been investigated in both 2D (monolayers at the air/water interface) and 3D (multilayers in lipid/water dispersions) model systems. The 2D membrane models have been characterized by means of pressure-area isotherms and grazing incidence X-ray diffraction (GIXD) measurements. Differential scanning calorimetry (DSC) and simultaneous small- and wide-angle X-ray diffraction have been applied to lipid aqueous dispersions. All NSAIDs studied altered the main transition temperature of the gel to liquid-crystalline phase transition, with the arylacetic acid derivatives (acemetacin and indomethacin) showing the largest effects. A comparison of the results reveals distinct structural features of the membrane models after interaction with the NSAID. All drugs induced perturbations in the lipid liquid-crystalline phase, suggesting a major change in the hydration behavior of DPPC. Again, the largest effects on the structural parameters are found for the arylacetic acid derivatives. The results obtained in the different model systems give indications of the role of the membrane/NSAID interactions that might also be important for NSAID gastric injury. -
