Ascorbic Acid Ameliorates Cardiac and Hepatic Toxicity Induced by Azithromycin-Etoricoxib Drug Interaction. Curr Issues Mol Biol 2022; 44:2529-2541. [PMID: 35735613 PMCID: PMC9222074 DOI: 10.3390/cimb44060172] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2022] [Revised: 05/20/2022] [Accepted: 05/23/2022] [Indexed: 11/20/2022] Open
Abstract
The complexity of prescribing safe and effective drug therapy is still challenging. Due to the increased number of medications taken by patients, the potential for drug-drug interactions has clinically important consequences. This study focuses on the potential drug-drug interaction between azithromycin and etoricoxib and the possibility of counteracting this adverse reaction by giving ascorbic acid intraperitoneally to male albino rats. Sixty adult male albino rats weighing 150–180 g were used. The rats were allocated into six equal groups. One group was a control, and the others were given azithromycin, etoricoxib, either alone or combination, with one group treated with ascorbic acid and the last group treated with the drug combination and ascorbic acid. Blood samples were collected for measuring AST, ALT, LDH, CK-MB, and troponin alongside antioxidant enzymes and histopathological examination for both liver and heart tissue. The results showed both hepatic and cardiac damage in azithromycin and etoricoxib groups represented by increasing levels of heaptoc enzymes (ALT, AST, LDH, CK-MB, and troponin) with declining antioxidant enzymes and elevation of malondialdehyde and the appearance of hepatic and cardiac toxicities. Upon administration, ascorbic acid ameliorated all the mentioned biochemical parameters. In conclusion, ascorbic acid has great antioxidant capacities and hepatic and cardiac ameliorative effects and can alleviate drug interaction toxicity.

Abstract
Korean guidelines for nonsteroidal anti-inflammatory drug (NSAID)-induced peptic ulcer were previously developed in 2009 with the collaboration of the Korean College of Helicobacter and Upper Gastrointestinal Research and Korean Society of Gastroenterology. However, the previous guidelines were based mainly upon a review of the relevant literature and expert opinion. Therefore, the guidelines need to be revised. We organized a guideline Development Committee for drug-related peptic ulcer under the auspices of the Korean College of Helicobacter and Upper Gastrointestinal Research in 2017 and developed nine statements, including four for NSAIDs, three for aspirin and other antiplatelet agents, and two for anticoagulants through a de novo process founded on evidence-based medicine that included a literature search and a meta-analysis, A consensus was reached through the application of the modified Delphi method. The primary target of these guidelines is adult patients undergoing long-term treatment with NSAIDs, aspirin or other antiplatelet agents and anticoagulants. The revised guidelines reflect the expert consensus and is intended to assist clinicians in the management and prevention of drug-induced peptic ulcer and associated conditions.

Abstract
The Korean guidelines for nonsteroidal anti-inflammatory drug (NSAID)-induced peptic ulcers were previously developed under co-work with the Korean College of Helicobacter and Upper Gastrointestinal Research and Korean Society of Gastroenterology at 2009. On the other hand, the previous guidelines were based mainly on a literature review and expert opinions. Therefore, the guidelines need to be revised. In this study, a guideline development committee for drug-induced peptic ulcers was organized under the Korean College of Helicobacter and Upper Gastrointestinal Research in 2017. Nine statements were developed, including four for NSAID, three for aspirin and other antiplatelet agents, and two for anticoagulants through de novo processes based on evidence-based medicine, such as a literature search, meta-analysis, and the consensus was established using the modified Delphi method.

Efficacy of non-opioid analgesics to control postoperative pain: a network meta-analysis. BMC Anesthesiol 2020; 20:272. [PMID: 33109098 PMCID: PMC7592505 DOI: 10.1186/s12871-020-01147-y] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2020] [Accepted: 09/03/2020] [Indexed: 12/19/2022] Open
Abstract
Background The aim of this network meta-analysis (NMA) was to evaluate the safety and efficacy of intravenous (IV) Meloxicam 30 mg (MIV), an investigational non-steroidal anti-inflammatory drug (NSAID), and certain other IV non-opioid analgesics for moderate-severe acute postoperative pain. Methods We searched PubMed and CENTRAL for Randomized Controlled Trials (RCT) (years 2000–2019, adult human subjects) of IV non-opioid analgesics (IV NSAIDs or IV Acetaminophen) used to treat acute pain after abdominal, hysterectomy, bunionectomy or orthopedic procedures. A Bayesian NMA was conducted in R to rank treatments based on the standardized mean differences in sum of pain intensity difference from baseline up to 24 h postoperatively (sum of pain intensity difference: SPID 24). The probability and the cumulative probability of rank for each treatment were calculated, and the surface under the cumulative ranking curve (SUCRA) was applied to distinguish treatments on the basis of their outcomes such that higher SUCRA values indicate better outcomes. The study protocol was prospectively registered with by PROSPERO (CRD42019117360). Results Out of 2313 screened studies, 27 studies with 36 comparative observations were included, producing a treatment network that included the four non-opioid IV pain medications of interest (MIV, ketorolac, acetaminophen, and ibuprofen). MIV was associated with the largest SPID 24 for all procedure categories and comparators. The SUCRA ranking table indicated that MIV had the highest probability for the most effective treatment for abdominal (89.5%), bunionectomy (100%), and hysterectomy (99.8%). MIV was associated with significantly less MME utilization versus all comparators for abdominal procedures, hysterectomy, and versus acetaminophen in orthopedic procedures. Elsewhere MME utilization outcomes for MIV were largely equivalent or nominally better than other comparators. Odds of ORADEs were significantly higher for all comparators vs MIV for orthopedic (gastrointestinal) and hysterectomy (respiratory). Conclusions MIV 30 mg may provide better pain reduction with similar or better safety compared to other approved IV non-opioid analgesics. Caution is warranted in interpreting these results as all comparisons involving MIV were indirect.

Abstract
Intaking antithrombotic funds (ATA) and non-steroidal anti-inflammatory drugs (NSAIDs) is one of the most frequent causes of pathology in gastrointestinal (GI) tract.The purpose of the study: comparison of pathological changes of the mucous membrane in the upper GI tract, that occur against the background of ATA and NSAIDs admission.Material and methods. Endoscopic data of two groups of patients taking ATA and NSAIDS have been compared. The first group of 448 patients from the 10th Gastrointestinal Department in N.N. Burdenko Main Military Clinical Hospital was on record from 2013 to 2017. The patients had erosive ulcerous changes of gastrointestinal mucosa, occurred against the background of the ATA admission. The second group comprised 6431 patients with rheumatic diseases. They were hospitalized in the clinic of V.A. Nasonova Research Institute of Rheumatology in the period from 2007 to 2016 and took NSAIDs regularly.Results. Duodenal and gastric ulcer changes in gastric mucosa and duodenal ulcers were identified in 168 (37.5 %) patients taking ATA and in 1691 (26.3 %) patient treated with NSAIDS. Structure of pathology varied. So, against the background of ATA and NSAIDS admission, the number of acute gastric ulceration amounted to 6.5 % and 15.5 % (p < 0.001); acute ulcers duodenal was 2.9 % and 4.9 %; combined ulcerative lesions of gastric and duodenal was 2.9 % and 2.0 %; multiple erosions of gastroduodenal mucosa were 52.4 % and 15.7 % (p < 0.001); single erosion was 35. 1% and 61.6 %. The factor of ulcer history and age ≥ 65 years old increased significantly the risk of duodenal and gastric ulcer changes in patients taking ATA and NSAIDs: OR 5.182 (95% CI 2.701–9.942) and 3.24 (95% CI 2.19–5.34), 4.537 (95% CI 2.036–10.11) and 2.016 (95% CI 1.230–2.917) respectively. Intaking of proton pump inhibitor (PPI) reduced significantly the risk of complications for both ATA and NSAIDs: OR 0.329 (95% CI 0.199–0.546) and 0.317 (95% CI 0.210–0.428) respectively.Conclusion. The structure of pathology of mucous in the upper gastrointestinal tract that arose against the backdrop of ATA and NSAIDs admission is different. The first is characterized by a multiple erosion, while the second one has single acute distal gastric ulcers. The ulcerative history and advanced age of patients increase significantly the risk of complications concerning the gastroduodenal mucosa when using ATA and NSAIDs. PPI is the effective means of preventing this pathology.

Bioactive factors for cartilage repair and regeneration: Improving delivery, retention, and activity. Acta Biomater 2019; 93:222-238. [PMID: 30711660 PMCID: PMC6616001 DOI: 10.1016/j.actbio.2019.01.061] [Citation(s) in RCA: 66] [Impact Index Per Article: 13.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2018] [Revised: 01/25/2019] [Accepted: 01/29/2019] [Indexed: 12/29/2022]
Abstract
Articular cartilage is a remarkable tissue whose sophisticated composition and architecture allow it to withstand complex stresses within the joint. Once injured, cartilage lacks the capacity to self-repair, and injuries often progress to joint wide osteoarthritis (OA) resulting in debilitating pain and loss of mobility. Current palliative and surgical management provides short-term symptom relief, but almost always progresses to further deterioration in the long term. A number of bioactive factors, including drugs, corticosteroids, and growth factors, have been utilized in the clinic, in clinical trials, or in emerging research studies to alleviate the inflamed joint environment or to promote new cartilage tissue formation. However, these therapies remain limited in their duration and effectiveness. For this reason, current efforts are focused on improving the localization, retention, and activity of these bioactive factors. The purpose of this review is to highlight recent advances in drug delivery for the treatment of damaged or degenerated cartilage. First, we summarize material and modification techniques to improve the delivery of these factors to damaged tissue and enhance their retention and action within the joint environment. Second, we discuss recent studies using novel methods to promote new cartilage formation via biofactor delivery, that have potential for improving future long-term clinical outcomes. Lastly, we review the emerging field of orthobiologics, using delivered and endogenous cells as drug-delivering "factories" to preserve and restore joint health. Enhancing drug delivery systems can improve both restorative and regenerative treatments for damaged cartilage. STATEMENT OF SIGNIFICANCE: Articular cartilage is a remarkable and sophisticated tissue that tolerates complex stresses within the joint. When injured, cartilage cannot self-repair, and these injuries often progress to joint-wide osteoarthritis, causing patients debilitating pain and loss of mobility. Current palliative and surgical treatments only provide short-term symptomatic relief and are limited with regards to efficiency and efficacy. Bioactive factors, such as drugs and growth factors, can improve outcomes to either stabilize the degenerated environment or regenerate replacement tissue. This review highlights recent advances and novel techniques to enhance the delivery, localization, retention, and activity of these factors, providing an overview of the cartilage drug delivery field that can guide future research in restorative and regenerative treatments for damaged cartilage.

Abstract
INTRODUCTION The efficacy of etoricoxib on pain control for laparoscopic cholecystectomy remains controversial. We conduct a systematic review and meta-analysis to explore the impact of etoricoxib on pain intensity after laparoscopic cholecystectomy. MATERIALS AND METHODS We searched PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through September 2018 for randomized controlled trials assessing the effect of etoricoxib versus placebo on pain management after laparoscopic cholecystectomy. This meta-analysis was performed using the random-effect model. RESULTS Four randomized controlled trials involving 351 patients are included in the meta-analysis. Overall, compared with control group for laparoscopic cholecystectomy, etoricoxib has no important impact on pain scores within 4 hours [mean difference (MD)=-1.48; 95% confidence interval (CI)=-3.54 to 0.58; P=0.16] and 8 hours (MD=-0.65; 95% CI=-1.43 to 0.12; P=0.10), but can significantly decrease pain intensity within 12 hours (MD=-1.16; 95% CI=-1.93 to -0.38; P=0.003) and 24 hours (MD=-1.10; 95% CI=-1.98 to -0.22; P=0.01), as well as postoperative analgesic consumption (standard MD=-1.21; 95% CI=-2.19 to -0.23; P=0.02), with no increase in nausea and vomiting (risk ratio=0.68; 95% CI=0.42-1.10; P=0.11), and headache (risk ratio=0.96; 95% CI=0.44-2.09; P=0.92). CONCLUSIONS Etoricoxib can substantially reduce pain intensity in patients with laparoscopic cholecystectomy.

Abstract
Etoricoxib is a selective cyclooxygenase-2 inhibitor, with a lower risk of gastrointestinal toxicity compared to traditional nonsteroidal anti-inflammatory drugs (NSAIDs). We evaluated the effectiveness and tolerability of etoricoxib in extremely elderly patients with chronic pain due to osteoarthritis (OA). A prospective, single-center, single-arm study was conducted, enrolling 19 extremely elderly men with OA (mean age 85.9, range 79-96 years), who responded inadequately to NSAIDs or other analgesics. Patients were switched to etoricoxib, 60 mg once daily for 4 weeks, without prior medication washout. Data were recorded before and after etoricoxib treatment. The primary endpoint was improvement in pain, assessed using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) after the 4-week treatment. Other endpoints included the Brief Pain Inventory Short Form (BPI-SF), Treatment Satisfaction Questionnaire for Medication (TSQM), Short Form 36 (SF36), and European Quality of Life-5 Dimensions (EQ-5D). Safety and tolerability were assessed by collecting adverse events data. Pain and disability scores measured by WOMAC index were lower after treatment (pain, p ≤ 0.001; disability, p = 0.020). BPI-SF showed a significant improvement in joint function when walking and performing normal work (walking, p = 0.021; normal work, p = 0.030). SF36 scores improved for 7 out of 11 items after etoricoxib treatment (#1, p = 0.032; #4, p = 0.026; #5, p = 0.017; #6, p = 0.008; #7, p = 0.009; #8, p = 0.013; and #10, p = 0.038). EQ-5D showed a significant improvement in visual analogue scale scores (p = 0.036). TSQM results demonstrated a higher patient perception of overall satisfaction. No adverse events were reported. Pain relief, joint function, quality of life, and treatment satisfaction improved significantly in elderly patients with OA after etoricoxib administration.

Abstract
Objective To ascertain if etoricoxib increases the risk of gastrointestinal adverse events (GAEs) compared with placebo, diclofenac, and naproxen in the treatment of patients with osteoarthritis (OA) or rheumatoid arthritis (RA). Methods Studies were searched in MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials from inception to August 2017. Randomized Clinical Trials (RCTs) that compared etoricoxib with placebo and other active drug for patients with OA or RA and reported data on gastrointestinal safety (which is of interest to patients and clinicians) were included. The follow-up time window for GAEs was defined as within 28 days subsequent to the last dose of study medication. A meta-analysis was conducted using a fixed-effect model. Risk ratios (RRs) and 95% confidence intervals (CIs) were measured. Results We found nine randomized clinical trials (RCTs) that included information on gastrointestinal safety during follow-up time. Among them, five RCTs compared etoricoxib with placebo, four RCTs compared etoricoxib with diclofenac, and three RCTs compared etoricoxib with naproxen. Etoricoxib did not increase the risk of GAEs compared with placebo. Compared with diclofenac and naproxen, etoricoxib reduced the GAE risk (RR, 0.67; 95% CI, 0.59–0.76; p < 0.00001; 0.59; 0.48–0.72; < 0.00001) during follow-up time. Conclusions In patients with OA or RA, etoricoxib did not increase the GAE risk compared with placebo, but reduced the GAE risk effectively compared with diclofenac and naproxen during follow-up time.

Abstract
Pain is one of the most disabling symptoms of rheumatoid diseases. Patients with pain secondary to osteoarthritis (OA), rheumatoid arthritis (RA), ankylosing spondylitis (AS) or gout require effective analgesic treatment, and the physician’s task is to select a drug that is best suited for an individual patient. The choice of pharmacotherapy should be based both on drug potency and clinical efficacy, and its safety profile, particularly in the elderly population, as the number of comorbidities (and hence the risk of treatment complications and drug interactions) rises with age. In cases involving a high risk of gastrointestinal complications or concerns about hepatotoxicity, with a low cardiovascular risk, the first-line nonsteroidal anti-inflammatory drugs to consider should be coxibs including etoricoxib.

Abstract
BACKGROUND It is uncertain whether concurrent use of low-dose aspirin removes the gastrointestinal benefit displayed by COX-2 selective inhibitors (coxibs) when compared to traditional nonsteroidal anti-inflammatory drugs (NSAIDs). AIM To evaluate the gastrointestinal risks associated with coxibs and traditional NSAIDs and the interaction with concurrent use of low-dose aspirin. METHODS We searched MEDLINE, EMBASE and the Cochrane Library through April 2016 to identify randomised trials comparing the gastrointestinal risk between coxibs and traditional NSAIDs in patients taking or not taking low-dose aspirin. Results were combined using random effects meta-analysis. Subgroup analyses by concurrent use of aspirin were undertaken. RESULTS Eleven trials (84 150 participants) were included. The overall relative risk (RR) of coxibs vs. traditional NSAIDs for complicated gastrointestinal events was 0.54 (95% CI, confidence interval 0.32-0.92), with a significant subgroup difference (P = 0.04) according to concurrent use of aspirin (used: RR = 0.96, 95% CI 0.66-1.24; not used: RR = 0.33, 95% CI 0.14-0.83). The overall RR for clinical gastrointestinal events was 0.59 (95% CI 0.47-0.75), with a significant subgroup difference according to aspirin usage (P = 0.008; used: RR = 0.77, 95% CI 0.62-0.95; not used: RR = 0.50, 95% CI 0.39-0.64). Overall coxibs were associated with significantly lower risk of symptomatic ulcers (RR = 0.60, 95% CI 0.50-0.72) and endoscopic ulcers (RR = 0.29, 95% CI 0.16-0.53) than traditional NSAIDs; a significant subgroup difference was shown for endoscopic ulcers (P = 0.05) but not for symptomatic ulcers (P = 0.27). CONCLUSION Concomitant use of low-dose aspirin reduces but does not completely eliminate the gastrointestinal benefit of coxibs over traditional NSAIDs.

Safety of Etoricoxib, Celecoxib, and Nonselective Nonsteroidal Antiinflammatory Drugs in Ankylosing Spondylitis and Other Spondyloarthritis Patients: A Swedish National Population-Based Cohort Study. Arthritis Care Res (Hoboken) 2015; 67:1137-49.

Abstract
OBJECTIVE Safety data regarding the use of etoricoxib and other nonsteroidal antiinflammatory drugs (NSAIDs) in ankylosing spondylitis (AS) and other spondyloarthritis (SpA) patients are rather limited. Our objective was to estimate and compare rates of gastrointestinal, renovascular, and cardiovascular adverse events in patients exposed to etoricoxib, celecoxib, or nonselective NSAIDs or totally unexposed to NSAIDs. METHODS We performed a national register-based cohort study on patients with AS or SpA (n = 21,872) identified in the Swedish national patient register from 1987-2009. Treatment exposure was assessed time dependently based on the prescription drug register from 2006-2009, adjusting for sociodemographics and comorbidities derived from national population-based registers. RESULTS Exposure to etoricoxib, celecoxib, and nonselective NSAIDs was 7.6%, 3.9%, and 71.2%, respectively. No major risk differences for serious cardiovascular, gastrointestinal, or renal adverse events were seen among the 3 exposure groups. Patients unexposed to NSAIDs had more baseline comorbidities and an increased relative risk for congestive heart failure events during the study period (2.0, 95% confidence interval [95% CI] 1.3-3.2). The relative risk for atherosclerotic events was nonsignificant when compared to the nonselective NSAID group (1.0, 95% CI 0.7-1.5), while the relative risk for gastrointestinal events was lower for unexposed patients (0.5, 95% CI 0.4-0.7). CONCLUSION Overall, serious adverse events related to nonselective NSAIDs, etoricoxib, and celecoxib were similar and in the range of what would be expected in a group of SpA patients. Patients unexposed to NSAIDs had considerably more baseline comorbidities and increased risk for congestive heart failure, reflecting a selection of patients being prescribed NSAIDs in clinical practice.

Abstract
Currently 2 difference classes of cyclooxygenase (COX)-2 inhibitors, coxibs and relatively selective COX-2 inhibitors, are available for patients requiring nonsteroidal anti-inflammatory drug (NSAID) therapy; their gastroprotective effect is hardly directly compared. The aim of this study was to compare the gastroprotective effect of relatively selective COX-2 inhibitors with coxibs. MEDLINE, EMBASE, and the Cochrane Library (from their inception to March 2015) were searched for potential eligible studies. We included randomized controlled trials comparing coxibs (celecoxib, etoricoxib, parecoxib, and lumiracoxib), relatively selective COX-2 inhibitors (nabumetone, meloxicam, and etodolac), and nonselective NSAIDs with a study duration ≥ 4 weeks. Comparative effectiveness and safety data were pooled by Bayesian network meta-analysis. The primary outcomes were ulcer complications and symptomatic ulcer. Summary effect-size was calculated as risk ratio (RR), together with the 95% confidence interval (CI). This study included 36 trials with a total of 112,351 participants. Network meta-analyses indicated no significant difference between relatively selective COX-2 inhibitors and coxibs regarding ulcer complications (RR, 1.38; 95% CI, 0.47-3.27), symptomatic ulcer (RR, 1.02; 95% CI, 0.09-3.92), and endoscopic ulcer (RR, 1.18; 95% CI, 0.37-2.96). Network meta-analyses adjusting potential influential factors (age, sex, previous ulcer disease, and follow-up time), and sensitivity analyses did not reveal any major change to the main results. Network meta-analyses suggested that relatively selective COX-2 inhibitors and coxibs were associated with comparable incidences of total adverse events (AEs) (RR, 1.09; 95% CI, 0.93-1.31), gastrointestinal AEs (RR, 1.04; 95% CI, 0.87-1.25), total withdrawals (RR, 1.00; 95% CI, 0.74-1.33), and gastrointestinal AE-related withdrawals (RR, 1.02; 95% CI, 0.57-1.74). Relatively selective COX-2 inhibitors appear to be associated with similar gastroprotective effect and tolerability as coxibs. Owing to the indirectness of the comparisons, future research is required to confirm the study conclusion.

Abstract
AIM To study the clinical and laboratory efficiency and safety of different etoricoxib (ET) regimens in patients with axial spondyloarthritis (axSpA), including ankylosing spondylitis. SUBJECTS AND METHODS Forty patients with high axSpA activity (Bath Ankylosing Disease Activity Index (BASDAI 4) were examined and randomized to 2 groups: 1) 30 patients who received ET 90 mg continuously every day; 2) 10 patients who took the drug in the same dose intermittently 1-3 times weekly. The activity of axSpA (BASDAI, Ankylosing Spondylitis Disease Activity Score (ASDAS), erythrocyte sedimentation rate (ESR), and high-sensitivity C-reactive protein (hs-CRP)) was evaluated at baseline, 2 and 12 weeks; adverse events were recorded at baseline, 2, 6, and 12 weeks. The number of patients who had achieved an ASAS40 response at 2 and 12 weeks were taken into consideration. RESULTS At 12 weeks, the continuous administration group displayed decreases in BASDAI from 8 to 4, in ASDAS from 3.8 to 2.6, and in hs-CRP levels from 9.5 to 3.9 mg/l; the intermittent administration group exhibited decreases in BASDAI from 7.6 to 6.0, in ASDAS from 3.5 to 3.1, and hs-CRP from 8.8 to 4.5 mg/l (p<0.05). At this time, an AS40 response was achieved by 22 (73.3%) and 2 (20%) patients in Groups 1 and 2, respectively (p<0.05 for all). No serious adverse events were recorded. CONCLUSION The efficacy of ET given in a daily dose of 90 mg was much higher than that of the drug used thrice or less weekly in the patients with axSpA.

Abstract
AIM To study a trend in active sacroiliitis (ASI) in patients with axial spondyloarthritis (axSpA) during different short-term regimens using etoricoxib (ET) 90 mg. SUBJECTS AND METHODS Forty patients with axSpA, including 30 with ankylosing spondyloarthritis), and ASI (sacroiliac joint (SIJ) osteitis as evidenced by magnetic resonance imaging) were examined and then randomized to 2 groups: 1) 20 patients who took ET 90 mg four days or more a week; 2) 20 patients who received ET 90 mg 3 days or less a week. Osteitis was measured in 4 quadrants of each SIJ (0-3 scores). Its main criterion was considered to be a decrease in total osteitis activity (TOA) 12 week later. RESULTS In all the patients (n = 40), TOA decreased from 6.5 (4; 9) to 2 (0; 5) scores (p < 0.0001). In Group 1 (n = 20), that reduced from 6.5 (4; 8.5) to 0 (0; 3) scores (p < 0.0001). In Group 2 (n = 20), that did from 6.5 (4; 10) to 4 (1; 8) scores (p = 0.49). At 12 weeks, in in Groups 1 and 2, the difference in final TOA achieved no statistical significance (p=0.056). In these groups, there were 19 (95%) and 14 (70%) treatment-responsive patients, respectively. CONCLUSION The intake of ET 90 mg for 12-weeks is associated with a reduction in the degree of ASI in patients with axSpA. The use of ET 4 times or more a week is more effective in diminishing osteitis than that of ET 3 days or less.

Abstract
The characteristic of a biomarker that makes it a useful surrogate is the ability to identify a high risk of clinically important benefits or harms occurring in the future. A number of definitions or descriptions of surrogate definition have been put forward. Most recently the Institute of Medicine of the National Academy of Sciences in the USA has put forward an evaluation scheme for biomarkers, looking at validation (assay performance), qualification (assessment of evidence), and utilisation (the context in which the surrogate is to be used). This paper examines the example of endoscopy as a surrogate marker of NSAID-induced mucosal damage using the Institute of Medicine criteria. The article finds extensive evidence that the detection of endoscopic ulcers is a valid marker. The process of qualification documents abundant evidence showing that endoscopic ulcers and serious upper gastrointestinal damage are influenced in the same direction and much the same magnitude by a variety of risk factors and interventions. Criticisms of validation and qualification for endoscopic ulcers have been examined, and dismissed. Context is the key, and in the context of serious NSAID-induced upper gastrointestinal harm, endoscopic ulcers represent a useful surrogate. Generalisability beyond this context is not considered.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs), such as non-selective NSAIDs (nsNSAIDs) or selective cyclooxygenase-2 (COX-2) inhibitors, are commonly prescribed for arthritic pain relief in patients with osteoarthritis (OA), rheumatoid arthritis (RA), or ankylosing spondylitis (AS). Treatment guidelines for chronic NSAID therapy include the consideration for gastroprotection for those at risk of gastric ulcers (GUs) associated with the chronic NSAID therapy. The United States Food and Drug Administration has approved naproxen/esomeprazole magnesium tablets for the relief of signs and symptoms of OA, RA, and AS, and to decrease the risk of developing GUs in patients at risk of developing NSAID-associated GUs. The European Medical Association has approved this therapy for the symptomatic treatment of OA, RA, and AS in patients who are at risk of developing NSAID-associated GUs and/or duodenal ulcers, for whom treatment with lower doses of naproxen or other NSAIDs is not considered sufficient. Naproxen/esomeprazole magnesium tablets have been compared with naproxen and celecoxib for these indications in head-to-head trials. This systematic literature review and network meta-analyses of data from randomized controlled trials was performed to compare naproxen/esomeprazole magnesium tablets with a number of additional relevant comparators. For this study, an original review examined MEDLINE®, Embase®, and the Cochrane Controlled Trials Register from database start to April 14, 2009. Using the same methodology, a review update was conducted to December 21, 2009. The systematic review and network analyses showed naproxen/esomeprazole magnesium tablets have an improved upper gastrointestinal tolerability profile (dyspepsia and gastric or gastroduodenal ulcers) over several active comparators (naproxen, ibuprofen, diclofenac, ketoprofen, etoricoxib, and fixed-dose diclofenac sodium plus misoprostol), and are equally effective as all active comparators in treating arthritic symptoms in patients with OA, RA, and AS. Naproxen/esomeprazole magnesium tablets are therefore a valuable option for treating arthritic symptoms in eligible patients with OA, RA, and AS.

Abstract
PURPOSE Heterotopic ossification is a common complication after total hip arthroplasty. Non-steroidal anti-inflammatory drugs (NSAIDs) are known to prevent heterotopic ossifications effectively, however gastrointestinal complaints are reported frequently. In this study, we investigated whether etoricoxib, a selective cyclo-oxygenase-2 (COX-2) inhibitor that produces fewer gastrointestinal side effects, is an effective alternative for the prevention of heterotopic ossification. METHODS We investigated the effectiveness of oral etoricoxib 90 mg for seven days in a prospective two-stage study design for phase-2 clinical trials in a small sample of patients (n = 42). A cemented primary total hip arthroplasty was implanted for osteoarthritis. Six months after surgery, heterotopic ossification was determined on anteroposterior pelvic radiographs using the Brooker classification. RESULTS No heterotopic ossification was found in 62 % of the patients that took etoricoxib; 31 % of the patients had Brooker grade 1 and 7 % Brooker grade 2 ossification. CONCLUSIONS Etoricoxib seems effective in preventing heterotopic ossification after total hip arthroplasty. This finding further supports the use of COX-2 inhibitors for the prevention of heterotopic ossification following total hip arthroplasty.

Abstract
INTRODUCTION Nonsteroidal anti-inflammatory drugs (NSAIDs) are first-line therapies in the management of patients with ankylosing spondylitis. This chronic inflammatory skeletal disorder, a subtype of spondyloarthritis, is characterized by inflammatory back pain and affects young adults causing important suffering and disability. Long-term use of conventional NSAIDs is associated with a risk of gastrointestinal complications. Etoricoxib is a specific cyclooxygenase 2 inhibitor with strong anti-inflammatory effects and a favorable pharmacokinetic profile for the management of inflammatory disorders. The drug has been associated with reduced severe gastrointestinal adverse events. However, the cardiovascular safety of cyclooxygenase 2 inhibitors has been debated. AREAS COVERED This review discusses etoricoxib in the treatment of ankylosing spondylitis. Literature searches were performed in PubMed, Web of Science, and the Cochrane library based on the terms "etoricoxib" and "ankylosing spondylitis" or "spondyloarthritis" as well as "safety" and "side-effects." EXPERT OPINION Etoricoxib is useful in the first-line management of ankylosing spondylitis patients. Its anti-inflammatory effects and relative protection against severe gastrointestinal side effects should be balanced with negative effects on the cardiovascular system and an overall subjective tolerance not better than that of conventional NSAIDs. Whether etoricoxib will also become a mainstay in the prevention of structural damage in ankylosing spondylitis is not yet clear.

Abstract
Cyclooxygenase (COX)-2-specific drugs such as rofecoxib and celecoxib and the newer agents, etoricoxib and valdecoxib, were developed to provide a safer alternative to traditional nonsteroidal antiinflammatory drugs (tNSAIDs). These drugs have been shown significantly to reduce endoscopically visualized gastrointestinal ulcers, and one of them, rofecoxib, has demonstrated a 50% reduction in clinically important gastrointestinal outcomes compared with a tNSAID. However, COX-derived prostaglandins also have complex interactions with the cardiovascular system. This article briefly reviews our current understanding of the interactions between prostaglandins and cardiovascular physiology, and addresses some of the concerns that recently have been raised regarding coxibs and the risk of cardiovascular events.

Abstract
To study the safety and efficacy of a new medical food (Theramine) in the treatment of low back pain, we performed a 28-day double-blind randomized controlled trial in 129 patients. Back pain was present for at least 6 weeks and was not mild. Patients were randomly assigned to receive medical food alone (n = 43), naproxen alone (250 mg/d, n = 42), or both medical food and naproxen (n = 44). All patients were assessed by using Roland-Morris Disability Questionnaire, Oswestry Low Back Pain Scale, Visual Analog Scale Evaluation and laboratory analysis performed at baseline and at 28 days for assessing the safety and impact on inflammatory markers, which included complete blood counts, C-Reactive protein (CRP), and liver function (alkaline phosphatase, aspartate transaminase, and alanine transaminase). At baseline, there were no statistically significant differences in low back pain when assessed by Roland-Morris function or Oswestry assessments nor were there differences in the blood indices of inflammation. At day 28, both the medical food group and combined therapy group (medical food with naproxen) were statistically significantly superior to the naproxen-alone group (P < 0.05). The medical food and naproxen group showed functional improvement when compared to the naproxen-alone group. The naproxen-alone group showed significant elevations in CRP, alanine transaminase, and aspartate transaminase when compared with the other groups. Medical food alone or with naproxen showed no significant change in liver function tests or CRP, with medical food potentially mitigating the effects seen with naproxen alone. The medical food (Theramine) appeared to be effective in relieving back pain without causing any significant side effects and may provide a safe alternative to presently available therapies.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) represent a diverse class of drugs and are among the most commonly used analgesics for arthritic pain worldwide, though long-term use is associated with a spectrum of adverse effects. The introduction of cyclooxygenase-2-selective NSAIDs early in the last decade offered an alternative to traditional NSAIDs with similar efficacy and improved gastrointestinal tolerability; however, emerging concerns about cardiovascular safety resulted in the withdrawal of two agents (rofecoxib and valdecoxib) in the mid-2000s and, subsequently, in an overall reduction in NSAID use. It is now understood that all NSAIDs are associated with some varying degree of gastrointestinal and cardiovascular risk. Guidelines still recommend their use, but little is known of how patients use these agents. While strategies and guidelines aimed at reducing NSAID-associated complications exist, there is a need for evidence-based algorithms combining cardiovascular and gastrointestinal factors that can be used to aid treatment decisions at an individual patient level.

Abstract
Despite major advances in diagnosis, prevention, and treatment, nonvariceal upper gastrointestinal bleeding still is a serious problem in clinical practice. Current evidence indicates that most peptic ulcer bleeding-linked deaths are not a direct sequela of the bleeding ulcer itself. Instead, mortality derives from multiorgan failure, cardiopulmonary conditions, or terminal malignancy, suggesting that improving further current treatments for the bleeding ulcer may have a limited impact on mortality unless supportive therapies are developed for the global management of these patients.

Abstract
Over the past two decades, transcatheter arterial embolization has become the first-line therapy for the management of upper gastrointestinal bleeding that is refractory to endoscopic hemostasis. Advances in catheter-based techniques and newer embolic agents, as well as recognition of the effectiveness of minimally invasive treatment options, have expanded the role of interventional radiology in the management of hemorrhage for a variety of indications, such as peptic ulcer bleeding, malignant disease, hemorrhagic Dieulafoy lesions and iatrogenic or trauma bleeding. Transcatheter interventions include the following: selective embolization of the feeding artery, sandwich coil occlusion of the gastroduodenal artery, blind or empiric embolization of the supposed bleeding vessel based on endoscopic findings and coil pseudoaneurysm or aneurysm embolization by three-dimensional sac packing with preservation of the parent artery. Transcatheter embolization is a fast, safe and effective, minimally invasive alternative to surgery when endoscopic treatment fails to control bleeding from the upper gastrointestinal tract. This article reviews the various transcatheter endovascular techniques and devices that are used in a variety of clinical scenarios for the management of hemorrhagic gastrointestinal emergencies.

Abstract
Objectives. To evaluate the cost-effectiveness of etoricoxib (90 mg) relative to celecoxib (200/400 mg), and the nonselective NSAIDs naproxen (1000 mg) and diclofenac (150 mg) in the initial treatment of ankylosing spondylitis in Norway. Methods. A previously developed Markov state-transition model was used to estimate costs and benefits associated with initiating treatment with the different competing NSAIDs. Efficacy, gastrointestinal and cardiovascular safety, and resource use data were obtained from the literature. Data from different studies were synthesized and translated into direct costs and quality adjusted life years by means of a Bayesian comprehensive decision modeling approach. Results. Over a 30-year time horizon, etoricoxib is associated with about 0.4 more quality adjusted life years than the other interventions. At 1 year, naproxen is the most cost-saving strategy. However, etoricoxib is cost and quality adjusted life year saving relative to celecoxib, as well as diclofenac and naproxen after 5 years of follow-up. For a willingness-to-pay ceiling ratio of 200,000 Norwegian krones per quality adjusted life year, there is a >95% probability that etoricoxib is the most-cost-effective treatment when a time horizon of 5 or more years is considered. Conclusions. Etoricoxib is the most cost-effective NSAID for initiating treatment of ankylosing spondylitis in Norway.

Abstract
OBJECTIVE To evaluate the effectiveness and tolerability of etoricoxib in patients with osteoarthritis (OA) with suboptimal response to existing pain regimens. METHODS A multicenter, prospective, open-label, single-arm study. OA patients (n = 500) taking nonsteroidal anti-inflammatory drugs (NSAIDs) or other analgesics who had inadequate response as determined by their physicians (>or= 40 mm on a 0-100 mm pain scale) were switched directly to etoricoxib 60 mg once daily for 4 weeks without prior medication washout. The primary endpoint was the percentage of patients with >or= 30% improvement in Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) pain walking on a flat surface after 4 weeks of treatment. Other endpoints included WOMAC Pain, Stiffness, and Physical Function subscales, Brief Pain Inventory (BPI), investigator's global assessment of response to therapy (IGART), the Treatment Satisfaction Questionnaire for Medication (TSQM) and Short Form 36 (SF36). Safety and tolerability were assessed by collecting adverse events. RESULTS After switching to etoricoxib, 52% (95% confidence interval: 47%, 57%) of patients reported a clinically meaningful reduction (>or= 30%) for WOMAC pain walking on a flat surface. Disability in daily activities and pain interference were significantly improved (P < 0.0001). IGART scores improved after the switch to etoricoxib (P < 0.05). Results from TSQM demonstrated that patient perceptions of effectiveness, convenience and overall satisfaction increased. Etoricoxib was generally well tolerated in most patients. The most commonly reported adverse event was edema (4.2%). CONCLUSIONS In OA patients experiencing inadequate relief from a wide variety of analgesics, pain, function, quality of life, and treatment satisfaction significantly improved when switched to etoricoxib.

Abstract
Purpose: To study the prescription of oral analgesics for musculoskeletal pain by primary care physicians over a 5-year period in Sweden. Design: A retrospective automatic database review of patient records at four primary health care centers. All prescriptions of NSAIDs, weak opioids, and coprescriptions of gastroprotecting medications to patients with musculoskeletal were retrieved for the period January 1, 2004 to November 11, 2008. Results: A total of 27,067 prescriptions prescribed to 23,457 patients with musculoskeletal pain were analyzed. Of all prescriptions, NSAIDs were the most commonly prescribed analgesic comprising 79%, tramadol was the second most commonly prescribed analgesic comprising 9%, codeine the third most (7%), and dextropropoxyphene the fourth (5%). The proportion of NSAIDs and weak opioids and the proportion of the different weak opioids prescribed showed no change over time. The proportion of nonselective and selective NSAIDs prescribed changed; Coxib prescriptions decreased from 9% to 4% of all analgesics prescribed in 2004–2007 with no change in 2008. Conclusion: NSAIDs were found to be the dominant class of analgesic prescribed by primary care physicians to patients diagnosed as musculoskeletal pain. No change was observed in the proportion of NSAID and weak opioid prescription over the period studied. Prescription of selective Coxibs decreased and was less than 4% in 2008. The impact on gastrointestinal and cardiovascular adverse effects associated with the extensive prescription of NSAIDS for musculoskeletal pain warrants further analysis.

Abstract
To evaluate the cost effectiveness of etoricoxib (90 mg/day) relative to celecoxib (200 or 400 mg/day), and the non-selective NSAIDs naproxen (1000 mg/day) and diclofenac (150 mg/day) in the initial treatment of ankylosing spondylitis (AS) from the UK NHS perspective. A Bayesian cost-effectiveness model was developed to estimate the costs and benefits associated with initiating AS treatment with etoricoxib, celecoxib, diclofenac or naproxen. Efficacy, safety and medical resource and cost data were obtained from the literature. The obtained efficacy estimates were synthesized with a mixed treatment comparison meta-analysis. Treatment benefit and degree of disease activity, as reflected with Bath Ankylosing Spondylitis Functional Index (BASFI) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) scores, were related to QALYs and AS-specific costs (related to BASDAI). Other cost outcomes related to drug acquisition, and gastrointestinal and cardiovascular safety. Uncertainty in the source data was translated into uncertainty in cost-effectiveness estimates and therefore decision uncertainty. Costs and outcomes were discounted at 3.5% per annum. There was a >98% probability that treatment with etoricoxib results in greater QALYs than the other interventions. Over a 30-year time horizon, starting AS treatment with etoricoxib was associated with about 0.4 more QALYs than the other interventions. At 2 years there was a 77% probability that etoricoxib had the lowest cost. This increased to >99% at 30 years. Etoricoxib is expected to save 13 620 UK pounds (year 2007 values) relative to celecoxib (200/400 mg), 9957 UK pounds relative to diclofenac and 9863 UK pounds relative to naproxen. For a willingness-to-pay ceiling ratio of 20 000 UK pounds per QALY, there was a >97% probability that etoricoxib was the most cost-effective treatment. Additional analysis with different assumptions, including celecoxib 200 mg, and ignoring cost-offsets associated with improvements in disease activity, supported these findings. This economic evaluation suggests that, from the UK NHS perspective, etoricoxib is the most cost-effective initial NSAID treatment for AS patients.

Abstract
The efficacy of non-steroidal anti-inflammatory drugs (NSAIDs) for the treatment of inflammation and pain of various origins is well established. Prescribing these drugs, however, remains a challenge because a great variety of gastrointestinal and cardiovascular safety issues need to be considered, particularly in older patients. Recent recommendations suggest that the prescription of non-selective NSAIDs and/or selective cyclo-oxygenase-2 inhibitors (coxibs) may be appropriate in patients with low gastrointestinal risk (no prior gastrointestinal events, no concomitant treatments with other damaging drugs). Gastroprotection is appropriate in patients with gastrointestinal risk factors and in older patients. In patients at high risk for gastrointestinal and cardiovascular events, however, NSAID or coxib prescriptions are contraindicated. Multidimensional impairment is a crucial point in evaluating the clinical outcome of older patients; thus, a comprehensive geriatric assessment is useful in predicting adverse outcomes, including morbidity and mortality.

Abstract
Etoricoxib is a selective cyclo-oxygenase (COX)-2 inhibitor, approved in Europe for the symptomatic treatment of osteoarthritis, rheumatoid arthritis, ankylosing spondylitis and acute gouty arthritis. Etoricoxib provided similar symptomatic relief to nonselective NSAIDs in patients with these conditions, and to celecoxib in patients with osteoarthritis. The drug was associated with fewer uncomplicated upper gastrointestinal (GI) adverse events than nonselective NSAIDs, and was noninferior to diclofenac in terms of the rate of thrombotic cardiovascular (CV) events. Etoricoxib may be considered as a treatment option for patients requiring NSAID therapy, particularly those at risk of upper GI events, after careful consideration of significant risk factors for CV events (including uncontrolled hypertension). As with all NSAIDs, the potential GI and CV risks of treatment with etoricoxib should be weighed against the potential benefits in individual patients, and it should be administered at the lowest effective dose for as short a duration as possible.

Prevention of NSAID-related upper gastrointestinal toxicity: a meta-analysis of traditional NSAIDs with gastroprotection and COX-2 inhibitors. DRUG HEALTHCARE AND PATIENT SAFETY 2009; 1:47-71.

Abstract
Background: Traditional NSAIDs (tNSAIDs) and COX-2 inhibitors (COX-2s) are important agents for the treatment of a variety or arthritic conditions. The purpose of this study was to systematically review the effectiveness of misoprostol, H2-receptor antagonists (H2RAs), and proton pump inhibitors (PPIs) for the prevention of tNSAID related upper gastrointestinal (GI) toxicity, and to review the upper gastrointestinal (GI) safety of COX-2s. Methods: An extensive literature search was performed to identify randomized controlled trials (RCTs) of prophylactic agents used for the prevention of upper GI toxicity, and RCTs that assessed the GI safety of the newer COX-2s. Meta-analysis was performed in accordance with accepted techniques. Results: 39 gastroprotection and 69 COX-2 RCTs met inclusion criteria. Misoprostol, PPIs, and double doses of H2RAs are effective at reducing the risk of both endoscopic gastric and duodenal tNSAID-induced ulcers. Standard doses of H2RAs are not effective at reducing the risk of tNSAID-induced gastric ulcers, but reduce the risk of duodenal ulcers. Misoprostol is associated with greater adverse effects than the other agents, particularly at higher doses. COX-2s are associated with fewer endoscopic ulcers and clinically important ulcer complications, and have fewer treatment withdrawals due to GI symptoms than tNSAIDS. Acetylsalicylic acid appears to diminish the benefit of COX-2s over tNSAIDs. In high risk GI patients, tNSAID with a PPI or a COX-2 alone appear to offer similar GI safety, but a strategy of a COX-2 with a PPI appears to offer the greatest GI safety. Conclusion: Several strategies are available to reduce the risk of upper GI toxicity with tNSAIDs. The choice between these strategies needs to consider patients’ underlying GI and cardiovascular risk.

Abstract
BACKGROUND The safety of NSAIDs is often evaluated by comparison with placebo in clinical trials. AIM To investigate the incidence of gastric and duodenal ulcers (GDU) in placebo arms in NSAID trials over the last three decades. METHODS Randomized placebo-controlled trials of oral NSAIDs from 1975 to 2006 were systematically reviewed. The pooled incidence of GDU in placebo arms was calculated and compared. Meta-regression was used to identify risk factors related to the incidence of the placebo ulcer at the study level. RESULTS Thirty-six studies met inclusion criteria (duration of 6.5 days to 24 weeks). In total, 3.29% GDUs were reported in 36 placebo arms. The incidence of GDU in placebo arms was 0, 4.20% and 3.03% in the studies from 1975-1989, 1990-1999 and 2000-2006 respectively (P > 0.05). Eligible subjects with previous GI events and eligible subjects on co-therapy with low-lose aspirin/corticosteroids were associated with the increase in placebo ulcer incidence after adjusting for other factors. CONCLUSIONS The incidence of GDU in placebo arms has not changed significantly over the last three decades, although has decreased in the past 10 years. Studies show that previous GI events and co-therapy with low-dose aspirin/corticosteroids were associated with increasing GDU in placebo arms.

Abstract
The association between NSAIDs and the presence of upper gastrointestinal (GI) complications is well established. Evidence that acid aggravates NSAID-induced injury provides a rationale for minimizing such damage by acid suppression. Proton pump inhibitors (PPIs) appear to be very effective in treating NSAID-related dyspepsia, and also in healing gastric and duodenal ulcers in patients continuing to receive the NSAID. An analysis of data from comparative studies of PPIs versus ranitidine, misoprostol and sucralfate shows a therapeutic advantage in favour of the PPI. Several studies now confirm the efficacy of co-therapy with PPIs in the short- and long-term prevention of NSAID-induced upper GI injury. PPIs are more effective than histamine H(2)-receptor antagonists at standard dosages in reducing the risk of gastric and duodenal ulcer, and are superior to misoprostol in preventing duodenal but not gastric lesions. However, when balancing effectiveness and tolerance, PPIs may be considered the treatment of choice in the short- and long-term prevention of NSAID-related mucosal lesions. To date, there are only a few published articles dealing with the role of PPIs in the prevention of upper GI complications. Recent epidemiological and interventional studies provide some evidence that PPIs are of benefit. However, more controlled studies using clinical outcomes are needed to establish the best management strategy (PPIs combined with traditional NSAIDs or with cyclo-oxygenase-2 selective inhibitors) especially in patients with multiple risk factors, in patients using concomitant low-dose aspirin, corticosteroids or anticoagulants (high risk group), or in patients with a history of ulcer complications (very high risk group). Furthermore, it should be underlined that Helicobacter pylori infection positively interacts with the gastroprotective effect of PPIs; therefore, the true efficacy of these drugs in preventing NSAID-related ulcer complications should be reassessed without the confounding influence of this microorganism.

Abstract
Arachidonic acid (AA) and its metabolites have recently generated a heightened interest due to growing evidence of their significant role in cancer biology. Thus, inhibitors of the AA cascade, first and foremost COX inhibitors, which have originally been of interest in the treatment of inflammatory conditions and certain types of cardiovascular disease, are now attracting attention as an arsenal against cancer. An increasing number of investigations support their role in cancer chemoprevention, although the precise molecular mechanisms that link levels of AA, and its metabolites, with cancer progression have still to be elucidated. This article provides an overview of the AA cascade and focuses on the roles of its inhibitors and their implication in cancer treatment. In particular, emphasis is placed on the inhibition of cell proliferation and neo-angiogenesis through inhibition of the enzymes COX-2, 5-LOX and CYP450. Downstream effects of inhibition of AA metabolites are analysed and the molecular mechanisms of action of a selected number of inhibitors of catalytic pathways reviewed. Lastly, the benefits of dietary omega-3 fatty acids and their mechanisms of action leading to reduced cancer risk and impeded cancer cell growth are mentioned. Finally, a proposal is put forward, suggesting a novel and integrated approach in viewing the molecular mechanisms and complex interactions responsible for the involvement of AA metabolites in carcinogenesis and the protective effects of omega-3 fatty acids in inflammation and tumour prevention.

Abstract
OBJECTIVE To compare cardiovascular (CV) and other safety and efficacy parameters of etoricoxib 60 and 90 mg, and diclofenac 150 mg. METHODS This double-blind study randomized OA patients to etoricoxib 90 mg, then to 60 mg once daily vs diclofenac 75 mg twice daily; RA patients were randomized to etoricoxib 90 mg once daily or diclofenac 75 mg twice daily. The primary endpoint was non-inferiority of etoricoxib vs diclofenac for thrombotic CV events (95% CI upper bound of hazard ratio <1.30). Other safety and efficacy parameters were evaluated in cohorts of patients based on etoricoxib dose and disease. RESULTS A total of 23 504 patients were randomized with mean treatment duration from 19.4 to 20.8 months. The thrombotic CV risk hazard ratio (HR) (etoricoxib to diclofenac) was 0.96 (95% CI 0.81, 1.15), consistent with non-inferiority of etoricoxib to diclofenac. The cumulative gastrointestinal (GI)/liver adverse events (AEs) discontinuation rate was significantly lower for etoricoxib than diclofenac in each patient cohort; HR (95% CI) of 0.46 (0.39, 0.54), 0.52 (0.42, 0.63) and 0.49 (0.39, 0.62) for the 60 mg OA, 90 mg OA and RA cohorts. The maximum average change in systolic blood pressure (BP) with etoricoxib was 3.4-3.6 mmHg (diastolic BP: 1.0-1.5 mmHg), while diclofenac produced a maximum average change of 0.9-1.9 mmHg (diastolic BP: 0.0-0.5 mmHg). Both agents resulted in similar efficacy regardless of etoricoxib dose. CONCLUSION Long-term etoricoxib use is associated with a risk of thrombotic CV events comparable with that of diclofenac. Compared with diclofenac, etoricoxib demonstrated a greater risk of renovascular AEs, but a more favourable GI/liver tolerability profile.

Abstract
AIMS Digoxin is a commonly prescribed cardiac glycoside with a narrow therapeutic index. The aim was to investigate whether the cyclooxygenase-2 selective nonsteroidal anti-inflammatory drug etoricoxib affects the steady-state pharmacokinetics of digoxin. METHODS This was a double-blind, randomized, placebo-controlled, two-period cross-over study. In each period, 14 healthy volunteers ranging in age from 21 to 35 years received oral digoxin 0.25 mg daily and were randomized to either etoricoxib 120 mg or matching placebo tablets once daily for 10 days. Trough digoxin plasma concentrations were analysed by linear regression to examine digoxin accumulation over time. RESULTS The geometric mean ratios (etoricoxib/placebo) for AUC(0-24h), C(max) and urinary excretion were 1.06 (90% confidence interval 0.97, 1.17), 1.33 (1.21, 1.46) and 1.10 (1.00, 1.20), respectively. The median (range) for digoxin T(max) (h) values with etoricoxib and placebo were 0.5 (0.5, 1.5) and 1.0 (0.5, 1.5), respectively. Steady-state digoxin plasma concentrations were achieved by day 7 in each treatment period. No serious adverse experiences were reported. CONCLUSIONS Although etoricoxib 120 mg did produce an approximately 33% increase in digoxin C(max), this increase does not appear to be clinically meaningful, as cardiotoxicity with digoxin has been associated with elevations in steady-state rather than peak concentrations. From these results, it appears that etoricoxib does not cause any changes in digoxin steady-state pharmacokinetics that would necessitate a dose adjustment.

Abstract
BACKGROUND The large (n = 18 325) Therapeutic Arthritis Research and Gastrointestinal Event Trial (TARGET) study demonstrated a significant gastrointestinal benefit with lumiracoxib 400 mg o.d. (4x the recommended dose in osteoarthritis) vs. naproxen 500 mg b.d. or ibuprofen 800 mg t.d.s. AIM To investigate how early a reduction in ulcer complications could be detected with lumiracoxib vs. nonselective nonsteroidal anti-inflammatory drugs in TARGET. METHODS Pointwise 95% confidence intervals were generated for the between-treatment differences in Kaplan-Meier estimates for definite or probable upper gastrointestinal ulcer complications (ulcer complications) and for all ulcers. RESULTS In patients not on aspirin, there was a significant reduction in all ulcers by day 8 and in ulcer complications by day 16 with lumiracoxib compared with both nonselective nonsteroidal anti-inflammatory drugs combined, by day 6 (all ulcers) and day 14 (ulcer complications) vs. naproxen and by day 32 (all ulcers) and day 33 (ulcer complications) vs. ibuprofen. CONCLUSION Even with short-term use, there are gastrointestinal safety benefits for lumiracoxib vs. nonselective nonsteroidal anti-inflammatory drugs.

Abstract
We determined cyclo-oxygenase-1 and cyclo-oxygenase-2 inhibition in healthy middle-aged subjects (41-65 years) randomly assigned to four 7-day treatment sequences of etoricoxib 90 mg every day, celecoxib 200 mg twice a day, diclofenac 75 mg twice a day, or placebo in a double-blind, randomized, 4-period crossover study. Maximum inhibition of thromboxane B(2) (cyclo-oxygenase-1 activity) in clotting whole blood on day 7 (0-24 hours postdose) was the primary endpoint. Inhibition of lipopolysaccharide-induced prostaglandin E(2) in whole blood (cyclo-oxygenase-2 activity) was assessed on day 7 (0-24 hours postdose) as a secondary endpoint. Diclofenac had significantly greater maximum inhibition of thromboxane B(2) versus each comparator (P < .001); placebo 2.4% (95% confidence interval: -8.7% to 12.3%), diclofenac 92.2% (91.4% to 92.9%), etoricoxib 15.5% (6.6% to 23.5%), and celecoxib 20.2% (11.5% to 28.1%). Prostaglandin E(2) synthesis was inhibited with a rank order of potency of diclofenac > etoricoxib > celecoxib. In summary, at doses commonly used in rheumatoid arthritis, diclofenac significantly inhibits both cyclo-oxygenase-1 and cyclo-oxygenase-2, whereas etoricoxib and celecoxib significantly inhibit cyclo-oxygenase-2 and do not substantially inhibit cyclo-oxygenase-1.
