Background Coxibs cardiovascular (CV) safety continues being a current issue after rofecoxib worldwide withdrawal in 2004. Objective To evaluate the cardiovascular and gastrointestinal (GI) risk of coxibs through case/non-case study. Setting The Spanish Pharmacovigilance System for Human Use Drugs (FEDRA) and the Uppsala Monitoring Centre (VigiBase) databases. Method We identified adverse drug reactions (ADRs) cases reported under the MedDRA system organ classes of "cardiac disorders", "vascular disorders", "nervous system disorder" and "gastrointestinal disorders". Disproportionality was considered when the following criteria were met simultaneously: proportional reporting ratio (PRR) ≥ 2, 95% confidence interval lower limit of reporting odds ratio (ROR) > 1, Chi square test (χ 2) ≥ 4; and number of ADR reports (n rep.) > 3. Main outcome measure Potential disproportionality between cardiovascular and GI ADRs as reported to FEDRA and VigiBase and the use of coxibs. Results We found association between coxibs and CV-ADRs in FEDRA [PRR 2.11 (95% CI 1.97-2.27); ROR 2.53 (95% CI 2.29-2.89); χ 2 367.81; n rep., 561] and VigiBase [PRR 2.67 (95% CI 2.64-2.71); ROR 3.26 (95% CI 3.20-3.31); χ 2 23,950.93; n rep., 21,047]; and between coxibs and GI-ADRs in VigiBase [PRR 2.91 (95% CI 2.84-2.97); ROR 3.08 (95% CI 3.01-3.16); χ 2 8762.82; n rep. 6954]. No association was found between coxibs and GI-ADRs in FEDRA. Conclusion The association found support a potential coxibs class effect in terms of cardiovascular safety. Classical NSAIDs GI risk may be higher than that for coxibs.

Background: The risk of upper gastrointestinal (GI) complications associated with the use of NSAIDs is a serious public health concern. The risk varies between individual NSAIDs; however, there is little information on the risk associated with some NSAIDs and on the impact of risk factors. These data are necessary to evaluate the benefit-risk of individual NSAIDs for clinical and health policy decision making. Within the European Community's Seventh Framework Programme, the Safety Of non-Steroidal anti-inflammatory drugs (NSAIDs) [SOS] project aims to develop decision models for regulatory and clinical use of individual NSAIDs according to their GI and cardiovascular safety. Objective: The aim of this study was to conduct a systematic review and meta-analysis of observational studies to provide summary relative risks (RR) of upper GI complications (UGIC) associated with the use of individual NSAIDs, including selective cyclooxygenase-2 inhibitors. Methods: We used the MEDLINE database to identify cohort and case-control studies published between 1 January 1980 and 31 May 2011, providing adjusted effect estimates for UGIC comparing individual NSAIDs with non-use of NSAIDs. We estimated pooled RR and 95% CIs of UGIC for individual NSAIDs overall and by dose using fixed-and random-effects methods. Subgroup analyses were conducted to evaluate methodological and clinical heterogeneity between studies. Results: A total of 2984 articles were identified and 59 were selected for data abstraction. After review of the abstracted information, 28 studies met the
Coxibs Refocus Attention on the Cardiovascular Risks of Non-Aspirin NSAIDs
American journal of cardiovascular drugs : drugs, devices, and other interventions, 2017
Non-steroidal anti-inflammatory drugs (NSAIDs) were differentiated from steroidal anti-inflammatory medicines to help clinicians who needed to use anti-inflammatory agents that were safer than steroids. With market entry of rofecoxib in 1999, NSAIDs were then further classified into traditional NSAIDs and cyclooxygenase (COX)-2 inhibitors (coxibs), the latter posing potentially fewer gastrointestinal risks. In 2005, rofecoxib was withdrawn from the market because of concerns about the risk of heart attack and stroke with long-term use, and clinical practice began focusing more on the cardiovascular versus gastrointestinal safety of coxibs. Since then, many coxibs have remained unapproved by the US FDA or have been removed from the market. This article explains how coxibs refocused attention on the cardiovascular safety of NSAIDs and the general implications of that. COX-2 activity/specificity is one factor associated with increased cardiovascular risks; however, these risks cannot b...

The use of cyclo-oxygenase 2 selective nonsteroidal anti-inflammatory drugs (NSAIDs) is associated with increased risk of acute myocardial infarction (AMI). The association between the risks of AMI with nonselective NSAIDs is less clear. We reviewed the published evidence and assessed the risk of AMI with nonselective NSAIDs. We performed a meta-analysis of all studies containing data from population databases that compared the risk of AMI in NSAID users with that in non-users or remote NSAID users. The primary outcome was objectively confirmed AMI. Fourteen studies met predefined criteria for inclusion in the meta-analysis. Nonselective NSAIDs as a class was associated with increased AMI risk (relative AMI risk 1.19, 95% confidence interval [CI] 1.08 to 1.31). Similar findings were found with diclofenac (relative AMI risk 1.38, 95% CI 1.22–1.57) and ibuprofen (relative AMI risk 1.11, 95% CI 1.06 to 1.17). However, this effect was not observed with naproxen (relative AMI risk 0.99, 95% CI 0.88–1.11). In conclusion, based on current evidence, there is a general direction of effect, which suggests that at least some nonselective NSAIDs increase AMI risk. Analysis based on the limited data available for individual NSAIDs, including diclofenac and ibuprofen, supported this finding; however, this was not the case for naproxen. Nonselective NSAIDs are frequently prescribed, and so further investigation into the risk of AMI is warranted because the potential for harm can be substantial.

To provide an updated document assessing the global, NSAID-specific, and time dependent risk of gastrointestinal (GI) complications through meta-analyses of high quality studies. Methods: An exhaustive systematic search was performed. Inclusion criteria were: RCT or controlled study, duration of 5 days at least, inactive control, assessment of minor or major NSAID adverse effects, publication range January 1985 to January 2003. The publications retrieved were assessed during a specifically dedicated WHO meeting including leading experts in all related fields. Statistics were performed conservatively. Meta-regression was performed by regressing NSAID adjusted estimates against study duration categories. Results: Among RCT data, indolic derivates provided a significantly higher risk of GI complications related to NSAID use than for non-users: RR = 2.25 (1.00; 5.08
