Safety of Cyclooxygenase-2 Inhibitors in Osteoarthritis: Outcomes of a Systematic Review and Meta-Analysis
Abstract
Objective: Our aim was to assess the safety of cyclooxygenase-2 (COX-2) inhibitors in the management of osteoarthritis (OA) in a systematic review and meta-analysis of randomized, placebo-controlled trials.
Methods: A comprehensive literature search was undertaken in the databases MEDLINE, Cochrane Central Register of Controlled Trials (Ovid CENTRAL) and Scopus. Randomized, double-blind, placebo-controlled, parallel-group trials that assessed adverse events (AEs) with COX-2 inhibitors in patients with OA were eligible for inclusion. Two authors appraised titles, abstracts and full-text papers for suitability and then assessed the studies for random sequence generation, allocation concealment, blinding of participants and personnel, blinding of outcome assessment, incomplete outcome data and selective outcomes reporting. The primary outcomes of interest were gastrointestinal disorders, cardiac disorders, vascular disorders, nervous system disorders, skin and subcutaneous tissue disorders, hepatobiliary disorders, renal and urinary disorders, as well as overall severe and serious AEs, drug-related AEs and mortality. Secondary outcomes were withdrawals due to AEs (i.e. the number of participants who stopped the treatment due to an AE) and total number of AEs (i.e. the number of patients who experienced any AE at least once).
Results: Database searches identified 2149 records from which, after exclusions, 40 trials were included in the meta-analysis. The use of COX-2 inhibitors…
