Gastrointestinal safety of etoricoxib in osteoarthritis and rheumatoid arthritis: A meta-analysis.

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).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.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.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.
