Diclofenac Under Fire for Cardiovascular Risk

By DocWire News Editors - Last Updated: September 11, 2023

Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID) used to treat mild-to-moderate pain. It can also be taken to help relieve symptoms of arthritis (inflammation, swelling, stiffness, and joint pain), osteoarthritis, or rheumatoid arthritis. It can also be used to treat ankylosing spondylitis. However, a recent study published in BMJ reviews that cardiovascular risks of using diclofenac.

In this study, researchers compared the cardiovascular risks of diclofenac initiation with initiation of other traditional non-steroidal anti-inflammatory drugs, initiation of paracetamol, and no initiation. This study included a series of 252 nationwide cohort studies, each mimicking the strict design criteria of a clinical trial. In order to compute the intention to treat hazard ratio of major adverse cardiovascular events within 30 days of initiation, Cox proportional hazards regression was used. 

According to study results, the adverse event rate among diclofenac initiators increased by 50% compared with non-initiators (incidence rate ratio 1.5, 95% confidence interval 1.4 to 1.7), 20% compared with paracetamol or ibuprofen initiators (both 1.2, 1.1 to 1.3), and 30% compared with naproxen initiators (1.3, 1.1 to 1.5). 

“Diclofenac poses a cardiovascular health risk compared with non-use, paracetamol use, and use of other traditional non-steroidal anti-inflammatory drugs,” the researchers concluded.
