Consumers and health professionals are advised that an increased risk of death has been observed in a study of gout patients with pre-existing major cardiovascular disease who were treated with febuxostat tablets compared to allopurinol tablets (another medicine used to treat gout).
Febuxostat, which is marketed in Australia under the brand name Adenuric, is a prescription medicine used to treat adults with chronic gout.
The Cardiovascular Safety of Febuxostat and Allopurinol in Patients with Gout and Cardiovascular Morbidities (CARES) study was a long-term study involving more than 6000 patients with gout and pre-existing major cardiovascular disease. It compared the cardiovascular safety of febuxostat with allopurinol. The study found that, while the risk of combined cardiovascular events was not increased compared to allopurinol, patients taking febuxostat had a higher risk of death, and specifically heart-related death, compared to patients who took the other medicine.
The Product Information (PI) for febuxostat previously included a warning that it was not recommended for patients with ischaemic heart disease or congestive heart failure. In response to the CARES study, this has been strengthened to include all patients with pre-existing major cardiovascular disease. To highlight the seriousness of this precaution, a boxed warning has been added to both the febuxostat PI and Consumer Medicine Information (CMI).
