The Claim

In patients with chronic kidney disease, treatment with febuxostat compared to allopurinol results in no significant difference in the risk of estimated glomerular filtration rate decline of 30% or more over a 2.5-year follow-up period, after adjustment for baseline kidney function, comorbidities, and medication adherence.

In plain English

Among patients with chronic kidney disease, taking febuxostat or allopurinol leads to the same rate of decline in kidney function over 2.5 years when accounting for initial kidney health, other medical conditions, and adherence to medication.

See the scientific wording

In patients with chronic kidney disease, the risk of estimated glomerular filtration rate decline ≥30% is not significantly different between those treated with febuxostat and those treated with allopurinol, even after adjusting for baseline kidney function, comorbidities, and medication adherence over 2.5 years of follow-up.

Why this might work

Lowering uric acid in the blood with either drug does not change how fast the kidneys lose their ability to filter waste, because the damage to kidney filters comes from other causes that are not affected by uric acid levels.

  1. Study: Comparison of uric acid reduction and renal outcomes of febuxostat vs allopurinol in patients with chronic kidney disease

    For people with kidney disease, taking febuxostat instead of allopurinol doesn’t make their kidneys worse or better over two and a half years — both medicines protect the kidneys equally, even though febuxostat lowers uric acid more.
