The Claim

In men with gout and preserved kidney function, fractional excretion of uric acid does not influence the magnitude of serum urate reduction achieved with febuxostat treatment.

How it works
1 study reviewed
In plain English

In men with gout and normal kidney function, the amount of uric acid cleared by the kidneys does not affect how much febuxostat lowers blood uric acid levels.

See the scientific wording

In men with gout and preserved kidney function, fractional excretion of uric acid (FEUA) does not influence the urate-lowering response to febuxostat, consistent with febuxostat’s hepatic metabolism and minimal renal excretion.

Why this might work

Febuxostat enters the liver and blocks the enzyme that makes uric acid, so less uric acid is produced. The kidneys do not need to remove much of this drug because it is broken down and cleared by the liver, so how well the kidneys excrete uric acid does not change how much uric acid the drug lowers.

  1. Study: Response to Allopurinol and Febuxostat According to the Fractional Excretion of Urate in Men With Gout

    Febuxostat works the same in all men with gout, no matter how well their kidneys get rid of uric acid, because the liver breaks it down instead of the kidneys. The study showed kidney excretion didn’t affect how well febuxostat lowered uric acid levels.
