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.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
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.
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.
What the research says
1 studyFebuxostat 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.
