Single dose study of febuxostat (80 mg) in healthy subjects.

This study looks at how a single dose of febuxostat (80 mg) — a medication used to treat gout by lowering uric acid levels — behaves in the body of healthy volunteers. Researchers want to measure how it is absorbed, processed, and cleared by the body (pharmacokinetics), and how it affects uric acid handling in the kidneys (pharmacodynamics). This type of study is important for understanding the ideal dose and any timing of effect. Participants are healthy adults who take a single tablet and provide blood and urine samples.
