M04: Antigout preparations
ATC M04 antigout preparations for modelers: urate is a turnover problem.
Part of M: Musculo-skeletal system.
Urate is a turnover problem. Serum urate under febuxostat is fitted with an indirect response model [1]; such a model predicted real-world urate with r = 0.68, rising to 0.77 once comorbidities, eGFR and loop diuretics were accounted for [2].
