Uricosuric effect of fenofibrate in healthy volunteers.

The uricosuric properties of a single oral dose (300 mg) of fenofibrate, or isopropyl-[4'-(p-chlorobenzoyl)-2-phenoxy-2-methyl] propionate (LF 178), a new hypolipidemic drug, have been investigated versus placebo, benzbromarone, with and without urine alkalinization, in ten normouricemic male volunteers, following a crossover design. Twofold increased uric acid clearance values were obtained after fenofibrate and fourfold increased values after benzbromarone. The ratio urinary uric acid/urinary creatinine (UUA/UCr) was enhanced after fenofibrate and benzbromarone versus placebo. The urine alkalinization with fenofibrate intake did increase this ratio to a higher extent.
