First received: January 5, 2010
Last updated: January 5, 2011
Last verified: January 2011
This is a randomized, double-blind, 3-period 3-treatment crossover followed by a 2-period 2-treatment crossover, phase 2 study in patients with documented hyperuricemia to evaluate the effect of tranilast on allopurinol pharmacokinetics (PK) and pharmacodynamics (PD) and to evaluate the effect of allopurinol on tranilast PK and PD as measured by reduction in serum uric acid levels.
