The amount of urate bound in the absence of drugs was regarded as the baseline and the amounts bound in the presence of various drugs were expressed as percentages of the control values (Fig. 2). It can be seen that probenecid, sulfinpyrazone and sodium salicylate all significantly displaced urate from human albumin binding sites, while colchicine had no effect. 

Ethambutol had no effect on the urinary excretion of sodium or potassium and there was no clinical evidence of volume depletion in patients receiving this agent. The hyperuricemia of ethambutol was not reversed by salicylates in 3 patients in whom this was studied. Ethambutol did not inhibit the effect of probenecid, sulfinpyrazone or iopanoic acid in 3 additional patients.
