Determination method of allopurinol has been studied by the second derivative oscillopolarography. Well-defined linear relationship between concentrations and the wave height in the range 3 .times. 10-7 .apprx. 1 .times. 10-4 mol/L and 5 .times. 10-7 .apprx. 1 .times. 10-4 mol/L was observed, respectively, in 0.50 mol/L H2SO4 and pH 5.5 HAc-NaAc buffer. The contents of allopurinol in tablets and urine were determined. The character of the electrode reaction was explored preliminarily.
