[Treatment of hyperuricaemia with a combination of allopurinol and benzbromaron (author's transl)].

Three patients with gout and seven with hyperuricaemia, previously untreated, took a single dose of 100 mg allopurinol and 20 mg benzbromaron (as a combined preparation) each morning. There occurred a highly significant decrease in serum uric acid concentration from 430.7 mumol/l (72.4 mg/l) to 268.6 mumol/l (45.2 mg/l), without any significant increase in urinary excretion of uric acid.
