Abstract

The effects of pyrazinamide, probenecid, and benzbromarone on renal excretion of oxypurinol were investigated. Pyrazinamide decreased the mean (SEM) fractional clearance of oxypurinol from 19.2 (2.1) to 8.8 (1.5). Probenecid increased the fractional clearance of oxypurinol from 14.1 (3.5) to 24.8 (4.1). Benzbromarone increased the fractional clearance of oxypurinol from 15.6 (2.3) to 33.8 (2.8). These results suggest that oxypurinol may be secreted by 'an organic acid system' and that oxypurinol is reabsorbed at a putative postsecretory site of the renal tubules.

摘要

研究了吡嗪酰胺、丙磺舒和苯溴马隆对氧嘌呤醇肾排泄的影响。吡嗪酰胺使氧嘌呤醇的平均(标准误)分数清除率从19.2(2.1)降至8.8(1.5)。丙磺舒使氧嘌呤醇的分数清除率从14.1(3.5)增至24.8(4.1)。苯溴马隆使氧嘌呤醇的分数清除率从15.6(2.3)增至33.8(2.8)。这些结果表明,氧嘌呤醇可能通过“有机酸系统”分泌,且氧嘌呤醇在肾小管假定的分泌后部位被重吸收。
