Jbo. Were et Ta. Shapiro, EFFECTS OF PROBENECID ON THE PHARMACOKINETICS OF ALLOPURINOL RIBOSIDE, Antimicrobial agents and chemotherapy, 37(5), 1993, pp. 1193-1196
Allopurinol riboside is an experimental agent for the treatment of lei
shmaniasis and American trypanosomiasis. Previous studies showed that
after oral administration, unexpectedly low levels of allopurinol ribo
side in plasma are attributable to incomplete absorption and rapid ren
al clearance. In this randomized, crossover evaluation in healthy volu
nteers, probenecid reduces the renal clearance of allopurinol riboside
, extends the half-life of allopurinol riboside in plasma, and triples
the levels of allopurinol riboside in plasma.
