Probenecid inhibits the renal clearance and renal glucuronidation of nalidixic acid

Abstract: The aim of this pilot study was to demonstrate the possible inhibitory effect of probenecid on the renal glucuronidation and on the renal clearance of nalidixic acid in a human volunteer. Under acidic urine conditions, hardly any nalidixic acid is excreted unchanged (0.2%). It is excreted as acyl glucuronide (53.4%), 7-hydroxymethylnalidixic acid (10.0%), the latter's acyl glucuronide 30.9%, and 7-carboxynalidixic acid (4.2%). Under probenecid co-medication the renal glucuronidation of nalidixic acid is reduce… Show more

“…In particular, the renal elimination of a number of OAT substrates, including famotidine (Inotsume et al, 1990), cidofovir (Cundy et al, 1995), furosemide (Vree et al, 1995), and ciprofloxacin (Jaehde et al, 1995), is slowed in the presence of the well established OAT inhibitor probenecid. However, due to overlap in substrate selectivity between OAT1, OAT3, and other clearance mechanisms, such as metabolism and other transporters, it is difficult to solely implicate renal OATs in DDIs.…”

“…This should be further confirmed by comparing in vivo pharmacokinetics in monkeys and humans. In addition to famotidine, inhibition of renal elimination by probenecid has been reported for benzylpenicillin (Overbosch et al, 1988), cephalosporins (Shitara et al, 2005), oseltamivir (its active metabolite Ro 64-0802) (Hill et al, 2002), furosemide (Vree et al, 1995), bumetanide (Lau et al, 1983), ciprofloxacin (Jaehde et al, 1995), enalapril/enalaprilat (Noormohamed et al, 1990), and fexofenadine (YasuiFurukori et al, 2005). Among these drugs, benzylpenicillin (Tahara et al, 2005), cephalosporins (Jung et al, 2002;Uwai et al, 2002), oseltamivir (its active metabolite Ro 64-0802) (Hill et al, 2002), furosemide, and bumetanide (Hasannejad et al, 2004) have been reported to be substrates of OAT1 and/or OAT3.…”
