Renal excretion is the major pathway for elimination of many clinically used drugs and xenobiotics. We estimated the genetic component (r(GC)) contributing to variation in renal clearance for six compounds (amoxicillin, ampicillin, metformin, terodiline, digoxin and iohexol) using Repeated Drug Application methodology. Data were obtained from published literature. The r(GC) values of renal clearance of metformin, amoxicillin, and ampicillin, which undergo transporter-mediated secretion, ranged from 0.64-0.94. This finding suggests that variation in the renal clearance of these drugs has a strong genetic component. Additionally, the r(GC) values of renal clearance of metformin, amoxicillin, and ampicillin were similar to previously reported r(GC) values for metabolism. By contrast, the r(GC) values of renal clearance for iohexol, digoxin, and terodiline were low (0.12-0.37). Renal clearance of these compounds occurs mainly through passive processes (e.g. glomerular filtration and passive secretion/reabsorption). The low r(GC) values of iohexol, digoxin and terodiline suggest that environmental factors may contribute to variation in their renal clearance. (C) 2003 Lippincott Williams Wilkins.
