"Renal function, as reflected by glomerular filtration rate and tubular secretion, decreases steadily with increasing age. 16 There is a 6-10 percentdecrease in renal function per decade after age 40, such that, even a healthy 70 year old male can have a 40-50percent decline of renal function. 7 Drugs which are cleared primarily by the kidneys will, therefore, take longer to be excreted."
