Renal function and the disposition of antidepressants and their metabolites.
Reports of plasma concentrations of antidepressants and their metabolites in patients with reduced renal function have been reviewed. The consequences of alteration of various pharmacokinetic factors on drug and metabolite concentrations have been compared with the observed data. Concentrations of drugs that are more than 95 percent metabolized are not altered by decreased renal function. Concentrations of drugs that are mostly excreted unchanged in urine are greatly increased in patients with reduced renal function. Concentrations of metabolites that account for 10 percent or more of the dose of a parent drug in urine are usually increased. In general, the observations can be explained without hypothesizing an effect of reduced renal function on clearance by metabolism.
