Effect of renal failure on the pharmacokinetics of ethyl loflazepate (Victan) in man.

The kinetics of ethyl loflazepate were studied in patients with various degrees of renal failure. A strong correlation was noted between urinary excretion of metabolite loflazepate and creatinine clearance. In contrast, elimination half-life and total plasma clearance of the sum of loflazepate + descarboxyloflazepate seemed to be independent of the degree of renal impairment. These results indicate the absence of a risk of accumulation of the 2 main and active metabolites of ethyl loflazepate in patients with renal failure.
