[Cefaclor dosage change with renal dysfunction].

Abstract

Serum and/or urine levels of cefaclor (CCL) were studied in 4 patients during the therapy with CCL. In patients with severely impaired renal function, moderately higher serum and urine levels of CCL persisted, serum half-lives of CCL were moderately prolonged and urinary excretion of CCL slightly decreased. Although dosage modification of CCL is necessary in patients with renal dysfunction, multiple doses of 250 mg every 8 hours may be safe and effective even in patients with impaired renal function.
