Abstract
Sch 21420, and 1-N-HAPA derivative of gentamicin B, was compared to gentamicin, tobramycin and amikacin in a variety of in vitro and in vivo tests. Based on studies with a large number of sensitive and resistant bacteria, it was shown that Sch 21420 has a spectrum and potency essentially the same as that of amikacin. Serum levels in mice, rats and dogs are similar to those of other aminoglycosides. Sch 21420 was markedly less toxic than amikacin in chronic renal function tests in rats and appears to have an advantageously improved therapeutic index compared to amikacin.This publication has 2 references indexed in Scilit:
