title: Cochlear toxicity of butikacin (UK-18,892), a new semisynthetic aminoglycoside antibiotic, in guinea pigs.
abstract: The cochleotoxic potential of butikacin (UK-18,892), a new semisynthetic aminoglycoside, has been evaluated in neonatal guinea pigs in comparison with amikacin, gentamicin, and kanamycin A. All compounds produced a dose-related increase of the mean threshold sound intensity required to elicit Preyer's reflex. Butikacin produced a similar level of cochlear toxicity to that of kanamycin A, but tended to be less cochleotoxic than amikacin. Gentamicin was the least cochleotoxic.
