To determine the postantibiotic effect of aminoglycosides, two methods are currently being used to remove the test drug: repeated washing and dilution. An enzymatic inactivation method of removing gentamicin and tobramycin was developed and compared with the dilution method. This enzymatic method provides a rapid and simple alternative method of removing aminoglycosides which results in reliable postantibiotic-effect values.
