due to the increasing number of new cephalosporins and use of aminoglycoside-cephalosporin combinations , we determined the in vitro stability of 28 aminoglycoside-cephalosporin combinations ( gentamicin sulfate , tobramycin sulfate , netilmicin sulfate [ 10 micrograms/ml ] , and amikacin [ 20 micrograms/ml ] in combination with cefazolin sodium , cefoxitin sodium , cefoperazone sodium , cefotaxime sodium , ceftazidime acid pentahydrate , cefsulodin sodium , or cefpiramide sodium at 100 , 200 , and 300 micrograms/ml ) .
