Use

Introduced in 1976, tobramycin sulfate (Nebcin) is the mostactive of the chemically related aminoglycosides called nebramycinsobtained from a strain of Streptomyces tenebrarius Five members of the nebramycin complex have beenidentified chemically.Factors 4 and 4＇ are 6＂-O-carbamoylkanamycin B andkanamycin B, respectively; factors 5＇ and 6 are 6＂-O-carbamoyltobramycinand tobramycin; and factor 2 isapramycin, a tetracyclic aminoglycoside with an unusual bicycliccentral ring structure. Kanamycin B and tobramycinprobably do not occur in fermentation broths per se but areformed by hydrolysis of the 6-O＂-carbamoyl derivatives inthe isolation procedure.The most important property of tobramycin is its activityagainst most strains of P. aeruginosa, exceeding that of gentamicinby twofold to fourfold. Some gentamicin-resistantstrains of this troublesome organism are sensitive to tobramycin,but others are resistant to both antibiotics. OtherGram-negative bacilli and staphylococci are generally moresensitive to gentamicin. Tobramycin more closely resembleskanamycin B in structure (it is 3＇-deoxykanamycin B).
