any of a group of antibacterial antibiotics derived from species of Streptomyces; they interfere with the function of bacterial ribosomes. They contain an inositol moiety substituted with two amino or guanidino groups and with one or more sugars or aminosugars. The group includes amikacin, gentamicin, kanamycin, neomycin, streptomycin, and tobramycin. They are used to treat infections caused by gram-negative organisms and are classified as bactericidal agents because of their interference with bacterial replication. All are highly toxic, requiring frequent monitoring of blood serum levels and careful observation of the patient for early signs of toxicity, particularly ototoxicity and nephrotoxicity.

Any one of a group of bacteriocidal antibiotics derived from species of Streptomyces or Micromonosporum and characterized by two or more amino sugars joined by a glycoside linkage to a central hexose; aminoglycosides act by causing misreading and inhibition of protein synthesis on bacterial ribosomes and are effective against aerobic gram-negative bacilli and Mycobacterium tuberculosis. Some commonly used aminoglycosides are streptomycin, neomycin, and gentamicin.

aminoglycosideAny of a family of broad-spectrum antibiotics (amikacin, gentamicin, kanamycin, netilmicin, neomycin, framycetin, streptomycin, tobramycin) which are used primarily against aerobic gram-negative bacteria.
Poorly absorbed per os; poor penetration of CNS-BBB; rapid excretion if kidneys are normal.
Gentamicin, streptomycin, tobramycin.
Dose-related (kidneys, vestibular, auditory and neuromuscular systems), minor skin rash, drug fever, decreased Mg2+, decreased Ca2+, decreased K+; it is common practice to monitor patients receiving AGs.

Any one of a group of antibiotics composed of amino sugars in glycoside linkage which act by interfering with the synthesis of bacterial proteins. It is used in the treatment of infections caused by Gram-negative bacteria. Examples: framycetin, gentamicin, neomycin and tobramycin.
