The aminoglycosides and aminocyclitols are bactericidal antibiotics primarily used to treat serious infections caused by aerobic gram-negative bacteria and staphylococci. Amikacin and tobramycin have excellent activity against Pseudomonas aeruginosa. However, the use of aminoglycosides and aminocyclitols has been eclipsed by the development of fluoroquinolones, which have better safety profiles and better distribution kinetics. The aminoglycoside antibiotics-streptomycin, dihydros-treptomycin, kanamycin, gentamicin, tobramycin, amikacin, and neomycin-are large molecules with numerous amino acid groups, making them basic polycations that are highly ionized at physiological pHs. This chapter discusses the mechanism of action, antimicrobial activity, resistance, pharmacokinetic properties, drug interactions, toxicity and adverse effects, dosage considerations and clinical usage of aminoglycoside antibiotics.
