Answer

Aminoglycosides

Aminoglycosides primarily act by binding to 16S ribosomal RNA within the 30S ribosomal subunit. They have mainly bactericidal activity against susceptible aerobic gram-negative bacilli.

Gentamicin

Although newer antibiotics are available, aminoglycosides such as gentamicin remain significant in treating severe infections. Aminoglycosides inhibit protein synthesis by irreversibly binding to the 30S ribosomal subunit. In meningitis or gram-negative meningitides, it must be administered intrathecally because of its poor CNS penetration. Dosing regimens are numerous; the dose is adjusted on the basis of the creatinine clearance and changes in the volume of distribution.

Streptomycin

Streptomycin has bactericidal action and inhibits bacterial protein synthesis. Susceptible organisms include Mycobacterium tuberculosis, Pasteurella pestis, Francisella tularensis, Haemophilus influenzae, Haemophilus ducreyi, donovanosis (granuloma inguinale), Brucella species, Klebsiella pneumoniae, Escherichia coli, Proteus species, Aerobacter species, Enterococcus faecalis, and Streptococcus viridans (in endocarditis, with penicillin). Streptomycin is always given as part of a total antituberculosis regimen.
