Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Tobramycin, an aminoglycoside antibiotic, binds to the 30S ribosomal subunit, causing misreading of mRNA and inhibiting protein synthesis, leading to bacterial cell death.
Netromycin is an aminoglycoside antibiotic that binds to the 30S ribosomal subunit, causing misreading of mRNA and inhibition of protein synthesis in bacteria.
4 IU/kg (1 mg/kg) intramuscularly or subcutaneously once weekly for 4 weeks, then a maintenance dose of 2 IU/kg (0.5 mg/kg) once weekly.
4-6 mg/kg IV once daily for serious infections; 1.5-2 mg/kg IV every 8 hours for gram-negative infections. Administered as intravenous infusion over 30-60 minutes.

Terminal elimination half-life 2-3 hours in patients with normal renal function; prolonged to 20-40 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life is 2-3 hours in adults with normal renal function, but may extend to 24-48 hours in patients with impaired renal function.
Primarily renal excretion of unchanged drug via glomerular filtration; ~90% of absorbed dose excreted in urine within 24 hours; biliary/fecal elimination <5%.
Renal excretion of unchanged drug accounts for 80-90% of elimination via glomerular filtration; biliary/fecal elimination is minimal (<5%).
