Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminoglycoside antibiotic that irreversibly binds to the 30S ribosomal subunit, inhibiting protein synthesis and causing mRNA misreading.
Aminoglycoside antibiotic that binds to the 30S ribosomal subunit, causing misreading of mRNA and inhibiting protein synthesis, leading to bacterial cell death. Bactericidal against Gram-negative aerobes.
15 mg/kg/day IM or IV divided every 8-12 hours; typical adult dose: 500 mg IM every 12 hours or 7.5 mg/kg every 12 hours. Maximum total daily dose: 1.5 g.
5-7 mg/kg IV q24h (extended-interval) or 1.5-2.5 mg/kg IV q8h (traditional dosing) for serious Gram-negative infections; adjust based on therapeutic drug monitoring.

Terminal elimination half-life is 2-4 hours in adults with normal renal function; prolonged to 30-60 hours in severe renal impairment (CrCl <10 mL/min).
Terminal elimination half-life of 2–3 hours in patients with normal renal function; prolonged to 24–60 hours in anuria/end-stage renal disease. In neonates, half-life may be 4–12 hours depending on gestational age.
Renal excretion of unchanged drug accounts for 80-90% of elimination; minor biliary excretion (<1%) and fecal elimination (<1%).
Primarily renal excretion of unchanged drug via glomerular filtration; >90% of dose recovered in urine within 24 hours. Biliary/fecal elimination is minimal (<1%).
