Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Gentamicin is an aminoglycoside antibiotic that binds to the 30S ribosomal subunit of susceptible bacteria, inhibiting protein synthesis and causing misreading of mRNA, leading to cell death.
Aminoglycoside antibiotic that irreversibly binds to the 30S ribosomal subunit, inhibiting protein synthesis by causing misreading of mRNA and preventing initiation complex formation.
Gentamicin 3-5 mg/kg IV or IM once daily for serious infections; alternatively, 1.5-2 mg/kg IV or IM every 8 hours.
Intramuscular: 15 mg/kg/day (max 1 g/day) divided every 12 hours; intraperitoneal: 1 g/dialysis cycle; intrathecal: 1 mg/kg/day.

2-3 hours (normal renal function); may extend to 24-48 hours in severe renal impairment, necessitating dose adjustment.
Terminal elimination half-life is 2-3 hours in patients with normal renal function. In anuria or severe renal impairment, half-life may extend to 50-100 hours. Neonates have a prolonged half-life of 5-10 hours due to immature renal function.
Renal: over 90% unchanged via glomerular filtration; minor biliary (<1%).
Primarily renal excretion via glomerular filtration; 80-98% of the dose is excreted unchanged in urine within 24 hours. Minor biliary excretion (less than 1%). Fecal excretion is negligible.
