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, causing misreading of mRNA and inhibition of protein synthesis, leading to bacterial 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/day IV or IM in 3 divided doses every 8 hours for serious infections; may use once-daily dosing (5 mg/kg IV every 24 hours) for certain indications.
Intramuscular: 15 mg/kg/day (max 1 g/day) divided every 12 hours; intraperitoneal: 1 g/dialysis cycle; intrathecal: 1 mg/kg/day.

Terminal elimination half-life: 2-3 hours in adults with normal renal function; prolonged in renal impairment (up to 40-50 hours in anuria).
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.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine within 24 hours. Minimal biliary/fecal elimination (<2%).
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.
