Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminoglycoside antibiotic that irreversibly binds to the 30S ribosomal subunit, causing misreading of mRNA and inhibiting protein synthesis. Also disrupts bacterial cell membrane integrity.
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.
15 mg/kg/day IV or IM divided every 8-12 hours; typical adult dose 500 mg IV/IM every 12 hours or 7.5 mg/kg every 12 hours.
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.

Terminal: 2-3 hours (normal renal function); prolonged to 30-50 hours in anuria; neonates 4-8 hours.
Terminal elimination half-life: 2-3 hours in adults with normal renal function; prolonged in renal impairment (up to 40-50 hours in anuria).
Renal: >90% unchanged via glomerular filtration. Biliary/fecal: <1%.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine within 24 hours. Minimal biliary/fecal elimination (<2%).
