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.
Tobramycin is an aminoglycoside antibiotic that binds to the 30S ribosomal subunit, causing misreading of mRNA and inhibiting protein synthesis in susceptible bacteria.
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.
3-5 mg/kg/day IV divided every 8 hours or 5-7 mg/kg IV once daily for adults with normal renal function.

Terminal elimination half-life: 2-3 hours in adults with normal renal function; prolonged in renal impairment (up to 40-50 hours in anuria).
2-3 hours in patients with normal renal function; prolonged to 24-60 hours in anuria. Half-life is directly correlated with creatinine clearance.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine within 24 hours. Minimal biliary/fecal elimination (<2%).
