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.
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 IV or IM once daily for serious infections; alternatively, 1.5-2 mg/kg IV or IM every 8 hours.
3-5 mg/kg/day IV divided every 8 hours or 5-7 mg/kg IV once daily for adults with normal renal function.

2-3 hours (normal renal function); may extend to 24-48 hours in severe renal impairment, necessitating dose adjustment.
2-3 hours in patients with normal renal function; prolonged to 24-60 hours in anuria. Half-life is directly correlated with creatinine clearance.
Renal: over 90% unchanged via glomerular filtration; minor biliary (<1%).
Primarily renal (glomerular filtration) with >90% excreted unchanged in urine within 24 hours; minimal biliary/fecal (<1%).
