GARAMYCIN vs GENTAMICIN SULFATE
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 binds to the 30S ribosomal subunit, causing misreading of mRNA and inhibiting protein synthesis. Also disrupts bacterial cell membrane integrity.
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.
1-2 mg/kg IV every 8 hours or 3-5 mg/kg IV every 24 hours for extended-interval dosing; typical duration 7-10 days.

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: 2-4 hours in patients with normal renal function; prolonged to 24-72 hours in renal impairment.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine within 24 hours. Minimal biliary/fecal elimination (<2%).
Renal excretion of unchanged drug accounts for >90% of elimination; biliary/fecal <2%.
