GARAMYCIN vs NETROMYCIN
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.
Netromycin is an aminoglycoside antibiotic that binds to the 30S ribosomal subunit, causing misreading of mRNA and inhibition of protein synthesis in 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.
4-6 mg/kg IV once daily for serious infections; 1.5-2 mg/kg IV every 8 hours for gram-negative infections. Administered as intravenous infusion over 30-60 minutes.

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 adults with normal renal function, but may extend to 24-48 hours in patients with impaired renal function.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine within 24 hours. Minimal biliary/fecal elimination (<2%).
Renal excretion of unchanged drug accounts for 80-90% of elimination via glomerular filtration; biliary/fecal elimination is minimal (<5%).
