Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to the 30S ribosomal subunit, causing misreading of mRNA and inhibition of protein synthesis; bactericidal against gram-negative aerobes.
Aminoglycoside antibiotic that irreversibly binds to the 30S ribosomal subunit, causing misreading of mRNA and inhibiting protein synthesis.
5-7 mg/kg/day IV or IM in divided doses every 8 hours; for serious infections, up to 5 mg/kg/day IV in 3 divided doses.
15 mg/kg/day IM or IV in divided doses every 12 hours. Maximum daily dose: 1.5 g.

2-3 hours in adults with normal renal function; prolonged to 24-48 hours in anuria; adjust dosing based on renal function.
Clinical Note
moderateKanamycin + Digoxin
"The serum concentration of Digoxin can be decreased when it is combined with Kanamycin."
Clinical Note
moderateGentamicin + Digoxin
"The serum concentration of Digoxin can be decreased when it is combined with Gentamicin."
Clinical Note
moderateKanamycin + Digitoxin
"The serum concentration of Digitoxin can be decreased when it is combined with Kanamycin."
Clinical Note
moderateGentamicin + Digitoxin
Terminal elimination half-life is 2-4 hours in patients with normal renal function (creatinine clearance >80 mL/min). In anuria, half-life may extend to 50-100 hours, necessitating dose adjustment based on renal function.
Primarily renal (glomerular filtration): 90-95% unchanged in urine over 24 hours; biliary/fecal: <2%.
Primarily renal excretion via glomerular filtration; approximately 80-90% of administered dose is excreted unchanged in urine within 24 hours. Biliary/fecal excretion is minimal (<1%).
