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, inhibiting protein synthesis and causing bacterial cell death by disrupting the cytoplasmic membrane.
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 g orally 4 times daily (8-16 g/day) for hepatic encephalopathy or intraluminal infection; 0.5-1 g orally 4 times daily for preoperative bowel preparation.
