Aminoglycoside antibiotic that binds to the 30S ribosomal subunit, causing misreading of mRNA and inhibiting bacterial protein synthesis.
Aminoglycoside antibiotic; binds to 30S ribosomal subunit, causing misreading of mRNA and inhibiting bacterial protein synthesis.
3-6 mg/kg/day IV in 2-3 divided doses every 8-12 hours; adjust based on serum levels and renal function.
Adults: Tobramycin 3-5 mg/kg/day IV divided every 8 hours, or 5-7 mg/kg/day IV once daily. For inhalation: 300 mg nebulized twice daily.

Terminal elimination half-life is 2-3 hours in patients with normal renal function. Prolonged to 24-48 hours in anuria. Clinical context: Dosing interval adjustment required in renal impairment to avoid toxicity.
Terminal elimination half-life is 2-3 hours in patients with normal renal function; extends to 24-100 hours in severe renal impairment (CrCl <10 mL/min), requiring dose adjustment.
Renal excretion of unchanged drug accounts for >90% of elimination. Approximately 10% is excreted in bile.
Primarily renal (glomerular filtration) with 90-95% excreted unchanged in urine within 24 hours; biliary/fecal <1%.
