Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminoglycoside antibiotic that irreversibly binds to the 30S ribosomal subunit, causing misreading of mRNA and inhibiting protein synthesis.
Neomycin is an aminoglycoside antibiotic that binds to the 30S ribosomal subunit, inhibiting bacterial protein synthesis. Polymyxin B is a cationic detergent antibiotic that disrupts bacterial cell membrane integrity by interacting with phospholipids. Hydrocortisone is a corticosteroid that suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis.
15 mg/kg/day IM or IV in divided doses every 12 hours. Maximum daily dose: 1.5 g.
Instill 3 to 4 drops into the affected ear(s) 3 to 4 times daily. For otic suspension in adults.

"The serum concentration of Deslanoside can be decreased when it is combined with Kanamycin."
Clinical Note
moderateKanamycin + Acetyldigitoxin
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.
Neomycin: 2-3 hours (in adults with normal renal function); may accumulate in renal impairment. Polymyxin B: 6-8 hours (prolonged in renal impairment: up to 36 hours). Hydrocortisone: 1.2-1.5 hours (terminal).
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%).
Neomycin: >90% unchanged in feces after oral administration; negligible renal excretion. Polymyxin B: 60% renal excretion of unchanged drug; remainder nonrenal. Hydrocortisone: primarily hepatic metabolism, <5% renal excretion unchanged.
