Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Neomycin is an aminoglycoside antibiotic that binds to the 30S ribosomal subunit, causing misreading of mRNA and inhibiting bacterial protein synthesis. Dexamethasone is a corticosteroid that induces phospholipase A2 inhibitory proteins, thereby suppressing prostaglandin and leukotriene synthesis, reducing inflammation.

Ophthalmic: 1-2 drops of the solution or small amount of the ointment (approximately 1/2 inch into the conjunctival sac) every 3-4 hours, or more frequently if needed. Otic: 4 drops into the affected ear 3-4 times daily.
1-2 mg/kg IV every 8 hours for 7-10 days, targeting peak serum concentration of 6-10 mcg/mL and trough <2 mcg/mL.

Neomycin: terminal half-life ~2-3 hours after oral absorption (negligible systemic absorption); in renal impairment, half-life can extend to 12-24 hours. Dexamethasone: terminal half-life ~36-54 hours (mean ~48 hours) in adults.
Terminal elimination half-life is 2-3 hours in patients with normal renal function; may prolong to 20-40 hours in end-stage renal disease
Neomycin is primarily excreted unchanged in feces (~97%) after oral administration, with about 1% absorbed and renally excreted. Dexamethasone is metabolized in liver and excreted renally (~65% as metabolites, 2-5% unchanged) and in feces (~20%).
Primarily renal (glomerular filtration) with 40-70% excreted unchanged in urine within 24 hours; minor biliary/fecal (<5%)
