Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Neomycin is an aminoglycoside antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit. Hydrocortisone is a corticosteroid that exerts anti-inflammatory and immunosuppressive effects by binding to glucocorticoid receptors and modulating gene expression.
Neomycin is an aminoglycoside antibiotic that binds to the 30S ribosomal subunit, causing misreading of mRNA and inhibiting protein synthesis. Dexamethasone is a potent corticosteroid with glucocorticoid and mineralocorticoid activity that binds to the glucocorticoid receptor, modulating gene expression to suppress inflammation and immune responses.
Apply topically to affected area twice daily.
1-2 drops into conjunctival sac every 1-2 hours during the day and every 2-4 hours at night for severe conditions; for mild conditions, 1-2 drops 4-6 times daily. Ophthalmic suspension.

2–3 hours (terminal elimination half-life of hydrocortisone); clinically, duration of action is longer due to intracellular receptor binding.
Terminal elimination half-life: 3-4 hours for neomycin; 6-8 hours for dexamethasone. Clinical context: Neomycin accumulates with renal impairment; dexamethasone has prolonged effects in hepatic dysfunction.
Renal excretion of hydrocortisone metabolites (primarily conjugated as glucuronides and sulfates) accounts for >90% of elimination; <5% biliary/fecal.
Renal: ~70% as unchanged drug and metabolites; fecal/biliary: ~30%
