Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid with potent anti-inflammatory, immunosuppressive, and antiallergic effects. Binds to glucocorticoid receptors, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, and suppress cytokine production.
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.
1-2 drops into the conjunctival sac every 1-2 hours during the day and every 2 hours at night initially, then reduce frequency as inflammation subsides.
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.

Prednisolone: 2-4 hours; clinical context: adrenal suppression lasts 24-36 hours, requiring tapering
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: 70-80% as metabolites; biliary: 10-15%; fecal: <5%
Renal: ~70% as unchanged drug and metabolites; fecal/biliary: ~30%
