DEXACORT vs STATROL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a glucocorticoid receptor agonist that modulates gene expression to produce anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppressing cytokine production.
Statrol is a combination antibiotic ointment containing polymyxin B sulfate, neomycin sulfate, and gramicidin. Polymyxin B binds to lipopolysaccharides in the outer membrane of gram-negative bacteria, disrupting membrane integrity. Neomycin inhibits protein synthesis by binding to the 30S ribosomal subunit. Gramicidin alters cell membrane permeability in gram-positive bacteria by forming ion channels.
Oral: 0.75-9 mg/day in divided doses; IV: 0.5-9 mg/day every 6-12 hours; IM: 4-20 mg every 2 weeks.

Plasma terminal elimination half-life is 2.8-3.5 hours in adults, but the biological half-life (duration of HPA axis suppression) is 24-36 hours due to prolonged receptor occupancy
Terminal half-life 12-16 hours in adults; prolonged to 24-30 hours in severe renal impairment (CrCl <30 mL/min).
Renal (approximately 80% as inactive metabolites, <5% unchanged), biliary/fecal (minor, approximately 15-20%)
Renal: 70% unchanged; biliary/fecal: 20% as metabolites, 10% unchanged.
