AEROSPORIN vs BLEPH-30
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Polymyxin B binds to the lipid A portion of bacterial lipopolysaccharides, disrupting the outer membrane permeability and causing bacterial cell death. It is primarily active against Gram-negative bacteria.
BLEPH-30 is a topical formulation containing 30% sulfacetamide sodium, a sulfonamide antibiotic that inhibits bacterial dihydropteroate synthase, interfering with folic acid synthesis and exerting bacteriostatic activity against susceptible organisms.
Polymyxin B sulfate: 1.5-2.5 mg/kg/day intravenously divided every 12 hours, or 25,000-30,000 units/kg/day intramuscularly divided every 12 hours. Ophthalmic: 1-2 drops in affected eye every 4 hours. Topical: Apply to affected area 3-4 times daily.
One drop to the affected eye(s) every 12 hours. Not to exceed 2 drops per eye per day.

Terminal elimination half-life is approximately 2-3 hours in adults with normal renal function; prolonged to 20-40 hours in severe renal impairment (CrCl <10 mL/min), necessitating dose adjustment.
Terminal elimination half-life is approximately 2.5 hours in adults with normal renal function; clinically, dosing intervals may need adjustment in renal impairment.
Primarily renal excretion of unchanged drug via glomerular filtration. Approximately 60-70% of an intravenous dose is recovered in urine within 24 hours; minimal biliary/fecal elimination (<5%).
Primarily renal excretion of unchanged drug, accounting for approximately 90% of elimination; minor biliary/fecal route (<10%).
