STERI-STAT vs ZYLET
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to the 50S ribosomal subunit of bacteria, inhibiting protein synthesis by blocking peptide bond formation and translocation.
Loteprednol etabonate is a corticosteroid that inhibits phospholipase A2 activity, reducing prostaglandin and leukotriene synthesis. Tobramycin is an aminoglycoside antibiotic that binds to the 30S ribosomal subunit, inhibiting bacterial protein synthesis.
Adults: 1 gram intravenously every 8 hours infused over 60 minutes.
One to two drops into the conjunctival sac of the affected eye(s) every 4 to 6 hours. In severe cases, every 1 to 2 hours for the first 24 to 48 hours.

Terminal elimination half-life is 8-12 hours in adults with normal renal function; prolonged to 18-24 hours in moderate renal impairment (CrCl 30-50 mL/min).
ZYLET: not applicable (fixed-dose combination); Loteprednol: 2-3 hours; Tobramycin: 2-3 hours. Clinical context: no accumulation with qid dosing.
Renal excretion of unchanged drug accounts for approximately 95% of elimination; biliary/fecal elimination is minimal (<5%).
Renal (30% unchanged), biliary/fecal (70% as metabolites)
