CORTISONE ACETATE vs ZYLET
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid with glucocorticoid and mineralocorticoid activity; binds to glucocorticoid receptors, modulating gene expression to suppress inflammation and immune responses.
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.
25-300 mg per day orally, in divided doses every 6-12 hours, depending on condition severity.
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.
