DEXTENZA vs FERNISOLONE-P
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a corticosteroid with glucocorticoid activity that binds to the glucocorticoid receptor, leading to inhibition of inflammatory mediators such as prostaglandins and leukotrienes, and suppression of immune cell migration and activation.
FERNISOLONE-P is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators like prostaglandins and leukotrienes.
Insert 0.4 mg intracanalicularly (into the lacrimal punctum) as a single dose; releases dexamethasone over 30 days.
5-60 mg orally once daily or in divided doses; intravenous, intramuscular, or intra-articular administration per specific indication.

The terminal elimination half-life of dexamethasone from plasma after systemic absorption is approximately 3-4 hours. However, Dextenza provides sustained local delivery to the ocular surface; the insert releases dexamethasone over 30 days, with therapeutic levels maintained throughout.
3.5 hours; in renal impairment (CrCl <30 mL/min) may extend to 8-10 hours, requiring dose adjustment
Dextenza (dexamethasone ophthalmic insert) is administered intracanalicularly; systemic absorption is minimal. Following release into the tear film, the drug is primarily eliminated via nasolacrimal drainage and subsequent gastrointestinal absorption with hepatic metabolism. Renal excretion accounts for <5% of the dose as unchanged drug; biliary/fecal elimination is negligible.
Renal: 70% as unchanged drug; biliary/fecal: 20% as metabolites; 10% other
