INVELTYS vs PRED FORTE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid; modulates inflammatory response by binding to glucocorticoid receptors, altering gene expression and suppressing pro-inflammatory cytokines.
Corticosteroid that binds to glucocorticoid receptors, causing inhibition of phospholipase A2, arachidonic acid release, and synthesis of inflammatory mediators. Reduces inflammation by suppressing leukocyte infiltration and cytokine production.
Instill 1 drop into the affected eye(s) four times daily for 14 days, then taper as clinically indicated.
1-2 drops in the conjunctival sac every 1-2 hours during the day and every 4 hours at night initially, then taper to every 4-8 hours as inflammation resolves. Severe cases may require hourly dosing.

Approximately 1.5 hours (range 1-2 hours) for the ophthalmic suspension; terminal half-life in systemic circulation is about 3 hours after topical ocular administration.
2-3 hours (terminal) after IV administration; for topical ophthalmic use, systemic half-life is similar but local ocular half-life is prolonged due to corneal reservoir.
Primarily hepatic metabolism with minimal renal excretion (<5% unchanged in urine). Fecal elimination accounts for approximately 20% of the dose.
Primarily hepatic metabolism; renal excretion of inactive metabolites accounts for approximately 80% of elimination, with biliary/fecal elimination <20%.
