FLOVENT HFA vs TRIESENCE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fluticasone propionate is a synthetic corticosteroid that binds to glucocorticoid receptors, increasing the synthesis of lipocortins, which inhibit phospholipase A2, thereby reducing arachidonic acid release and decreasing prostaglandin and leukotriene production. It also suppresses inflammatory cell migration and cytokine release, leading to reduced airway inflammation and hyperreactivity.
Corticosteroid that suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating cytokine production.
Adult: 88-880 mcg twice daily via oral inhalation; typical starting dose: 88 mcg twice daily for patients previously on bronchodilators alone, 220 mcg twice daily for patients on inhaled corticosteroids.
1 to 4 mg (0.025 to 0.1 mL of 40 mg/mL suspension) intravitreal injection once.

Terminal elimination half-life is approximately 7.8 hours (range 6.5-10.6 hours) after inhalation, supporting twice-daily dosing.
Approximately 3.3 hours for triamcinolone acetonide; with intravitreal administration, detectable levels persist for weeks to months.
Primarily fecal (approximately 60-80%) after biliary elimination, with renal excretion accounting for <5% as unchanged drug and metabolites.
Primarily hepatic metabolism; renal excretion of metabolites (<5% unchanged). Biliary/fecal elimination accounts for minimal clearance.
