DULERA vs STIE-CORT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
DULERA is a combination of formoterol fumarate, a long-acting beta2-adrenergic agonist (LABA), and mometasone furoate, a corticosteroid. Formoterol acts by relaxing bronchial smooth muscle via beta2-receptor activation. Mometasone furoate reduces inflammation in the lungs by inhibiting inflammatory mediators and suppressing immune responses.
Glucocorticoid receptor agonist; modulates gene expression leading to anti-inflammatory and immunosuppressive effects.
Inhalation: 2 inhalations twice daily (morning and evening). Each inhalation delivers mometasone furoate 100/200 mcg and formoterol fumarate 5 mcg.
Topical: Apply a thin film to affected area twice daily. Maximum 2-week continuous use. In severe cases, apply up to 4 times daily. Do not exceed 50 g/week.

Formoterol: terminal half-life 10-14 hours (supports twice-daily dosing); Mometasone: terminal half-life 13.8 hours (range 10-20 hours) after inhalation.
Terminal elimination half-life is 1.5-2 hours (intravenous) and 2-3 hours (oral), reflecting rapid clearance; clinical context: supports twice-daily dosing for systemic effects.
Formoterol: 10-15% renal as unchanged drug and metabolites, remainder hepatically cleared; Mometasone: >99% biliary/fecal as metabolites, <1% renal unchanged.
Renal: 60-70% as metabolites; biliary/fecal: 20-30% as metabolites; unchanged drug: <5%.
