DULERA vs FLORONE
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; induces phospholipase A2 inhibitory proteins (lipocortins), which suppress release of arachidonic acid and subsequent prostaglandin/leukotriene synthesis; also suppresses cytokine production and immune cell migration.
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 layer to affected skin once or twice daily. Maximum use: 45 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 of approximately 2-3 hours; clinical context: duration of action may extend beyond half-life due to tissue binding.
Formoterol: 10-15% renal as unchanged drug and metabolites, remainder hepatically cleared; Mometasone: >99% biliary/fecal as metabolites, <1% renal unchanged.
Renal (approximately 80% as metabolites, <5% unchanged), biliary/fecal (remainder).
