DULERA vs PEDIAPRED
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.
Prednisolone is a glucocorticoid receptor agonist that binds to the intracellular glucocorticoid receptor, leading to modulation of gene expression. It suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and decreasing cytokine production (e.g., IL-1, IL-6, TNF-alpha). It also suppresses immune responses by reducing lymphocyte proliferation and activity.
Inhalation: 2 inhalations twice daily (morning and evening). Each inhalation delivers mometasone furoate 100/200 mcg and formoterol fumarate 5 mcg.
Oral: 5-60 mg/day as a single dose or divided doses; adjust based on condition and response.

Formoterol: terminal half-life 10-14 hours (supports twice-daily dosing); Mometasone: terminal half-life 13.8 hours (range 10-20 hours) after inhalation.
2.5–3.5 hours (terminal) in children; clinical context: requires multiple daily doses for sustained effect.
Formoterol: 10-15% renal as unchanged drug and metabolites, remainder hepatically cleared; Mometasone: >99% biliary/fecal as metabolites, <1% renal unchanged.
Renal: ~80% as metabolites (mainly glucuronides and sulfates) and <5% unchanged; fecal: ~15%.
