CORTENEMA vs DULERA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that binds to the glucocorticoid receptor, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, decrease cytokine production, and suppress inflammatory cell migration and activation in the colonic mucosa.
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.
One enema (100 mg hydrocortisone in 60 mL) administered rectally once daily, preferably at bedtime, for 21 days or until clinical response.
Inhalation: 2 inhalations twice daily (morning and evening). Each inhalation delivers mometasone furoate 100/200 mcg and formoterol fumarate 5 mcg.

1.8-3.5 hours (plasma); due to rectal administration and low systemic absorption, clinical effects persist longer than plasma levels suggest
Formoterol: terminal half-life 10-14 hours (supports twice-daily dosing); Mometasone: terminal half-life 13.8 hours (range 10-20 hours) after inhalation.
Primarily hepatic metabolism with renal excretion of inactive metabolites; <5% unchanged in urine; biliary/fecal elimination of metabolites accounts for ~80%
Formoterol: 10-15% renal as unchanged drug and metabolites, remainder hepatically cleared; Mometasone: >99% biliary/fecal as metabolites, <1% renal unchanged.
