ARMONAIR RESPICLICK vs SYMBICORT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Armonair Respiclick is a metered-dose inhaler containing beclomethasone dipropionate, a corticosteroid. It exerts anti-inflammatory effects by binding to glucocorticoid receptors, inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppressing inflammatory cell migration and cytokine release in the airways.
Symbicort is a combination product containing budesonide, a corticosteroid, and formoterol fumarate dihydrate, a long-acting beta2-adrenergic agonist (LABA). Budesonide reduces inflammation by inhibiting inflammatory mediators and suppressing airway hyperresponsiveness. Formoterol stimulates beta2-adrenergic receptors in bronchial smooth muscle, leading to bronchodilation via increased cyclic AMP. The combination provides anti-inflammatory and bronchodilatory effects.
Inhaled: 55 mcg to 113 mcg per actuation, 1 to 2 actuations twice daily. Maximum 2 actuations twice daily.
1-2 inhalations (80/4.5 mcg or 160/4.5 mcg) twice daily; maximum 2 inhalations twice daily of 160/4.5 mcg.

Terminal elimination half-life is approximately 26 hours (range 21-36 hours). This supports once-daily dosing for bronchodilation in COPD.
Budesonide: 2–3 hours (terminal); Formoterol: 10 hours (terminal). Clinical context: Twice-daily dosing maintains bronchodilation.
Renal: approximately 99% of an administered dose is excreted in urine, with 95% as conjugated metabolites and 2% as free arformoterol. Fecal: approximately 1%. Biliary: negligible.
Budesonide: 60% renal (as metabolites), 40% fecal; Formoterol: 60% renal (as metabolites), 40% fecal.
