AEROLATE SR vs BROVANA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
AEROLATE SR is a sustained-release formulation of theophylline, a methylxanthine bronchodilator. It acts by inhibiting phosphodiesterase (PDE) isoenzymes, leading to increased intracellular cyclic AMP (cAMP) levels. This results in relaxation of bronchial smooth muscle and suppression of the response of airways to stimuli. Theophylline also has anti-inflammatory effects, including inhibition of late-phase allergen-induced responses and reduction of eosinophil infiltration.
BROVANA (arformoterol tartrate) is a long-acting beta2-adrenergic agonist (LABA). It stimulates intracellular adenyl cyclase, increasing cyclic AMP levels, leading to relaxation of bronchial smooth muscle and inhibition of mast cell mediator release.
400-800 mcg inhaled twice daily. For acute bronchospasm, 200-400 mcg as needed.
15 mcg (2 mL) by nebulization twice daily, not to exceed 30 mcg/day.

Terminal elimination half-life 12 hours (range 10–15 h) in adults; prolonged in hepatic impairment (up to 24 h) and elderly.
Terminal elimination half-life: approximately 26 hours (range 22–30 hours) in healthy adults; prolonged in hepatic impairment (up to 50% increase).
Renal: 60% as unchanged drug; biliary/fecal: 30% as metabolites; 10% as unchanged in feces.
Primarily renal (60% unchanged drug); remainder via biliary/fecal (approximately 20%) and metabolic transformation.
