BROVANA vs THEOLAIR-SR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Theophylline is a methylxanthine that relaxes bronchial smooth muscle by inhibiting phosphodiesterase, increasing cAMP, and antagonizing adenosine receptors.
15 mcg (2 mL) by nebulization twice daily, not to exceed 30 mcg/day.
Oral: 300-600 mg every 12 hours; sustained-release formulation; adjust based on serum theophylline concentrations (target 5-15 mcg/mL).

Terminal elimination half-life: approximately 26 hours (range 22–30 hours) in healthy adults; prolonged in hepatic impairment (up to 50% increase).
Adults: 8 hours (range 5-12). Children: 3.5 hours (range 1-8). Smokers: 4-5 hours. Congestive heart failure/hepatic cirrhosis: >24 hours.
Primarily renal (60% unchanged drug); remainder via biliary/fecal (approximately 20%) and metabolic transformation.
Renal (10% unchanged) and hepatic metabolism (90%). Metabolites excreted in urine.
