BROVANA vs CHOLEDYL SA
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.
Choledyl SA (theophylline, sustained-release) is a methylxanthine that inhibits phosphodiesterase, increasing intracellular cAMP, and blocks adenosine receptors, leading to bronchodilation and anti-inflammatory effects.
15 mcg (2 mL) by nebulization twice daily, not to exceed 30 mcg/day.
400 mg orally every 12 hours (sustained-release); maximum 800 mg every 12 hours.

Terminal elimination half-life: approximately 26 hours (range 22–30 hours) in healthy adults; prolonged in hepatic impairment (up to 50% increase).
Terminal elimination half-life: 7-9 hours in healthy adults; prolonged in hepatic cirrhosis (up to 30 hours), heart failure, COPD, and in neonates; shortened in smokers and cystic fibrosis.
Primarily renal (60% unchanged drug); remainder via biliary/fecal (approximately 20%) and metabolic transformation.
Renal: 90% as unchanged drug and metabolites (theophylline metabolites including 1,3-dimethyluric acid, 3-methylxanthine, and 1-methyluric acid). Biliary/fecal: <10%.
