BROVANA vs THEOCLEAR L.A.-260
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 causes bronchodilation by inhibiting phosphodiesterase, increasing cAMP levels, and antagonizing adenosine receptors.
15 mcg (2 mL) by nebulization twice daily, not to exceed 30 mcg/day.
Theophylline (THEOCLEAR L.A.-260) 260 mg orally every 12 hours. Adjust dose based on serum theophylline concentrations to achieve 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).
Terminal elimination half-life is approximately 6-12 hours in adults (range 3-12 hours, prolonged in congestive heart failure, liver disease, and with certain drugs). In neonates, half-life is prolonged (24-36 hours).
Primarily renal (60% unchanged drug); remainder via biliary/fecal (approximately 20%) and metabolic transformation.
Renal elimination of unchanged drug (10%) and hepatic metabolism (90%). Metabolism is primarily via CYP1A2 and CYP3A4, with metabolites excreted in urine (about 80% of the dose) and feces (about 20%).
