BRONKODYL vs BROVANA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bronkodyl contains theophylline, a xanthine derivative. It acts as a bronchodilator by inhibiting phosphodiesterase, increasing cyclic AMP levels, leading to relaxation of bronchial smooth muscle. Additionally, it blocks adenosine receptors and may have anti-inflammatory effects.
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 extended-release: 300-600 mg orally every 12 hours; target serum concentration 5-15 mcg/mL.
15 mcg (2 mL) by nebulization twice daily, not to exceed 30 mcg/day.

Terminal elimination half-life is 3–8 hours in non-smoking adults, 1–5 hours in smokers, and 20–30 hours in premature neonates; clinical context: half-life increases in hepatic impairment, heart failure, and with certain medications (e.g., cimetidine, fluoroquinolones).
Terminal elimination half-life: approximately 26 hours (range 22–30 hours) in healthy adults; prolonged in hepatic impairment (up to 50% increase).
Renal: approximately 90% as theophylline and its metabolites (1,3-dimethyluric acid, 3-methylxanthine, 1-methyluric acid); biliary/fecal: <10%.
Primarily renal (60% unchanged drug); remainder via biliary/fecal (approximately 20%) and metabolic transformation.
