BRONKODYL vs BRONKOMETER
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.
Beta-2 adrenergic receptor agonist; relaxes bronchial smooth muscle by increasing cyclic AMP.
Theophylline extended-release: 300-600 mg orally every 12 hours; target serum concentration 5-15 mcg/mL.
Isoetharine mesylate 0.5% solution: 2-4 inhalations every 4 hours as needed via hand-held nebulizer or IPPB.

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: 2-3 hours; clinically, bronchodilation persists but dosing interval is 3-4 hours due to rapid onset and offset.
Renal: approximately 90% as theophylline and its metabolites (1,3-dimethyluric acid, 3-methylxanthine, 1-methyluric acid); biliary/fecal: <10%.
Renal: 10-15% unchanged; 70-80% as sulfate conjugates; biliary/fecal: <5%.
