Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Theophylline competitively inhibits phosphodiesterase, increasing cAMP levels, and acts as an adenosine receptor antagonist, leading to bronchodilation and reduced airway inflammation.
Theophylline is a methylxanthine that inhibits phosphodiesterase, increasing intracellular cAMP levels, leading to bronchodilation. It also acts as an adenosine receptor antagonist and may enhance diaphragmatic contractility.
For asthma and COPD: 1-2 inhalations (90 mcg each) via metered-dose inhaler, 2 puffs twice daily, maximum 4 puffs twice daily. For acute exacerbations: 4-8 puffs every 20 minutes for up to 4 hours, then every 1-4 hours as needed.
Theophylline 200 mg orally every 6 hours (extended-release) or as directed by serum theophylline concentrations. Usual adult target: 400-600 mg/day.

Terminal elimination half-life 12 hours; clinical context: q12h dosing achieves steady-state in 2-3 days
Terminal elimination half-life: ~8 hours (range 3–12 hours) in adults; prolonged in hepatic impairment, heart failure, COPD, and neonates. Significantly shorter in smokers (4–6 hours).
Renal (80% as unchanged drug), biliary/fecal (15% as metabolites), 5% other
Renal: ~10% unchanged; Hepatic metabolism (CYP1A2, CYP3A4) accounts for ~90% of elimination; metabolites (caffeine, 3-methylxanthine, 1-methyluric acid) excreted renally. Fecal excretion negligible.
