Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Theophylline is a xanthine derivative that acts as a bronchodilator by relaxing bronchial smooth muscle. Its mechanism may involve inhibition of phosphodiesterase, increasing cyclic AMP, and adenosine receptor antagonism.
Inhibits phosphodiesterase, increasing intracellular cAMP; causes bronchodilation, central nervous system stimulation, and positive inotropic/chronotropic effects.
1-2 inhalations (35-50 mcg/inhalation) twice daily via oral inhalation.
300 mg orally every 12 hours, extended-release tablet. Titrate to serum theophylline concentration of 5-15 mcg/mL.

Terminal elimination half-life: 3.5-4.5 hours. This short half-life supports twice-daily dosing in asthma management, with trough levels remaining above therapeutic threshold.
3-8 hours in adults; prolonged in neonates, cirrhosis, heart failure (up to 30 hours). Tobacco smoking induces clearance (half-life 4-5 hours).
Renal elimination: 60-70% as unchanged drug and metabolites. Biliary/fecal excretion: 20-30%.
Hepatic metabolism (90%), renal excretion of unchanged drug (10%). Metabolites excreted in urine.
