Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits phosphodiesterase, increasing intracellular cAMP; causes bronchodilation, central nervous system stimulation, and positive inotropic/chronotropic effects.
Inhibits phosphodiesterase, increasing cAMP levels, leading to bronchodilation and reduced airway inflammation.
300 mg orally every 12 hours, extended-release tablet. Titrate to serum theophylline concentration of 5-15 mcg/mL.
Oral: 400-800 mg every 6-8 hours; extended-release formulation given every 12 hours. Target serum concentration 10-20 mcg/mL.

3-8 hours in adults; prolonged in neonates, cirrhosis, heart failure (up to 30 hours). Tobacco smoking induces clearance (half-life 4-5 hours).
3–8 hours in adults (mean ~5 h); prolonged in heart failure, liver disease, and COPD; decreased in smokers (4–5 h) and children.
Hepatic metabolism (90%), renal excretion of unchanged drug (10%). Metabolites excreted in urine.
Renal: approximately 10% unchanged; hepatic metabolism accounts for ~90% of elimination; metabolites excreted in urine.
