Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminophylline is a bronchodilator and respiratory stimulator that acts as a non-selective phosphodiesterase inhibitor, increasing cyclic AMP levels, and as an adenosine receptor antagonist. It also enhances diaphragmatic contractility and mucociliary clearance.
Aminophylline is a salt form of theophylline that exerts bronchodilation by inhibiting phosphodiesterase, increasing intracellular cAMP. It also blocks adenosine receptors, stimulates central respiratory drive, and reduces diaphragmatic fatigue.
Loading dose: 5-6 mg/kg IV over 20-30 minutes (if no recent theophylline). Maintenance: 0.4-0.6 mg/kg/hour IV continuous infusion; oral: 300-600 mg/day divided every 6-8 hours.
Loading dose: 6 mg/kg IV over 30 minutes (use ideal body weight). Maintenance: 0.5-0.7 mg/kg/hour IV infusion for non-smoking adults; 0.8-1.0 mg/kg/hour for smokers. Oral: 200-400 mg every 6-8 hours (extended-release formulations available).

Adults: 7-9 hours (nonsmokers), 4-5 hours (smokers), 10-20 hours (neonates, hepatic impairment, CHF).
Terminal elimination half-life is approximately 7-9 hours in healthy adults. In smokers, half-life decreases to 4-5 hours. In patients with hepatic cirrhosis, heart failure, or COPD, half-life may prolong to 20-30 hours.
Renal: ~10% unchanged; hepatic metabolism (N-demethylation, oxidation) accounts for >80% of elimination; <1% fecal.
Primarily hepatic metabolism (approximately 90%) to 1,3-dimethyluric acid and other metabolites; renal excretion of unchanged drug accounts for about 10-13% of the dose. Less than 1% is excreted via bile or feces.
