AMINOPHYLLINE vs PHYLLOCONTIN
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.
Sustained-release theophylline; nonselective phosphodiesterase (PDE) inhibitor, adenosine receptor antagonist, and histone deacetylase activator. Bronchodilation via relaxation of bronchial smooth muscle; also reduces airway hyperresponsiveness and inflammation.
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.
For chronic obstructive pulmonary disease and asthma: initial dose 225 mg orally twice daily; may increase to 450 mg twice daily. Based on theophylline, target serum concentration 5-15 mcg/mL.

Adults: 7-9 hours (nonsmokers), 4-5 hours (smokers), 10-20 hours (neonates, hepatic impairment, CHF).
Terminal elimination half-life: 3-8 hours in non-smoking adults; reduced to 1.5-5 hours in smokers; prolonged to 10-30 hours in heart failure or hepatic cirrhosis.
Renal: ~10% unchanged; hepatic metabolism (N-demethylation, oxidation) accounts for >80% of elimination; <1% fecal.
Renal: approximately 10% unchanged; hepatic metabolism accounts for ~90% of clearance; metabolites eliminated renally.
