AMINOPHYLLINE vs SLO-BID
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.
Relaxes smooth muscle of bronchial airways and pulmonary blood vessels by inhibiting phosphodiesterase, increasing intracellular cAMP, and promoting bronchodilation.
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.
Dose: 300-600 mg orally every 12 hours. Immediate-release: 5 mg/kg loading dose then 3 mg/kg every 6 hours. Extended-release: 10-15 mg/kg/day divided every 12 hours. Titrate to serum theophylline concentration of 5-15 mcg/mL.

Clinical Note
moderateAminophylline + Trovafloxacin
Adults: 7-9 hours (nonsmokers), 4-5 hours (smokers), 10-20 hours (neonates, hepatic impairment, CHF).
Terminal elimination half-life: 3-15 hours (mean ~10 hours in adults; 20-30 hours in neonates; 1-5 hours in smokers). Clinically, half-life decreases with smoking, increases with hepatic disease, heart failure, and certain drugs (e.g., cimetidine, ciprofloxacin).
Renal: ~10% unchanged; hepatic metabolism (N-demethylation, oxidation) accounts for >80% of elimination; <1% fecal.
Renal: 90% as metabolites (caffeine, theobromine, paraxanthine, and unchanged drug; 1,3-dimethyluric acid, 1-methyluric acid, and 3-methylxanthine). Biliary/fecal: <10%.
