AEROLATE III vs THEOPHYL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
AEROLATE III (theophylline) is a bronchodilator that inhibits phosphodiesterase, increasing intracellular cAMP levels, leading to relaxation of bronchial smooth muscle and suppression of airway inflammation.
Theophylline is a methylxanthine that causes bronchodilation primarily through inhibition of phosphodiesterase (PDE) and antagonism of adenosine receptors. It also has mild anti-inflammatory effects and enhances mucociliary clearance.
Inhalation: 2 inhalations (200 mcg) twice daily, max 4 inhalations (400 mcg) per day. Oral: 4 mg twice daily, max 8 mg per day.
300 mg orally every 6 hours or 400-600 mg extended-release orally every 12-24 hours; intravenous loading dose 5-6 mg/kg over 20-30 minutes, then continuous infusion 0.4-0.6 mg/kg/h

Terminal half-life 12-15 hours; clinically allows twice-daily dosing
Terminal elimination half-life: Adults nonsmokers: 6–12 h (mean 8.7 h); adult smokers: 4–5 h; children: 3–5 h; neonates: 20–30 h; hepatic cirrhosis: up to 30 h. Half-life increases with congestive heart failure, fever, and concurrent CYP1A2 inhibitors (e.g., cimetidine, fluvoxamine).
Renal: 60% unchanged; biliary/fecal: 30% as metabolites; 10% other
Renal: 10% unchanged in adults (higher in neonates). Hepatic metabolism to inactive metabolites (1,3-dimethyluric acid, 3-methylxanthine, 1-methyluric acid) excreted renally; fecal excretion <5%.
