AEROLATE III vs THEO-DUR
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.
Inhibits phosphodiesterase, increasing cAMP levels; antagonizes adenosine receptors; enhances contractility of skeletal and cardiac muscle, and relaxes bronchial smooth muscle.
Inhalation: 2 inhalations (200 mcg) twice daily, max 4 inhalations (400 mcg) per day. Oral: 4 mg twice daily, max 8 mg per day.
300-600 mg orally twice daily

Terminal half-life 12-15 hours; clinically allows twice-daily dosing
Terminal elimination half-life: 3-9 hours in adults (smokers: 4-5 hours; nonsmokers: 6-9 hours); 20-30 hours in premature neonates; 1-5 hours in children. Prolonged in hepatic cirrhosis, heart failure, and with CYP1A2 inhibitors.
Renal: 60% unchanged; biliary/fecal: 30% as metabolites; 10% other
Primarily hepatic metabolism by CYP1A2 and CYP3A4; renal excretion of unchanged drug accounts for approximately 10% in adults, up to 50% in neonates; biliary/fecal excretion negligible.
