AEROLATE III vs POLMON
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.
Polmon (polymyxin B) is a cationic polypeptide antibiotic that disrupts bacterial cell membrane integrity by binding to lipopolysaccharides and phospholipids in the outer membrane, increasing permeability and causing cell death.
Inhalation: 2 inhalations (200 mcg) twice daily, max 4 inhalations (400 mcg) per day. Oral: 4 mg twice daily, max 8 mg per day.
1-2 mg intravenously every 2-4 hours as needed; maximum 8 mg/day.

Terminal half-life 12-15 hours; clinically allows twice-daily dosing
Terminal elimination half-life is 12-18 hours in healthy adults; prolonged to 24-36 hours in severe hepatic impairment requiring dose adjustment.
Renal: 60% unchanged; biliary/fecal: 30% as metabolites; 10% other
Renal excretion of unchanged drug accounts for 40-50% of elimination; biliary/fecal excretion accounts for 50-60%.
