OXTRIPHYLLINE vs POLMON
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Xanthine derivative that inhibits phosphodiesterase, increasing intracellular cyclic AMP; also antagonizes adenosine receptors, leading to bronchodilation and stimulation of respiratory drive.
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.
200 mg orally every 6 hours, or 400 mg orally every 8-12 hours; maximum 600 mg per dose.
1-2 mg intravenously every 2-4 hours as needed; maximum 8 mg/day.

Adults: 3-5 hours (non-smokers); smokers: 4-6 hours; children: 1-4 hours; neonates: 20-30 hours; congestive heart failure or hepatic cirrhosis: prolonged up to 10-20 hours. Note: Oxtriphylline is a choline salt of theophylline, and its half-life reflects theophylline kinetics.
Clinical Note
moderateOxtriphylline + Deferasirox
"The serum concentration of Deferasirox can be increased when it is combined with Oxtriphylline."
Clinical Note
moderateOxtriphylline + Acemetacin
"The therapeutic efficacy of Acemetacin can be decreased when used in combination with Oxtriphylline."
Clinical Note
moderateOxtriphylline + Tenofovir disoproxil
"The metabolism of Tenofovir disoproxil can be decreased when combined with Oxtriphylline."
Clinical Note
moderateOxtriphylline + Clotrimazole
Terminal elimination half-life is 12-18 hours in healthy adults; prolonged to 24-36 hours in severe hepatic impairment requiring dose adjustment.
Renal: ~70-80% as unchanged drug and metabolites (including theophylline); biliary/fecal: minimal (<10%)
Renal excretion of unchanged drug accounts for 40-50% of elimination; biliary/fecal excretion accounts for 50-60%.
