CHOLEDYL vs OXTRIPHYLLINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Choledyl is a salt of theophylline (1,3-dimethylxanthine) and choline. Theophylline acts as a bronchodilator by inhibiting phosphodiesterase (PDE) and antagonizing adenosine receptors, resulting in increased intracellular cAMP and smooth muscle relaxation. It also enhances respiratory drive and diaphragm contractility.
Xanthine derivative that inhibits phosphodiesterase, increasing intracellular cyclic AMP; also antagonizes adenosine receptors, leading to bronchodilation and stimulation of respiratory drive.
200-400 mg orally 4 times daily, not to exceed 2.4 g/day; or as sustained-release tablets: 400-600 mg twice daily.
200 mg orally every 6 hours, or 400 mg orally every 8-12 hours; maximum 600 mg per dose.

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: 7-9 hours (non-smoking adults); 4-5 hours (smokers); 20-30 hours (premature neonates, hepatic cirrhosis, CHF); clinical context: dose adjustment required for smokers and hepatic impairment.
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.
Primarily renal excretion of theophylline metabolites (1,3-dimethyluric acid, 3-methylxanthine, 1-methyluric acid), with 10% unchanged drug; biliary/fecal < 5%.
Renal: ~70-80% as unchanged drug and metabolites (including theophylline); biliary/fecal: minimal (<10%)
