OXTRIPHYLLINE vs THEOLIXIR
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.
Theophylline is a xanthine derivative that acts as a competitive nonselective phosphodiesterase inhibitor, increasing intracellular cyclic AMP levels, and as an antagonist at adenosine receptors (A1 and A2 subtypes), leading to bronchodilation, anti-inflammatory effects, and stimulation of respiratory drive.
200 mg orally every 6 hours, or 400 mg orally every 8-12 hours; maximum 600 mg per dose.
Oral: 200-400 mg every 6 hours (maximum 1600 mg/day) as sustained-release tablets or liquid. Inhalation: Not applicable.

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
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.
Terminal elimination half-life is 3–5 hours in adults (nonsmokers), but prolonged to 6–8 hours in neonates, elderly, and patients with hepatic cirrhosis or heart failure. Smoking (tobacco or marijuana) reduces half-life to 1–2 hours due to enzyme induction.
Renal: ~70-80% as unchanged drug and metabolites (including theophylline); biliary/fecal: minimal (<10%)
Renal excretion of unchanged drug accounts for approximately 10% of elimination; the remainder is hepatically metabolized, with 80% excreted in urine as metabolites (1-methyluric acid and 3-methylxanthine) and less than 10% in feces.
