OXTRIPHYLLINE vs THEOCLEAR-200
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 methylxanthine that inhibits phosphodiesterase, increasing intracellular cAMP levels, leading to bronchodilation. It also acts as an adenosine receptor antagonist and may enhance diaphragmatic contractility.
200 mg orally every 6 hours, or 400 mg orally every 8-12 hours; maximum 600 mg per dose.
Theophylline 200 mg orally every 6 hours (extended-release) or as directed by serum theophylline concentrations. Usual adult target: 400-600 mg/day.

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: ~8 hours (range 3–12 hours) in adults; prolonged in hepatic impairment, heart failure, COPD, and neonates. Significantly shorter in smokers (4–6 hours).
Renal: ~70-80% as unchanged drug and metabolites (including theophylline); biliary/fecal: minimal (<10%)
Renal: ~10% unchanged; Hepatic metabolism (CYP1A2, CYP3A4) accounts for ~90% of elimination; metabolites (caffeine, 3-methylxanthine, 1-methyluric acid) excreted renally. Fecal excretion negligible.
