OXTRIPHYLLINE vs THEOCLEAR L.A.-130
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, and blocks adenosine receptors, leading to bronchodilation and anti-inflammatory effects.
200 mg orally every 6 hours, or 400 mg orally every 8-12 hours; maximum 600 mg per dose.
130 mg orally every 12 hours; extended-release tablet.

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 3-8 hours in healthy adults (mean 5-6 hours). It is prolonged in patients with hepatic cirrhosis, heart failure, or COPD (up to 30 hours) and in neonates (20-30 hours). Smoking induces metabolism, reducing half-life to 1-4 hours.
Renal: ~70-80% as unchanged drug and metabolites (including theophylline); biliary/fecal: minimal (<10%)
Approximately 90% of theophylline is eliminated hepatically via CYP1A2 and CYP3A4 metabolism; renal excretion of unchanged drug accounts for about 10% in adults, but may increase to 50% in neonates. Biliary/fecal elimination is negligible.
