OXTRIPHYLLINE vs XOPENEX
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.
Selective beta-2 adrenergic receptor agonist that relaxes bronchial smooth muscle by increasing intracellular cyclic AMP levels.
200 mg orally every 6 hours, or 400 mg orally every 8-12 hours; maximum 600 mg per dose.
Nebulized solution: 0.63 mg or 1.25 mg 3 times daily every 6-8 hours; metered-dose inhaler: 2 inhalations (90 mcg per inhalation) 3 times daily every 6-8 hours.

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: 3.3-4.0 hours in adults. Clinically, twice-daily dosing is not recommended due to shorter half-life; every 4-6 hour dosing is standard for acute bronchodilation.
Renal: ~70-80% as unchanged drug and metabolites (including theophylline); biliary/fecal: minimal (<10%)
Renal: 80-100% as unchanged drug and metabolites (approximately 60% as unchanged levalbuterol, 20% as inactive sulfate conjugate). Fecal: <5%.
