DILOR vs OXTRIPHYLLINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
DILOR (dyphylline) is a xanthine bronchodilator that inhibits phosphodiesterase, increasing intracellular cAMP levels, leading to relaxation of bronchial smooth muscle and suppression of airway responsiveness to stimuli. It also exhibits anti-inflammatory effects and enhances mucociliary clearance. Unlike theophylline, dyphylline is not converted to theophylline in vivo.
Xanthine derivative that inhibits phosphodiesterase, increasing intracellular cyclic AMP; also antagonizes adenosine receptors, leading to bronchodilation and stimulation of respiratory drive.
DILOR (Dyphylline) 200-400 mg orally every 6 hours; maximum 1.6 g/day. Also available as IM injection: 250-500 mg every 6 hours.
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 is 3-4 hours in adults; may be prolonged in neonates, elderly, and patients with hepatic or cardiac dysfunction. Theophylline is a narrow therapeutic index drug; half-life dictates dosing frequency and need for therapeutic drug monitoring.
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.
Renal: approximately 50% unchanged drug; biliary/fecal: minimal (less than 10%). The remainder undergoes hepatic metabolism.
Renal: ~70-80% as unchanged drug and metabolites (including theophylline); biliary/fecal: minimal (<10%)
