- Description
Oxtriphylline is the choline salt form of theophylline. Once in the body, theophylline is released and acts as a phosphodiesterase inhibitor, adenosine receptor blocker, and histone deacetylase activator. Its main physiological reponse is to dilate the bronchioles. As such, oxytriphylline is indicated mainly for asthma, bronchospasm, and COPD (i.e. all the same indications as the other theophyllines). It is marketed under the name Choledyl SA, and several forms of oxytriphylline have been discontinued. In the US, oxtriphylline is no longer available.

Pharmacology
- Indication
Used to treat the symptoms of asthma, bronchitis, COPD, and emphysema.
- Associated Conditions
- Pharmacodynamics
Oxtriphylline is a bronchodilator. Oxtriphylline works in several ways: it relaxes muscles in your lungs and chest to allow more air in, decreases the sensitivity of your lungs to allergens and other substances that cause inflammation, and increases the contractions of your diaphragm to draw more air into the lungs.
- Mechanism of action
Oxtriphylline is a choline salt of theophylline. After ingestion, theophylline is released from oxytriphylline, and theophylline relaxes the smooth muscle of the bronchial airways and pulmonary blood vessels and reduces airway responsiveness to histamine, methacholine, adenosine, and allergen. Theophylline competitively inhibits type III and type IV phosphodiesterase (PDE), the enzyme responsible for breaking down cyclic AMP in smooth muscle cells, possibly resulting in bronchodilation. Theophylline also binds to the adenosine A2B receptor and blocks adenosine mediated bronchoconstriction. In inflammatory states, theophylline activates histone deacetylase to prevent transcription of inflammatory genes that require the acetylation of histones for transcription to begin.
Target Actions Organism AcGMP-inhibited 3',5'-cyclic phosphodiesterase A inhibitorHuman AcAMP-specific 3',5'-cyclic phosphodiesterase 4A inhibitorHuman AAdenosine receptor A2a antagonistHuman AAdenosine receptor A1 antagonistHuman AHistone deacetylase 2 activatorHuman - Absorption
After ingestion, theophylline is released from oxytriphylline in the acidic environment of the stomach.
- Volume of distribution
Theophylline has an apparent volume of distribution of 0.3–0.7 L/kg in children and adults, and the Vd is about twice that of an adult in premature infants.
- Protein binding
With a serum concentrations of 17 mcg/mL, adults and children have about 56% theophylline bound to plasma protein, and premature infants have about 36%.
- Metabolism
Theophylline undergoes hepatic metabolism to 1,3-dimethyluric acid, 1-methyluric acid, and 3-methylxanthine.
- Route of elimination
The kidneys are the main route of elimination for both theophylline and its metabolites, but some unchanged theophylline is eliminated in the feces.
- Half life
The serum half life varies greatly between patients and in age. The half life range for a healthy, nonsmoking adult is 3-12.8 hours, for children is 1.5–9.5 hours, and for for premature infants is 15–58 hours.
- Clearance
Theophylline has an average clearance in children (over 6 months) of 1.45 mL/kg per minute, and in healthy, nonsmoking adults of 0.65 mL/kg per hour.
- Toxicity
Symptoms of toxicity include abdominal pain (continuing or severe), confusion or change in behavior, convulsions (seizures), dark or bloody vomit, diarrhea, dizziness or lightheadedness, fast and/or irregular heartbeat, nervousness or restlessness (continuing), and trembling (continuing).
