Overview
DESCRIPTION Theophylline (Anhydrous) Extended-Release Tablets in a controlled-release system allows a 24-hour dosing interval for appropriate patients. Theophylline is structurally classified as a methylxanthine. It occurs as a white, odorless, crystalline powder with a bitter taste.
Uses
INDICATIONS AND USAGE Theophylline is indicated for the treatment of the symptoms and reversible airflow obstruction associated with chronic asthma and other chronic lung diseases, e.g., emphysema and chronic bronchitis.
Dosage
DOSAGE AND ADMINISTRATION Theophylline (Anhydrous) Extended-Release Tablets 400 or 600 mg can be taken once a day in the morning or evening. It is recommended that Theophylline (Anhydrous) Extended-Release Tablets be taken with meals. Patients should be advised that if they choose to take Theophylline (Anhydrous) Extended-Release Tablets with food it should be taken consistently with food and if they take it in a fasted condition it should routinely be taken fasted. It is important that the product whenever dosed be dosed consistently with or without food. Theophylline (Anhydrous) Extended-Release Tablets are not to be chewed or crushed because it may lead to a rapid release of theophylline with the potential for toxicity. The scored tablet may be split.
Side Effects
ADVERSE REACTIONS Adverse reactions associated with theophylline are generally mild when peak serum theophylline concentrations are 300 mg/day in adults and >12 mg/kg/day in children beyond >1 year of age). During the initiation of theophylline therapy, caffeine-like adverse effects may transiently alter patient behavior, especially in school age children, but this response rarely persists. Initiation of theophylline therapy at a low dose with subsequent slow titration to a predetermined age-related maximum dose will significantly reduce the frequency of these transient adverse effects (see DOSAGE AND ADMINISTRATION, Table V ). In a small percentage of patients (30 mcg/mL.
Interactions
Drug Interactions Theophylline interacts with a wide variety of drugs. The interaction may be pharmacodynamic, i.e., alterations in the therapeutic response to theophylline or another drug or occurrence of adverse effects without a change in serum theophylline concentration. More frequently, however, the interaction is pharmacokinetic, i.e., the rate of theophylline clearance is altered by another drug resulting in increased or decreased serum theophylline concentrations. Theophylline only rarely alters the pharmacokinetics of other drugs. The drugs listed in Table II have the potential to produce clinically significant pharmacodynamic or pharmacokinetic interactions with theophylline.
Warnings
WARNINGS Concurrent Illness Theophylline should be used with extreme caution in patients with the following clinical conditions due to the increased risk of exacerbation of the concurrent condition: Active peptic ulcer disease Seizure disorders Cardiac arrhythmias (not including bradyarrhythmias) Conditions That Reduce Theophylline Clearance There are several readily identifiable causes of reduced theophylline clearance. If the total daily dose is not appropriately reduced in the presence of these risk factors, severe and potentially fatal theophylline toxicity can occur . CONTRAINDICATIONS Theophylline (Anhydrous) Extended-Release Tablets are contraindicated in patients with a history of hypersensitivity to theophylline or other components in the product.
