Contraindications
Doxophylline is contraindicated in individuals with known hypersensitivity to the drug or other xanthine derivatives. It is also contraindicated in patients with acute myocardial infarction, hypotension and during lactation.
Side Effects & Adverse Reactions
Patients treated with xanthine derivatives may suffer nausea, vomiting, epigastric pain, headache, irritability, insomnia, tachycardia, extrasystoles, tachypnea and in rare cases hyperglycemia or albuminuria. In case of overdose severe cardiac arrhythmias and tonic-clonic seizure may occur. These effects may represent the first signs of intoxication. The appearance of side effects may require discontinuation of the treatment which, if necessary, at the physician's discretion, may be resumed at lower doses after all signs and symptoms of toxicity have subsided.
Warnings & Precautions
Numerous factors may reduce the hepatic clearance of xanthine derivatives with increased plasma levels of the drug. These factors include age, congestive cardiac decompensation, chronic obstructive pulmonary disease, severe liver disease, concomitant infections, and the concurrent administration of several drugs such as: erythromycin, TAO, lincomycin, clindamycin, allopurinol, cimetidine, influenza vaccine and propanolol. In these cases, it may be necessary to reduce the dosage of the drug. In case of factors that may influence the clearance of xanthine derivatives, monitoring of the concentration of the blood levels of the drug is recommended for the control of the therapeutic range.
Caution should be taken in administering the product to patients with cardiac disease, hypertension, in the elderly, in patients with severe hypoxemia, hyperthyroidism, chronic corpulmonale, congestive heart failure, liver disease, peptic ulcer and in those with renal impairment. In particular, it is to be used with caution in patients with congestive heart failure, since the clearance of the drug is considerably slower in these patients in which high blood levels may persist for long periods even after discontinuation of the treatment. There is no risk of addiction or any other form of dependence.
Pharmacology & Mechanism of Action
Doxophylline is a novel bronchodilator. It structurally differs from Theophylline due to the presence of a dioxolane group in position 7. Doxophylline selectively inhibits phosphodiesterase 4 thereby relaxes bronchial smooth muscle. However, differently from Theophylline, Doxophylline appears to have decreased affinities toward adenosine A1 and A2 receptors, which may account for the better safety profile of the drug. Doxophylline is reported to inhibit platelet activating factor (PAF) and generation of leukotriene production.
