Doxophylline is a new generation xanthine derivative which has a dioxolane group at N-7 position of its chemical structure. Doxophylline inhibits phosphodiesterase activities. Moreover, Doxophylline appears to have a less affinity towards adenosine A1 and A2 receptors which is account for the better safety profile of the drug. Doxophylline also inhibits platelet activating factor and the generation of leukotrienes.

In elderly patients with concomitant cardiovascular, hepatic and renal diseases recommended dosage should be 200 mg twice daily.

Doxophylline is contraindicated in patients with acute myocardial infarction and hypotension. It is also contraindicated in individuals who have shown hypersensitivity to its components.
The half-life of xanthine derivative is influenced by a number of variables. It may be prolonged in patients with liver disease, congestive heart failure and in those patients taking certain other drugs (erythromycin, troleandomycin, lincomycin, allopurinol, cimetidine, propranolol and anti-flu vaccine). In these cases, a lower dose of Doxophylline may be needed. Phenytoin and other anticonvulsants may cause shorter mean half-life and in these cases higher doses of Doxophylline may be needed.
After administration occasionally nausea, vomiting, headache, etc. may occur.
Doxophylline should not be administered together with other xanthine derivatives. Toxic synergism with ephedrine has been documented for xanthines. Like other xanthines, concomitant therapy with erythromycin, troleandomycin, lincomycin, allopurinol, cimetidine, ranitidine, propranolol and anti-flu vaccine may decrease the hepatic clearance of xanthines causing an increase in blood levels.
Use in pregnancy: Animal reproduction studies indicate that Doxophylline does not cause fetal harm when administered to pregnant animals nor can affect reproduction capacity. However, since there is limited experience in human during pregnancy, Doxophylline should be given to pregnant women only if clearly needed.
Use in nursing mothers: Doxophylline is contraindicated in nursing mothers.
