Pharmacology:

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.

Indications:

Docopa (Doxophylline) is used to treat asthma, COPD and bronchospasm.

Dosage & Administration:

Adult: 400 mg (1 tablet) daily in the evening. However, in certain cases, 400 mg twice daily is recommended on the basis of the

clinical response. Doses as high as 1200 mg/day (400 mg 3 times daily) may also be prescribed. In elderly patients with

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

Children (above 6 years of age): The recommended dosage of Doxophylline is 6 mg/kg twice daily. The dose may be increased up to

18 mg/kg daily on the basis of clinical response.

Contrainidications:

Doxophylline is contraindicated in patients with acute myocardial infarction and hypotension. It is also contraindicated in

individuals who have shown hypersensitivity to its components.

Warning & Precautions:

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.

Side effects:

After administration occasionally nausea, vomiting, headache, etc. may occur

Drug interaction:

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 special groups:

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.

Store below 25°C and dry place, protect from light.
