Doxofylline belongs to a group of medicines called bronchodilators. It is used to prevent and manage symptoms of asthma and COPD.
Doxofylline relaxes the airway muscles and widens the air passages in the lungs, making breathing easier. It also has cough-suppressing (antitussive) properties, which help reduce coughing.

Doxophylline is a newer-generation bronchodilator that differs structurally from theophylline due to the presence of a dioxolane group at position 7. This structural modification allows doxophylline to selectively inhibit phosphodiesterase-4 (PDE-4), resulting in relaxation of bronchial smooth muscle and improved airflow.
Unlike theophylline, doxophylline has lower affinity for adenosine A1 and A2 receptors, which contributes to its improved safety profile and reduced cardiovascular side effects. Additionally, doxophylline inhibits platelet-activating factor (PAF) and suppresses leukotriene production, further supporting its anti-inflammatory and bronchodilatory effects.

Elderly:
200 mg tablet, two or three times daily
Adults:
400 mg tablet, two or three times daily, or as directed by the physician
Children:
Above 12 years: 10 ml syrup or 200 mg tablet, two or three times daily
6–12 years: 6–9 mg/kg body weight, twice daily
Example: For a child weighing 10 kg, 3 ml (60 mg) twice daily
If the total daily requirement is 400 mg, a Doxophylline sustained-release (SR) tablet may be administered once daily, preferably as prescribed by the physician.
Drug-Drug Interaction: Doxofylline may interact with medicines used to treat gout (allopurinol), antacids (cimetidine), antibiotics (erythromycin, clindamycin, lincomycin), drugs used to lower high blood pressure (propranolol), central nervous system stimulants (ephedrine), flu vaccines (influenza vaccines), and anticonvulsants (phenytoin).
Drug-Food Interaction: Doxofylline may interact with caffeine. Therefore, avoid consuming Doxofylline with chocolate and caffeine-containing foods, such as cocoa beans and tea leaves, as they may increase the risk of severe side effects.
Drug-Disease Interaction: If you have low blood pressure, congestive heart failure, hypoxemia (low oxygen levels in the blood), hyperthyroidism (an overactive thyroid), pulmonary heart disease, stomach ulcers, kidney, liver, or heart disease, inform your doctor before taking Doxofylline.
Animal studies indicate that doxophylline does not adversely affect pre- or postnatal development. However, due to limited clinical data in pregnant women, use during pregnancy should be carefully considered based on the risk-benefit ratio.
The drug is contraindicated during lactation.
In cases of overdose, severe cardiac arrhythmias and tonic-clonic seizures may occur and may represent early signs of toxicity. If adverse effects appear, treatment may need to be discontinued and restarted at a lower dose after symptoms resolve, based on the physician's discretion.
If you are allergic to Brezofil SR 400 or any other medicines, please tell your doctor. You are recommended to avoid taking Doxofylline with chocolate and caffeinated foods, such as cocoa beans or tea leaves, as they may increase the risk of severe side effects. Doxofylline is contraindicated in breastfeeding mothers. If you are pregnant or planning a pregnancy, please consult a doctor before using Doxofylline. Do not take Doxofylline if you have low blood pressure or have had a heart attack. Brezofil SR 400 should be used with caution in congestive heart failure patients, as these patients have slow drug clearance, leading to high blood levels even after stopping treatment with Doxofylline. If you have low blood pressure, congestive heart failure, hypoxemia (low oxygen levels in the blood), hyperthyroidism (overactive thyroid), pulmonary heart diseases, stomach ulcer, kidney, liver, or heart diseases, inform your doctor before taking Doxofylline. Doxofylline is not recommended for children under 6 years of age, as its safety and efficacy have not been fully established.
Store in a dry place, protected from light and heat.
