Doxofylline (400mg)

Respiratory disorders such as asthma, chronic obstructive pulmonary disease (COPD), chronic bronchitis, and other obstructive airway diseases are a major health burden in India. Factors like pollution, smoking, occupational exposure, and recurrent respiratory infections contribute significantly to the rising prevalence of these conditions. Breathlessness, wheezing, chest tightness, and persistent cough can severely affect daily life and productivity.

Modern respiratory management focuses on medicines that not only relieve symptoms but also improve lung function with minimal side effects. DX PHYLLIN 400, containing Doxofylline 400 mg, is one such advanced bronchodilator widely prescribed for long-term respiratory care. It is known for its effective airway-relaxing action with a better safety profile compared to traditional methylxanthines.

What is DX PHYLLIN 400?

DX PHYLLIN 400 is an oral bronchodilator tablet that contains Doxofylline 400 mg. Doxofylline belongs to the xanthine derivative group and is structurally related to theophylline but with significant pharmacological advantages.

Composition of DX PHYLLIN 400

• Active Ingredient: Doxofylline 400 mg

• Dosage Form: Oral tablet

DX PHYLLIN 400 is commonly prescribed for patients who require long-term bronchodilation with improved tolerability and reduced cardiovascular and gastric side effects.

How DX PHYLLIN 400 Works (Mechanism of Action)

Doxofylline works by relaxing the smooth muscles of the airways, allowing easier airflow to the lungs.

Mechanism Explained Simply

• Doxofylline inhibits phosphodiesterase (PDE) enzymes, leading to increased cyclic AMP levels

• This results in bronchial smooth muscle relaxation

• Airways widen, reducing resistance to airflow

• Breathing becomes easier, and symptoms like wheezing and breathlessness improve

Why Doxofylline is Different

Unlike theophylline:

• It has minimal effect on adenosine receptors, reducing heart-related side effects

• Lower risk of gastric irritation

• Better safety margin, especially for long-term use

This makes DX PHYLLIN 400 a preferred option for chronic respiratory diseases.
