Duofylin
Duofylin Uses, Dosage, Side Effects, Food Interaction and all others data.
Duofylin is a metabolite of Bromhexine. It possesses mucokinetic (improvement in mucus transport) and secretolytic (liquefies secretions) properties. Duofylin stimulates the serous cells of the glands of the mucous membrane of bronchi, increasing the content of mucus secretion. The mucolytic effect is associated with depolymerization and splitting of mucoproteins and mucopolysaccharide fibres, which leads to reduction in the viscosity of mucus. Expectoration of mucus is facilitated and breathing is eased considerably. Duofylin stimulates production of phospholipids of surfactant by alveolar cells. Duofylin has anti-inflammatory properties. In patients with COPD, it improves airway patency. Beside these, Duofylin also exhibits anti-oxidant activity. Long-term use is possible because of the good tolerability of the preparation.

How Duofylin works
Duofylin is a mucolytic agent. Excessive Nitric oxide (NO) is associated with inflammatory and some other disturbances of airways function. NO enhances the activation of soluble guanylate cyclase and cGMP accumulation. Duofylin has been shown to inhibit the NO-dependent activation of soluble guanylate cyclase. It is also possible that the inhibition of NO-dependent activation of soluble guanylate cyclase can suppress the excessive mucus secretion, therefore it lowers the phlegm viscosity and improves the mucociliary transport of bronchial secretions.
Dosage
Duofylin dosage
Average daily dose (preferably after meal):Pediatric Drops:
- 0-6 months: 0.5 ml 2 times a day
- 6-12 months: 1 ml 2 times a day
- 1-2 years: 1.25 ml 2 times a day
Syrup:
- 2-5 years: 2.5 ml (1/2 teaspoonful) 2-3 times a day
- 5-10 years: 5 ml (1 teaspoonful) 2-3 times a day
- 10 years and adults: 10 ml (2 teaspoonful) 3 times a day.
Sustained release capsule:
- Adult and children over 12 years old: 1 capsule once daily
Specific application features: Duofylin may be prescribed to patients suffering from diabetes mellitus.
Side Effects
Gastrointestinal side-effects like epigastric pain, gastric fullness may occur occasionally. Rarely allergic responses such as eruption, urticaria or angioneurotic edema may occur.
Precaution
Duofylin should be given cautiously to patients with gastric and duodenal ulceration or convulsive disorders. Patients with hepatic and renal insufficiency should take it with caution.
Interaction
Duofylin has no interaction with cardioactive glycosides, corticosteroids, bronchodilators, diuretics and antibiotics (normally used in the treatment of bronchopulmonary affections). But Duofylin should not be taken simultaneously with antitussives (e.g. Codeine) because mucus, which has been liquefied by Duofylin, might not be expectorated.
Elimination Route
Rapid and almost complete.
Half Life
7-12 hours
Pregnancy & Breastfeeding use
Pregnancy: Teratogenic and fetal toxicity studies have shown no harmful effect of Duofylin. However, it is advised not to use during pregnancy, especially in the 1st trimester.
Lactation: Safety during lactation has not been established.
Contraindication
Contraindicated in known hypersensitivity to Duofylin or Bromhexine.
Interaction with other Medicine
Duofylin has no interaction with cardioactive glycosides, corticosteroids, bronchodilators, diuretics and antibiotics (normally used in the treatment of bronchopulmonary affections). But Duofylin should not be taken simultaneously with antitussives (e.g. Codeine) because mucus, which has been liquefied by Duofylin, might not be expectorated.

How safe is Duofylin?
Duofylin is a safe and well-tolerated treatment of bronchopulmonary diseases with a well-balanced and favorable benefit-risk profile.
How does Duofylin work?
Duofylin works by thinning down the mucus in the airway passages, thus making the mucus less sticky and it also facilitates the removal of the mucus from the airways.
