Coscoril Uses, Dosage, Side Effects, Food Interaction and all others data.

Coscoril is a metabolite of Bromhexine. It possesses mucokinetic (improvement in mucus transport) and secretolytic (liquefies secretions) properties. Coscoril 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. Coscoril stimulates production of phospholipids of surfactant by alveolar cells. Coscoril has anti-inflammatory properties. In patients with COPD, it improves airway patency. Beside these, Coscoril also exhibits anti-oxidant activity. Long-term use is possible because of the good tolerability of the preparation.

How Coscoril works

Coscoril 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. Coscoril 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.


Coscoril 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

  • 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: Coscoril 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.


Coscoril 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.


Coscoril has no interaction with cardioactive glycosides, corticosteroids, bronchodilators, diuretics and antibiotics (normally used in the treatment of bronchopulmonary affections). But Coscoril should not be taken simultaneously with antitussives (e.g. Codeine) because mucus, which has been liquefied by Coscoril, 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 Coscoril. However, it is advised not to use during pregnancy, especially in the 1st trimester.
