Expectolin
Expectolin Uses, Dosage, Side Effects, Food Interaction and all others data.
Expectolin is an oral mucolytic agent with a low level of associated toxicity. It acts on the mucus at the formative stages in the glands, within the mucus-secreting cells. Expectolin disrupts the structure of acid mucopolysaccharide fibres in mucoid sputum and produces less viscous mucus, which is easier to expectorate
Expectolin thins airway secretions, improving breathing and discomfort associated with thick mucus in airways associated with a variety of respiratory conditions.

Uses
Expectolinis used for the treatment of respiratory disorders associated with productive cough. These include; tracheobronchitis, bronchitis with emphysema, bronchiectasis, bronchitis with bronchospasm, chronic inflammatory pulmonary conditions and pneumoconiosis.
Expectolin is also used to associated treatment for these conditions: Bronchiectasis, Common Cold, Cough, Cough caused by Common Cold, Nasal Congestion, Whooping Cough, Airway secretion clearance therapy
How Expectolin works
Inflammation of the airways, increased mucus secretion, and altered mucociliary clearance are the hallmarks of various diseases of the respiratory tract. Mucus clearance is necessary for lung health; bromhexine aids in mucus clearance by reducing the viscosity of mucus and activating the ciliary epithelium, allowing secretions to be expelled from the respiratory tract.
Recent have studies have demonstrated that bromhexine inhibits the transmembrane serine protease 2 receptor (TMPRSS2) in humans. Activation of TMPRSS2 plays an important role in viral respiratory diseases such as influenza A and Middle East Respiratory Syndrome (MERS). Inhibition of receptor activation and viral entry by bromhexine may be effective in preventing or treating various respiratory illnesses, including COVID-19. In vitro studies have suggested the action of ambroxol (a metabolite of bromhexine) on the angiogensin-converting enzyme receptor 2 (ACE2), prevents entry of the viral envelope-anchored spike glycoprotein of SARS-Cov-2 into alveolar cells or increases the secretion of surfactant, preventing viral entry.
Dosage
Expectolin dosage
ExpectolinTablet:
Adults and children over 10 years: 8-16 mg 3 times daily. Children 5-10 years: 4 mg 3 times daily.
ExpectolinSyrup:
Adults: The recommended daily dose is 2 to 4 teaspoonful 3 times. Initially 4 teaspoonful 3 times daily and then as required.
Children: Suggested dosage for children under 2 years is 1/4 teaspoonful 3 times daily, for 2-5 years 1/2 teaspoonful 3 times daily and for children aged 5-10 years 1 teaspoonful 3 times daily.
Side Effects
Gastrointestinal side-effects may occur occasionally with Expectolin and a transient rise in serum aminotransferase values has been reported. Other reported adverse effects include headache, dizziness, sweating and skin rash.
Toxicity
The oral LD50 of bromhexine in rats is 6 g/kg. The observed symptoms of accidental overdose with bromhexine are consistent with the known adverse effects of bromhexine, including headache, nausea, and vomiting, among other symptoms. Provide symptomatic treatment and contact poison control services if an overdose is confirmed or suspected.
Precaution
Since mucolytics may disrupt the gastric mucosa so Expectolin should be used with care in patients with a history of peptic ulceration.
Food Interaction
No interactions found.Volume of Distribution
After intravenous administration in a pharmacokinetic study, bromhexine was found to be widely distributed. Expectolin is known to cross the blood-brain barrier; small concentrations may cross the placenta. The average volume of distribution of bromhexine was 1209 ± 206 L (19 L/kg). Lung tissue concentrations of bromhexine two hours after a dose were 1.5 to 3.2 times higher in bronchial tissues than plasma concentrations. Pulmonary parynchema concentrations were 3.4 to 5.9 times higher when compared to plasma concentrations.
Elimination Route
After oral administration, bromhexine demonstrates linear pharmacokinetics when given in doses of 8-32 mg. Expectolin is readily absorbed in the gastrointestinal tract at a rapid rate. This drug undergoes extensive first-pass effect in the range of 75-80%. The bioavailability is therefore reduced to approximately 22-27%.
Half Life
Following single oral doses ranging from 8 and 32 mg, the terminal half-life of bromhexine has been measured between 6.6 and 31.4 hours.
Clearance
The clearance of bromhexine ranges from 843-1073 mL/min, within the range of the hepatic circulation.
Elimination Route
After a dose of bromhexine was administered during a pharmacokinetic study, approximately 97% of the radiolabeled dose was detected in the urine; under 1% was detected as the parent drug.
Pregnancy & Breastfeeding use
Pregnancy Category B. Expectolin has been taken by a large number of pregnant women and women of child bearing age without any proven increase in the frequency of malformations or other direct or indirect harmful effects on the fetus having been observed.
It is not known whether bromhexine is excreted in breast milk or whether it has a harmful effect on the breastfeeding infant. Therefore it is not recommended for breast feeding mothers unless the potential benefits to the patient are weighed against the possible risk to the infant.
Contraindication
Contraindicated to those who are hypersensitive to Expectolin Hydrochloride.
Storage Condition
Store below 25° C. Protect from light. Keep the container tightly closed.

FAQ
What is Expectolin used for?
Expectolin is a mucolytic drug used in the treatment of respiratory disorders associated with viscid or excessive mucus. It is used to relieve chest congestion. Expectolin is used in a condition where there is a lot of thick phlegm in the airways. As a mucolytic, it helps to relieve productive cough by thinning the phlegm in the airways and facilitating the removal of the mucus.
How safe is Expectolin?
Expectolin should be used with caution in patients who have a history of gastric ulcers. Expectolin improves mucus transport by lowering mucus viscosity and stimulating the ciliated epithelial layer.
How does Expectolin work?
Expectolin works by blocking a certain natural substance (known as histamine) that your body makes during an allergic reaction.
What are the common side effects of Expectolin?
Common side effects include bloatedness, diarrhea, dizziness, headache, indigestion, nausea, sweating and skin rashes.
