Introduction
Bromhexine Hydrochloride is a mucolytic agent used to break down and thin mucus in the respiratory tract, making it easier to expel. It is commonly used in the treatment of respiratory conditions where excessive mucus production occurs, such as chronic bronchitis, asthma, and chronic obstructive pulmonary disease (COPD). It is available in oral forms such as tablets, syrups, and drops, and is widely used for both adults and children.
Uses
Bromhexine Hydrochloride is primarily used for the following conditions:
- Chronic bronchitis
- Asthma with thick mucus secretions
- Chronic obstructive pulmonary disease (COPD)
- Other respiratory disorders characterized by excessive or thickened mucus production

Mechanism of Action
Bromhexine Hydrochloride acts by breaking down mucopolysaccharide fibers in the mucus, reducing its viscosity and making it less sticky. It promotes the production of a less viscous mucus, facilitating easier coughing up of secretions and improving breathing in patients with congested airways. Bromhexine is also believed to stimulate the production of surfactant in the lungs, which further aids in respiratory efficiency.
How Long Does It Take to Work?
Improvement in mucus clearance can be observed within 1 to 2 days of starting Bromhexine Hydrochloride treatment. However, for significant relief in symptoms, it may take up to 4 to 5 days, depending on the severity of the condition and dosage regimen.
Absorption
Bromhexine Hydrochloride is rapidly absorbed after oral administration, with bioavailability ranging from 20% to 80%, due to first-pass metabolism in the liver. Peak plasma concentrations are typically reached within 1 to 2 hours after ingestion.
Route of Elimination
Approximately 85% of Bromhexine is eliminated through the kidneys in the form of metabolites, with very little of the unchanged drug excreted in the urine. The remainder is excreted in the bile and feces.
Dosage
The recommended doses for adults and children are stated below:- Adult & Children over 12 years: 10 ml (2 teaspoons) 3 times daily
- Children 6-12 years: 5 ml (1 teaspoon) 3 times daily
- Children 2-6 years: 2.5 ml (1/2 teaspoon) 3 times daily
- Bromhexine Hydrochloride is not recommended for children under 2 years of age without advice.
Typical dosages for Bromhexine Hydrochloride are:
- Adults: 8 to 16 mg taken 3 times daily.
- Children (6-12 years): 4 to 8 mg taken 2 to 3 times daily.
- Children (2-6 years): 2 mg taken 2 to 3 times daily.
The dosage may be adjusted by healthcare providers depending on the severity of symptoms and the patient's response to the medication.
Administration
Bromhexine Hydrochloride is administered orally, usually as a tablet, syrup, or oral drops. It should be taken with plenty of fluids to assist in thinning mucus. Tablets should be swallowed whole, while syrup and drops can be measured according to the prescribed dose.
Side Effects
Common side effects include:
- Nausea
- Vomiting
- Diarrhea
- Stomach discomfort
- Skin rash (in rare cases)
Severe side effects are rare but may include allergic reactions, such as swelling of the face or throat and difficulty breathing. If any serious reactions occur, medical attention should be sought immediately.
Toxicity
At therapeutic doses, Bromhexine Hydrochloride has low toxicity. In case of an overdose, symptoms may include gastrointestinal disturbances, such as nausea, vomiting, or diarrhea. Treatment typically involves supportive care and symptomatic treatment, such as fluid replacement and activated charcoal if indicated.
Precautions
Caution should be exercised when prescribing Bromhexine Hydrochloride to patients with a history of gastric ulcers or severe hepatic or renal impairment. In such cases, dose adjustments may be necessary.
Interaction
Drug Interactions
Bromhexine may interact with certain antibiotics, such as erythromycin, amoxicillin, or cefuroxime, potentially increasing the concentration of these drugs in bronchial secretions. This interaction can be beneficial in respiratory infections. There are no significant interactions with other medications; however, care should be taken when combining with other expectorants or antitussive medications.
Food Interactions
Bromhexine can be taken with or without food. However, taking it with food may reduce gastrointestinal discomfort.
Disease Interactions
Use with caution in patients with peptic ulcer disease or severe liver or kidney impairment. The drug should be monitored closely in such cases to avoid adverse effects.
Pregnancy Use
There is limited data on the use of Bromhexine Hydrochloride during pregnancy. Animal studies have not demonstrated significant teratogenic effects, but human studies are lacking. Bromhexine should only be used in pregnancy if clearly needed and under medical supervision.
Lactation Use
It is not known whether Bromhexine Hydrochloride is excreted in human breast milk. Therefore, caution should be exercised when administering this medication to breastfeeding women. Consultation with a healthcare provider is recommended.
Acute Overdose
An overdose of Bromhexine Hydrochloride may result in gastrointestinal symptoms, such as nausea, vomiting, and diarrhea. Treatment involves symptomatic and supportive care, including the administration of activated charcoal to prevent further absorption in cases of significant overdose. Fluid replacement therapy may also be required.
Contraindication
Bromhexine Hydrochloride is contraindicated in patients with known hypersensitivity or allergy to the drug or any of its components. It should also not be used in patients with a history of peptic ulcers unless carefully monitored by a healthcare provider.
Use Direction
Bromhexine should be taken as directed by the healthcare provider. For optimal results, the medication should be taken with plenty of fluids, and dosing should be followed consistently for the full duration of treatment to ensure the breakdown of mucus and clearance from the respiratory system. Do not exceed the prescribed dose.
Storage Conditions
Bromhexine Hydrochloride should be stored at room temperature (15°C to 30°C), away from light and moisture. Keep out of reach of children. Ensure that syrups or drops are tightly closed when not in use to prevent contamination.
Volume of Distribution
The volume of distribution of Bromhexine is approximately 7.5 L/kg, indicating that the drug is widely distributed into tissues, including lung tissue where it exerts its mucolytic effects.
Half-Life
The plasma half-life of Bromhexine Hydrochloride is about 12 hours. The drug undergoes extensive metabolism in the liver, and its metabolites are excreted mainly via the kidneys.
Clearance
The clearance of Bromhexine Hydrochloride occurs primarily through renal excretion, with most of the drug eliminated as metabolites. A smaller portion is excreted through the feces. Patients with renal or hepatic impairment may have reduced clearance and may require dose adjustments.
