Usage
This combination medication is primarily prescribed for respiratory conditions like:
- Asthma: A chronic respiratory disease characterized by inflammation and narrowing of the airways, leading to wheezing, shortness of breath, chest tightness, and coughing.
- Chronic Obstructive Pulmonary Disease (COPD): A progressive lung disease characterized by airflow limitation that interferes with normal breathing.
- Bronchitis: Inflammation of the bronchial tubes, which carry air to and from the lungs.
- Bronchospasm: Sudden constriction of the muscles in the walls of the bronchioles.
Pharmacological Classification:
- Bromhexine: Mucolytic, Expectorant
- Choline Theophyllinate: Bronchodilator, Xanthine derivative
- Salbutamol: Bronchodilator, Beta2-adrenergic agonist
Mechanism of Action:
This combination works synergistically to improve respiratory function:
- Bromhexine: Breaks down mucus, making it less viscous and easier to cough up.
- Choline Theophyllinate: Relaxes the smooth muscles of the airways, widening the bronchi and improving airflow.
- Salbutamol: Relaxes the bronchial smooth muscle, providing quick relief from bronchospasm.
Alternate Names
This combination doesn’t have a specific international nonproprietary name (INN). It is typically identified by the names of its components.
Brand Names: Durasalyn, Asthatif, Ventirex Plus, Xputum (and possibly others depending on the region).
How It Works
Pharmacodynamics:
- Bromhexine: Decreases mucus viscosity by breaking disulfide bonds in mucoproteins. It may also stimulate serous cells in the bronchial mucosa, producing less viscous secretions.
- Choline Theophyllinate: Inhibits phosphodiesterase, increasing intracellular cAMP levels, leading to smooth muscle relaxation and bronchodilation. It also has some mild anti-inflammatory and diuretic effects.
- Salbutamol: Selectively stimulates beta2-adrenergic receptors in the lungs, activating adenylate cyclase and increasing cAMP, leading to bronchodilation.
Pharmacokinetics:
- Absorption: All three components are absorbed orally.
- Metabolism: Salbutamol is primarily metabolized in the liver. Choline theophyllinate is metabolized in the liver, and its elimination is influenced by liver function and potential drug interactions. Bromhexine is also metabolized in the liver.
- Elimination: Metabolites of all three drugs are primarily excreted in the urine.
Dosage
Dosage is determined by the patient’s age, weight, the severity of their condition, and the specific product formulation. Always adhere to the prescribing physician’s instructions.
Standard Dosage
Adults:
- Syrup/Liquid: Dosage varies depending on the specific formulation. A common dosage could be 5-10 ml three or four times daily.
- Tablets/Capsules: Dosages vary. Refer to the specific product information.
Children:
- Dosage is weight-based and should be carefully determined by a pediatrician. Pediatric formulations are typically available as syrups or liquids.
- Refer to pediatric guidelines for precise dosing.
Special Cases:
- Elderly Patients: Start with a lower dose and monitor closely for side effects. Dose adjustments may be needed due to age-related decline in organ function.
- Patients with Renal Impairment: Caution is advised; dose adjustment may be necessary.
- Patients with Hepatic Dysfunction: Choline theophyllinate clearance is reduced in hepatic impairment, so dosage adjustment is essential. Monitor closely for adverse effects.
- Patients with Comorbid Conditions: Caution is necessary in patients with cardiovascular disease, hypertension, diabetes, hyperthyroidism, or peptic ulcers.
Clinical Use Cases
This combination is not typically indicated for specific clinical settings like intubation, surgical procedures, mechanical ventilation, or ICU use. Its primary use is in the outpatient management of chronic respiratory conditions. In emergencies like acute bronchospasm, nebulized salbutamol or other rescue therapies are preferred.
Dosage Adjustments
Dosage adjustments should be considered in cases of renal/hepatic dysfunction, metabolic disorders, or any other condition that could affect drug metabolism or clearance.
Side Effects
Common Side Effects:
- Nausea, vomiting
- Headache, dizziness
- Tremors, palpitations
- Restlessness, insomnia
- Skin rash, flushing
- Stomach upset, diarrhea
- Dry mouth, throat irritation
Rare but Serious Side Effects:
- Seizures, arrhythmias
- Severe allergic reactions (anaphylaxis)
- Worsening bronchospasm (paradoxical bronchospasm)
- Hypokalemia (low potassium)
- Hyperglycemia (high blood sugar)
Long-Term Effects:
- Tolerance to bronchodilator effects (with chronic use of salbutamol and theophylline).
- Potassium depletion with long-term theophylline use.
- Cardiovascular effects with long-term use of theophylline.
Contraindications
- Hypersensitivity to any component of the medication
- Severe heart disease, certain arrhythmias
- Severe hypertension
- Peptic ulcers
- Hyperthyroidism
- Pregnancy and breastfeeding (generally avoided)
Drug Interactions
- Beta-blockers: Reduce the bronchodilating effects of salbutamol.
- Certain antidepressants (MAOIs, tricyclics): May interact with salbutamol, increasing the risk of cardiovascular side effects.
- Xanthines (e.g., caffeine, theophylline): Additive effects with choline theophyllinate, increasing the risk of side effects.
- Cimetidine: May inhibit the metabolism of theophylline.
- Some antibiotics (macrolides, quinolones): May increase theophylline levels.
Pregnancy and Breastfeeding
This combination should generally be avoided during pregnancy and breastfeeding due to potential risks to the fetus/infant. The physician must carefully assess the risk-benefit ratio in cases where it is considered essential.
