Usage
This combination medication is used to relieve coughs associated with various respiratory conditions, including:
- Chronic bronchitis
- Bronchial asthma
- Emphysema
- Other bronchopulmonary disorders characterized by bronchospasm, mucus plugging, and difficulty expectorating.
Pharmacological Classification: This combination product includes drugs from several classifications:
- Expectorant (Ammonium Chloride)
- Mucolytic (Bromhexine)
- Bronchodilator (Salbutamol)
- Decongestant/Anesthetic (Menthol)
Mechanism of Action: Each component contributes to the overall effect:
- Ammonium chloride irritates the bronchial mucosa, increasing fluid production and thinning mucus.
- Bromhexine breaks down mucopolysaccharides, decreasing mucus viscosity.
- Salbutamol stimulates beta-2 adrenergic receptors, relaxing bronchial smooth muscle and causing bronchodilation.
- Menthol acts as a local anesthetic and decongestant, providing a cooling sensation and relieving throat irritation.
Alternate Names
This combination may be marketed under various brand names, including Eascof Expectorant, Caryl Cough Syrup, SB Forte syrup, and C S Plus Syrup. Some formulations may substitute Terbutaline for Salbutamol or Guaifenesin for Ammonium Chloride. Always check the product composition to confirm the ingredients.
How It Works
Pharmacodynamics: The combination exerts its therapeutic effect through the combined actions of its constituents, resulting in expectorant, mucolytic, bronchodilator, and decongestant effects.
Pharmacokinetics:
- Absorption: All components are absorbed orally, with varying extent and rate.
- Metabolism: Each component has a different metabolic pathway. Salbutamol and Bromhexine are primarily metabolized by the liver.
- Elimination: Salbutamol is excreted mainly in the urine, while Bromhexine is eliminated in both urine and feces. Ammonium chloride is primarily excreted by the kidneys. Menthol is extensively metabolized in the liver and excreted in urine and feces.
Mode of Action:
- Ammonium Chloride: Increases respiratory secretions by irritating the respiratory tract.
- Bromhexine: Depolymerizes mucopolysaccharides, thereby reducing mucus viscosity.
- Salbutamol: Stimulates beta-2 adrenergic receptors leading to bronchodilation.
- Menthol: Acts on cold receptors causing a cooling sensation and mild local anesthetic effect.
Dosage
Dosage varies based on age, medical condition, and individual response. Always adhere to the prescribed dosage and consult with a physician for appropriate recommendations.
Standard Dosage
Adults: Typically, 10-20ml three times daily, adjusted as needed based on clinical response.
Children: Dosage should be determined by a physician based on weight or age. This combination is generally not recommended for children under 6 years of age.
Special Cases:
- Elderly Patients: Dosage adjustment may be needed based on organ function.
- Patients with Renal Impairment: Dose modification based on creatinine clearance is often necessary.
- Patients with Hepatic Dysfunction: Adjust dosage according to the degree of impairment.
- Patients with Comorbid Conditions: Close monitoring for patients with conditions such as diabetes, cardiovascular diseases, hypertension, hyperthyroidism, and seizures, with dosage adjustments as necessary.
Clinical Use Cases
Dosage in specific clinical settings should be determined by the attending physician based on individual patient requirements and clinical status.
Dosage Adjustments
Dose modification is essential based on patient-specific factors, including renal/hepatic dysfunction, metabolic disorders, and genetic polymorphisms affecting drug metabolism.
Side Effects
Common Side Effects:
Nausea, vomiting, headache, dizziness, tremors, palpitations, increased heart rate, muscle cramps, sweating, skin rash, sleepiness, diarrhea, bloating, indigestion.
Rare but Serious Side Effects:
Allergic reactions (skin rash, itching, swelling, difficulty breathing), severe hypotension, cardiac arrhythmias, paradoxical bronchospasm, hypokalemia.
Long-Term Effects:
Tolerance to salbutamol, worsening of underlying respiratory conditions if not managed effectively.
Adverse Drug Reactions (ADR):
Any of the rare but serious side effects listed above require immediate medical attention.
Contraindications
Hypersensitivity to any ingredients, severe cardiovascular disorders (e.g., uncontrolled hypertension, coronary insufficiency, arrhythmias), epilepsy or history of seizures.
Drug Interactions
- Beta-blockers: May antagonize salbutamol’s effects.
- Diuretics: May potentiate hypokalemia caused by salbutamol.
- MAO inhibitors and tricyclic antidepressants: May potentiate salbutamol’s cardiovascular effects.
- Theophylline: May increase the risk of adverse effects.
- Other sympathomimetic agents: Concomitant use is not recommended.
Pregnancy and Breastfeeding
Pregnancy: Safety not definitively established. Salbutamol crosses the placenta, posing potential fetal risks. Use with extreme caution only if benefits outweigh risks.
Breastfeeding: Salbutamol is excreted in breast milk. Limited data on other components. Exercise caution and consider potential risks to the infant.
