Usage
Beclometasone + Salbutamol is prescribed for the maintenance treatment of asthma and chronic obstructive pulmonary disease (COPD) in patients where the use of a combination product is appropriate. It is not intended for relieving acute asthma attacks.
Pharmacological Classification:
- Beclometasone: Corticosteroid, Anti-inflammatory
- Salbutamol: β₂-adrenergic agonist, Bronchodilator
Mechanism of Action: Beclometasone reduces airway inflammation, while Salbutamol relaxes the bronchial smooth muscles, widening the airways.
Alternate Names
While “Beclometasone + Salbutamol” is the generic name, the combination is marketed under various brand names, including Ibicar S. Regional variations in nomenclature might exist.
How It Works
Pharmacodynamics: Beclometasone exerts its anti-inflammatory action by binding to glucocorticoid receptors in the cytoplasm of airway cells. This complex translocates to the cell nucleus, modulating gene transcription and ultimately decreasing the production of inflammatory mediators. Salbutamol, a short-acting β₂-agonist, relaxes bronchial smooth muscles by stimulating β₂-adrenergic receptors, leading to bronchodilation.
Pharmacokinetics: Following inhalation, both drugs are absorbed systemically to varying extents. Beclometasone is metabolized primarily in the liver via CYP3A4 enzymes, whereas Salbutamol is metabolized in the liver and excreted primarily in the urine.
Elimination Pathways:
- Beclometasone: Primarily hepatic metabolism and biliary excretion.
- Salbutamol: Primarily renal excretion.
Dosage
Standard Dosage
Adults:
The standard dose is two inhalations (puffs) two to four times daily. The maximum daily dose should not exceed 12 inhalations. The dose is titrated according to the individual patient’s response and the severity of their condition.
Children (6 years and above):
One to two inhalations twice daily or as directed by the physician. The maximum daily dose generally should not exceed eight inhalations. Adult supervision is recommended.
Special Cases:
- Elderly Patients: Dosage adjustments may be necessary based on individual patient needs and response to therapy.
- Patients with Renal Impairment: Caution should be exercised in patients with renal impairment. Dose adjustments may be required.
- Patients with Hepatic Dysfunction: Caution should be exercised in patients with hepatic impairment.
- Patients with Comorbid Conditions: Pre-existing conditions like diabetes, cardiovascular diseases, hyperthyroidism, and hypokalemia warrant careful consideration.
Clinical Use Cases
Beclometasone + Salbutamol is not indicated for acute management in settings such as intubation, surgical procedures, mechanical ventilation, ICU use, or emergency situations. Its role is in the long-term control of asthma and COPD.
Dosage Adjustments
Dosage adjustments should be individualized based on patient response, disease severity, and the presence of renal or hepatic impairment. Genetic polymorphisms affecting drug metabolism may also necessitate dosage modifications.

Adverse Drug Reactions (ADR)
Severe allergic reactions, paradoxical bronchospasm, and significant hypokalemia require immediate medical attention.
Contraindications
- Hypersensitivity to beclometasone, salbutamol, or any other component of the formulation.
- Untreated respiratory infections.
Drug Interactions
- β-blockers (may antagonize the bronchodilator effects of salbutamol)
- Diuretics (may potentiate hypokalemia)
- Xanthine derivatives (may increase the risk of cardiac arrhythmias)
- Tricyclic antidepressants (may enhance the cardiovascular effects of salbutamol)
- Some general anesthetics
Pregnancy and Breastfeeding
This combination should be used during pregnancy and breastfeeding only if the potential benefits outweigh the risks.

Popular Combinations
Beclometasone + Salbutamol is itself a popular combination for managing asthma and COPD.
Precautions
Assess patients for allergies, comorbidities, and potential drug interactions before initiating therapy. Monitor for side effects and adjust the dosage accordingly. Counsel patients on proper inhaler technique. Advise patients to rinse their mouths after each inhalation to minimize the risk of oral thrush.
FAQs (Frequently Asked Questions)
A: Adults: 2 inhalations 2-4 times daily (max 12/day). Children (6+ years): 1-2 inhalations twice daily (max 8/day).
Q2: Can this combination be used to treat acute asthma attacks?
A: No, this medication is for maintenance therapy and is not suitable for treating acute asthma attacks. A short-acting bronchodilator like Salbutamol alone should be used for acute exacerbations.
Q3: What are the common side effects?
A: Common side effects include oral thrush, hoarseness, throat irritation, headache, tremor, and palpitations.
Q4: What are the important drug interactions?
A: Beta-blockers, diuretics, xanthine derivatives, and some antidepressants can interact with Beclometasone + Salbutamol.
Q5: Is it safe to use during pregnancy and breastfeeding?
A: Use during pregnancy and breastfeeding should be carefully considered and only when the potential benefits outweigh the risks.
Q6: What precautions should be taken in elderly patients?
A: Dosage adjustments may be necessary in the elderly, considering potential comorbidities and age-related physiological changes.
Q7: How should patients be counseled on using the inhaler?
A: Provide clear instructions on proper inhaler technique, including shaking the inhaler, exhaling fully, inhaling slowly and deeply while activating the inhaler, and holding the breath for a few seconds.
Q8: How can the risk of oral candidiasis be reduced?
A: Advise patients to rinse their mouths with water after each inhalation and to use a spacer device if prescribed.
Q9: What should be done if a patient experiences paradoxical bronchospasm?
A: Paradoxical bronchospasm is a serious side effect. Discontinue the medication immediately and seek alternative treatment.
