Beclomethasone (Inhaled): Uses, Dosing, Side Effects and Indian Brand Names
Inhaled beclomethasone is the prototype ICS and a cornerstone controller medication for asthma. It suppresses chronic airway inflammation without providing immediate bronchodilation, requires regular daily use, and has minimal systemic effects at standard doses.
NEET PG High-Yield: ICS (beclomethasone) is the CONTROLLER drug for asthma -- NOT for acute relief (salbutamol is the reliever). Oral candidiasis is the most common local side effect (prevented by mouth rinsing and spacer). At standard doses, systemic side effects are minimal. Growth retardation in children is small (~1 cm in first year) and does not affect final adult height significantly. The equivalence ratio: beclomethasone HFA dose = roughly half of CFC formulation dose.
Clinical overview
Inhaled beclomethasone is one of the earliest and most widely used inhaled corticosteroids (ICS) and remains a cornerstone controller medication for asthma management worldwide. It is the prototype ICS and the reference drug against which other ICS preparations (budesonide, fluticasone, ciclesonide) are compared for potency. Per GINA guidelines, ICS is the foundation of asthma controller therapy from step 2 onwards and is the single most effective drug class for reducing asthma exacerbations, preventing asthma deaths, and maintaining long-term symptom control. Beclomethasone works by reducing the chronic airway inflammation that underlies asthma pathophysiology -- it is NOT a bronchodilator and provides no immediate symptom relief. The onset of clinical improvement takes 1-2 weeks, and maximum benefit requires 4-8 weeks of regular use. The key clinical message for patients is that ICS must be taken regularly (even when asymptomatic) and is not a rescue medication. In India, beclomethasone is widely available in MDI and DPI formulations and is affordable. Oral candidiasis (thrush) and dysphonia (hoarseness) are the most common local side effects, prevented by rinsing the mouth with water after each use and using a spacer with MDIs. At recommended doses (up to 800 mcg/day in adults), systemic side effects are minimal because the drug is deposited locally with low systemic bioavailability, and the absorbed fraction undergoes first-pass hepatic metabolism. The HFA-formulated beclomethasone (extra-fine particle) achieves better small airway deposition.
Pharmacological class
Beclomethasone (Inhaled) belongs to the Inhaled corticosteroid (ICS; glucocorticoid) class. Inhaled beclomethasone dipropionate is a prodrug that is converted to the active metabolite beclomethasone-17-monopropionate (17-BMP) by esterases in the lungs. 17-BMP binds to intracellular glucocorticoid receptors in airway epithelial cells, inflammatory cells, and smooth muscle cells. The activated receptor translocates to the nucleus and modulates gene transcription: suppressing pro-inflammatory mediators (cytokines IL-4, IL-5, IL-13; chemokines; adhesion molecules; COX-2; iNOS) and inducing anti-inflammatory proteins (lipocortin-1, beta-2 receptors, IkB-alpha). This reduces airway inflammation, oedema, mucus hypersecretion, and bronchial hyperresponsiveness.
Indian brand names and formulations
Available as: Beclate (Cipla), Beconase (GlaxoSmithKline) [nasal], Aerocort (Cipla) [beclomethasone + salbutamol], Beclomethasone MDI (Various manufacturers).
Metered-dose inhaler (MDI): 50 mcg, 100 mcg, 200 mcg, 250 mcg per puff (200 doses). Dry powder inhaler (DPI/Rotacaps): 100 mcg, 200 mcg. Nasal spray: 50 mcg/spray. Combination MDI with salbutamol (Aerocort): beclomethasone 50 mcg + salbutamol 100 mcg per puff.
Regulatory status
Beclomethasone (Inhaled) is classified under Schedule H in India under the Drugs and Cosmetics Act, 1940. Schedule H prescription drug. Inhalers require patient education on correct technique. NLEM 2022 listed. Available in CFC-free HFA formulations.
Indications
- Bronchial asthma (controller therapy -- step 2 onwards per GINA)
- Chronic asthma maintenance (prevention of exacerbations)
- Allergic rhinitis (nasal formulation)
- Nasal polyposis (nasal spray)
Dosing
Asthma (adults): Low dose: 100-200 mcg/day (HFA), Medium dose: 200-400 mcg/day, High dose: >400 mcg/day. Conventional CFC formulation: double these doses. Take BD (twice daily). Children: Low dose: 50-100 mcg/day, Medium: 100-200 mcg/day. Nasal spray (allergic rhinitis): 100 mcg (2 sprays) per nostril BD. Rinse mouth with water after each inhalation use to prevent oral candidiasis. Use a spacer device with MDI for optimal lung deposition and reduced oropharyngeal deposition.
Contraindications
- Primary treatment of acute bronchospasm or status asthmaticus (not a rescue drug)
- Active or quiescent pulmonary tuberculosis (relative -- can be used with concurrent anti-TB therapy)
- Untreated fungal, bacterial, or viral respiratory infections
Adverse effects
- Oral candidiasis/thrush (most common local side effect -- prevented by mouth rinsing and spacer use)
- Dysphonia/hoarseness (steroid myopathy of laryngeal muscles)
- Pharyngitis and cough (local irritation)
- Adrenal suppression (only at high doses >800 mcg/day for prolonged periods)
- Growth retardation in children (small, approximately 1 cm in first year; final adult height generally not affected)
- Osteoporosis (minimal risk at standard doses; relevant at high doses for years)
- Skin thinning and easy bruising (high doses, chronic use)
- Posterior subcapsular cataract and glaucoma (high doses, long-term)
Drug interactions
- CYP3A4 inhibitors (ritonavir, ketoconazole, itraconazole) -- increase systemic absorption of inhaled corticosteroids, risk of Cushing syndrome and adrenal suppression (more relevant for fluticasone than beclomethasone, but caution applies)
- No significant interaction with SABAs, LABAs, montelukast, or antihistamines (safely co-prescribed)
- Rifampicin -- may increase corticosteroid metabolism (clinical relevance for inhaled route is limited)
Pregnancy and lactation
Category C. Inhaled corticosteroids are considered safe and essential in pregnancy for asthma control. Uncontrolled asthma carries far greater risk (hypoxia, preterm delivery, pre-eclampsia) than ICS. Budesonide has the most pregnancy safety data among ICS (Category B), but beclomethasone is also widely used. GINA recommends that pregnant women should continue their asthma controller medications, including ICS.
Exam-style clinical scenario
A 10-year-old girl has asthma symptoms (cough, wheeze) more than twice per week and uses her salbutamol inhaler 3-4 times weekly. She has had one emergency visit in the past 3 months. Her mother is reluctant to start 'steroids.' What should you prescribe and how do you counsel the mother? Answer: This child has uncontrolled persistent asthma requiring step 2 therapy -- a low-dose inhaled corticosteroid (beclomethasone 50-100 mcg/day). Counsel the mother that: (1) Inhaled steroids are NOT the same as oral/body-building steroids; (2) the dose reaching the blood is negligible; (3) ICS prevents airway inflammation, reduces exacerbations, and prevents emergency visits; (4) mouth rinsing after use prevents oral thrush; (5) uncontrolled asthma is far more dangerous than ICS. Demonstrate correct MDI + spacer technique.
Cost in India
INR 120-250 per MDI (200 doses of 100 mcg/puff); Rotacaps: INR 80-150

Frequently Asked Questions
Why is a spacer recommended with beclomethasone MDIs?
A spacer (volumatic chamber) serves three purposes: (1) it slows the aerosol velocity, reducing impaction on the oropharynx and decreasing local side effects (oral candidiasis, dysphonia); (2) it allows more time for propellant evaporation, producing smaller particles that penetrate deeper into the lower airways (increasing lung deposition from ~10-15% to ~20-25%); (3) it eliminates the need for precise coordination between actuation and inhalation, improving drug delivery especially in children and elderly patients.
How do inhaled corticosteroids differ from oral corticosteroids?
Inhaled corticosteroids deliver drug directly to the airway mucosa at the site of inflammation, with minimal systemic absorption. At standard doses, ICS causes negligible systemic effects (no Cushing syndrome, no adrenal suppression, no osteoporosis). Oral corticosteroids (prednisolone) are absorbed systemically and cause widespread effects including all the classic steroid side effects. ICS are for long-term controller therapy; oral steroids are reserved for acute exacerbations (short courses) or severe refractory asthma.
Can inhaled corticosteroids be stopped once asthma is controlled?
No, asthma is a chronic inflammatory disease and ICS controls the underlying inflammation without curing it. Stopping ICS typically leads to recurrence of airway inflammation and symptoms within days to weeks. After sustained good control (3 months), the ICS dose can be STEPPED DOWN to the lowest effective dose but should not be completely stopped in persistent asthma. Complete cessation is only considered in patients who have been completely asymptomatic on the lowest ICS dose for 6-12 months.
