Combimist L Inhaler

Combimist L Inhaler is a pressurized metered-dose inhaler (pMDI) containing a fixed-dose combination of Levosalbutamol and Ipratropium Bromide. It is indicated for the treatment and management of reversible airways obstruction, such as in asthma and chronic obstructive pulmonary disease (COPD). This combination therapy offers both rapid bronchodilation and sustained control, making it a cornerstone in respiratory management for patients requiring dual bronchodilator therapy. Its optimized formulation ensures efficient drug delivery to the lower airways, providing comprehensive symptom relief and improved lung function.

Features

• Contains Levosalbutamol (levo-isomer of Salbutamol) 50 mcg and Ipratropium Bromide 20 mcg per puff
• Delivered via a pressurized metered-dose inhaler with a dose counter
• Rapid onset of action, typically within 5–15 minutes
• Long duration of effect, lasting up to 6 hours
• Portable, pocket-sized device for on-the-go use
• Compatible with spacer devices for improved lung deposition in certain patient populations
• Each canister contains 200 metered doses

Benefits

• Provides rapid relief from acute bronchospasm and shortness of breath
• Offers dual-mechanism bronchodilation targeting both beta-2 adrenergic and muscarinic receptors
• Reduces the frequency and severity of asthma and COPD exacerbations
• Improves exercise tolerance and overall quality of life
• Minimizes the need for rescue medication with regular use as prescribed
• Enhances lung function parameters such as FEV1 and peak expiratory flow

Common use

Combimist L Inhaler is commonly prescribed for the management of reversible obstructive airways diseases. It is widely used in patients with asthma who exhibit an inadequate response to short-acting beta-2 agonists alone, as well as in COPD patients—particularly those with chronic bronchitis—who require combined bronchodilator therapy. It is suitable for both scheduled maintenance therapy and as-needed relief for breakthrough symptoms, depending on the treatment plan devised by the healthcare provider.

Dosage and direction

The typical dosage for adults and adolescents over 12 years is two puffs, up to four times daily, or as directed by a physician. Do not exceed 12 puffs in 24 hours. Shake the inhaler well before each use. Exhale fully, place the mouthpiece between the lips, and inhale deeply and slowly while pressing the canister. Hold breath for 10 seconds, then exhale slowly. Wait at least one minute before administering a second puff if required. Rinse the mouth with water after each use to reduce the risk of oropharyngeal side effects.

Precautions

• Not recommended for initial treatment of acute asthma attacks; a short-acting beta-2 agonist monotherapy may be preferred
• Use with caution in patients with cardiovascular disorders, including hypertension, arrhythmias, or ischemic heart disease
• May cause paradoxical bronchospasm; discontinue immediately if it occurs
• Avoid contact with eyes; may cause pupillary dilation and blurred vision if sprayed directly
• Not a substitute for corticosteroids; anti-inflammatory treatment should be maintained as prescribed
• Monitor for signs of hypokalemia, especially in patients taking xanthine derivatives or diuretics

Contraindications

• Hypersensitivity to Levosalbutamol, Ipratropium Bromide, or any component of the formulation
• History of hypersensitivity to atropine or its derivatives
• Patients with narrow-angle glaucoma
• Severe cardiac arrhythmias
• Hypertrophic obstructive cardiomyopathy
• Not intended for children under 12 years of age

Possible side effects

Common side effects may include:

• Dry mouth
• Headache
• Tremor
• Throat irritation
• Cough
• Palpitations
• Nausea

Less common but serious side effects:

• Tachycardia
• Paradoxical bronchospasm
• Urinary retention
• Increased intraocular pressure
• Hypokalemia
• Allergic reactions such as rash, angioedema, or anaphylaxis (rare)

Drug interaction

• Beta-blockers (e.g., propranolol) may antagonize bronchodilator effects
• Concomitant use with other anticholinergic drugs may increase side effects
• Xanthine derivatives (e.g., theophylline) and diuretics may enhance the risk of hypokalemia
• Monoamine oxidase inhibitors (MAOIs) and tricyclic antidepressants may potentiate cardiovascular effects
• Use caution with other sympathomimetic agents due to additive effects

Missed dose

If a dose is missed, take it as soon as remembered. If it is nearly time for the next dose, skip the missed dose and resume the regular schedule. Do not double the dose to make up for a missed one.

Overdose

Overdose may manifest as exaggerated pharmacologic effects such as tachycardia, tremor, nausea, dizziness, hypokalemia, and arrhythmias. Anticholinergic symptoms like dry mouth, blurred vision, and urinary retention may also occur. Treatment is supportive and symptomatic. Cardiac monitoring is advised. Consider the use of a cardioselective beta-blocker in cases of severe beta-2 agonist overdose, bearing in mind the risk of bronchospasm.

Storage

Store at room temperature (15–30°C). Do not expose to direct sunlight or excessive heat. Keep the canister away from open flame or incineration. Do not puncture or break even after use. Keep out of reach of children.

Reviews

“After switching to Combimist L, my COPD symptoms are much better controlled. I use it twice daily and can now take walks without getting breathless.” – Margaret T., 68

“As an asthma specialist, I find Combimist L offers a good balance of rapid relief and duration of action. The dose counter is a practical feature for adherence.” – Dr. A. Sharma, Pulmonologist

“Effective, but I did experience some dry mouth initially. It improved with regular use and rinsing my mouth after each dose.” – James L., 54
