Asthalin Respules (Salbutamol)

Asthalin Respules — Complete Product Description

Overview:-

Asthalin Respules is a fast-acting, prescription-based bronchodilator solution formulated specifically for nebulization — a method of delivering medicine directly into the lungs as a fine, easily breathable mist. Manufactured by Cipla Ltd. — one of India’s most respected and globally recognized pharmaceutical companies — Asthalin Respules is a trusted and clinically well-established rescue medication for the relief of acute and chronic respiratory symptoms associated with asthma, chronic obstructive pulmonary disease (COPD), and other reversible obstructive airway conditions.

Each Asthalin Respule is a single-dose, ready-to-use plastic ampoule containing 2.5 ml of Salbutamol Sulphate solution at a concentration of 2.5 mg per 2.5 ml. The respules are typically supplied in strips of five, making them convenient to store, carry, and use as part of a daily or on-demand respiratory treatment regimen. The solution is administered through a jet nebulizer connected to an air compressor, which converts the liquid into a gentle aerosol mist inhaled steadily through a face mask or mouthpiece — delivering the medication deep into the airways where it is needed most.

Asthalin Respules is classified as a fast-acting bronchodilator — also known as a “reliever” medication — and is used when breathing difficulties arise, rather than as a fixed-schedule daily preventer. Its nebulized delivery makes it particularly valuable for very young children, elderly patients, and those who are too breathless, distressed, or physically limited to coordinate the use of a conventional metered-dose inhaler. In most comprehensive respiratory treatment plans, Asthalin Respules serves as the rescue component and is used alongside a separate daily preventer therapy — typically an inhaled corticosteroid — to address the underlying airway inflammation that drives recurring symptoms.

Active Ingredient

Asthalin Respules contains Salbutamol Sulphate — 2.5 mg per 2.5 ml ampoule — as its sole active pharmaceutical ingredient. Salbutamol, also widely known as Albuterol, is one of the most extensively studied, globally trusted, and clinically proven bronchodilators in the history of respiratory medicine. It is classified as a short-acting beta-2 adrenergic receptor agonist (SABA) — a molecule that acts selectively on the beta-2 receptors located in the smooth muscle of the bronchial airways, triggering rapid and potent relaxation of the breathing passages.

Salbutamol’s decades-long safety record, well-understood mechanism of action, rapid onset of bronchodilation, broad clinical applicability across all age groups, and consistently proven efficacy across the full spectrum of obstructive airway disease make it the active ingredient of choice in short-acting bronchodilator therapy across the world. Asthalin Respules delivers this gold-standard molecule in a liquid nebulizer-ready format — gentle, accessible, and effective.

How It Works — Mechanism of Action?

Salbutamol works by selectively binding to the beta-2 adrenergic receptors present on the smooth muscle cells that surround the bronchial airways — from the trachea all the way down to the terminal bronchioles. Upon binding to these receptors, it activates the enzyme adenylate cyclase, which catalyzes the conversion of adenosine triphosphate (ATP) into cyclic adenosine monophosphate (cAMP). The resulting surge in intracellular cAMP levels activates protein kinase A — an enzyme that prevents the phosphorylation of myosin and reduces intracellular calcium concentration, both of which are the molecular triggers for smooth muscle contraction.

The net result of this cascade is rapid, substantial relaxation of the bronchial smooth muscle along the entire length of the airway tree. Constricted, narrowed airways begin to widen within minutes of the start of nebulization, airflow resistance drops significantly, and the distressing sensations of chest tightness, wheeze, breathlessness, and cough ease quickly and meaningfully. In addition, Salbutamol inhibits the release of bronchoconstricting mediators — including histamine and leukotrienes — from mast cells in the sensitized airway lining, providing an additional protective layer against the acute narrowing.

Bronchodilation begins within 5 to 10 minutes of starting the nebulization session, reaches its peak therapeutic effect within 30 to 60 minutes, and the clinical benefit lasts for 4 to 6 hours — providing a reliable and significant window of respiratory relief.

Therapeutic Uses

Asthalin Respules is indicated for the treatment and prevention of a range of obstructive and reversible airway conditions.

1. Acute Asthma Relief Asthma causes recurrent episodes of airway narrowing, inflammation, and hypersensitivity triggered by allergens, tobacco smoke, cold air, exercise, dust, mould, pet dander, and respiratory infections — producing wheezing, coughing, chest tightness, and acute shortness of breath. Asthalin Respules provides fast, powerful bronchodilation during these acute episodes, rapidly reversing the airway constriction, easing breathing, and helping the patient regain respiratory control within minutes of beginning the nebulization session.

2. Chronic Obstructive Pulmonary Disease (COPD) COPD — encompassing chronic bronchitis and emphysema — is a progressive, long-term lung condition characterized by persistent airway inflammation, obstruction, excess mucus production, and difficulty moving air in and out of the lungs. Asthalin Respules provides fast, meaningful relief from acute COPD exacerbations and day-to-day breathlessness, wheezing, and chronic cough, improving the patient’s ability to carry out routine daily activities and significantly enhancing quality of life.

3. Bronchospasm — Treatment and Prevention Bronchospasm is a sudden tightening of the muscles in the walls of the bronchi, causing acute and often frightening difficulty in breathing. Asthalin Respules is highly effective in treating active bronchospasm and can also be used prophylactically before exercise or anticipated exposure to known triggers to prevent its occurrence.

4. Prevention of Exercise-Induced Bronchospasm For patients whose airways constrict during or after physical activity, Asthalin Respules can be administered via nebulizer before exercise to keep the airways open, enabling patients to remain physically active without fear of breathlessness or respiratory distress.

5. Emergency Asthma Management During severe asthma attacks — particularly in a hospital or home setting where a nebulizer is available — Asthalin Respules functions as a critical rescue therapy. Its nebulized delivery ensures that even severely breathless patients who cannot coordinate an inhaler can still receive therapeutic benefit effectively through a face mask.

6. Airway Clearance Support By relaxing and widening the airways, Asthalin Respules facilitates the natural clearance of mucus and secretions from the respiratory tract, reducing congestion, improving airflow, and further enhancing breathing comfort.

Who Can Use Asthalin Respules?

Asthalin Respules is suitable for use in adults, adolescents, and children under the supervision of a qualified medical professional. It is not recommended for use in children below two years of age, as clinical safety data have not been adequately established for this age group. In children aged two to four years, use should be approached with particular caution and only under direct medical guidance. Patients with known hypersensitivity or allergic reactions to Salbutamol, lactose — a milk protein found in some formulations — or any other ingredient in Asthalin Respules should not use this product. Patients who are at risk of preterm labor or miscarriage should also avoid using Asthalin Respules unless specifically directed by their doctor, as Salbutamol can relax uterine smooth muscle.

Dosage & Administration:-

Asthalin Respules must be used exactly as prescribed by a qualified doctor. The dose and frequency will depend on the patient’s age, clinical condition, severity of symptoms, and overall treatment plan. It must only be used with a jet nebulizer connected to an air compressor — it is not suitable for use with ultrasonic nebulizers, which may affect drug delivery. The solution should be used immediately after opening. Do not store an opened respule for later use — any unused portion must be discarded.

Standard Dosage Guidelines:

For adults and adolescents, the standard dose is 2.5 mg (one full 2.5 ml respule) administered by nebulization, up to three to four times daily as directed by the doctor. In cases of acute severe asthma requiring hospital-level management, higher or more frequent doses may be administered under close medical supervision. For children, the dose is typically lower and will be specifically determined by the treating physician based on body weight and severity of the condition.

How to Use the Nebulizer:

1. Wash your hands thoroughly before handling the respule and nebulizer equipment.
2. Inspect the respule to ensure it is undamaged, clear, and has not exceeded its expiry date.
3. Twist off the top of the respule ampoule and squeeze all of the liquid contents into the nebulizer chamber or medicine cup — do not dilute unless specifically instructed by the doctor.
4. Use the respule immediately after opening — do not store or reuse an opened ampoule.
5. Connect the nebulizer cup to the face mask or mouthpiece and attach it securely to the air compressor tubing.
6. Place the face mask securely and comfortably over the nose and mouth — or place the mouthpiece between the lips, forming a firm seal — ensuring no medicine escapes around the edges.
7. Switch on the air compressor and breathe in the resulting mist slowly and steadily through the mouth, as deeply as possible, throughout the nebulization session.
8. Continue inhaling until the nebulizer chamber is empty, which typically takes 5 to 15 minutes depending on the nebulizer flow rate.
9. After completing the session, rinse the mouth thoroughly with water and spit it out — do not swallow. If a face mask was used, wash the face around the mask area to prevent skin irritation from residual droplets.
10. Clean all parts of the nebulizer thoroughly after each session, following the manufacturer’s instructions, to prevent contamination and ensure consistent drug delivery in subsequent uses.

Do not mix Asthalin Respules with any other inhalation medicine in the nebulizer chamber unless specifically directed by a doctor, as compatibility with other nebulized solutions has not been universally established. Do not exceed the prescribed dose.

Side Effects:-

Asthalin Respules is generally safe and well-tolerated when used as directed. Common side effects include fine tremors — particularly of the hands — headache, palpitations, increased heart rate, muscle cramps, nervousness, restlessness, nausea, vomiting, dizziness, sleepiness, dryness or soreness of the throat, nasal congestion, cough, and upper respiratory tract infections. These side effects are typically mild in nature and tend to resolve on their own as the body adjusts to the medication.

Practical tips for managing specific side effects include relaxing and avoiding caffeine to ease tremors, resting and limiting stimulants to manage palpitations, sipping warm liquids or using throat lozenges to soothe throat irritation, and staying well hydrated while stretching regularly to alleviate muscle cramps.

More serious side effects that require prompt medical attention include severe chest pain, very rapid or noticeably irregular heartbeat, extreme dizziness or fainting, swelling of the face, lips, tongue, or throat, skin rashes, difficulty breathing that worsens after using the medication, and signs of a severe systemic allergic reaction.

Paradoxical bronchospasm — a rare but important adverse event where the airways constrict rather than open after nebulization — can occasionally occur. If breathing becomes harder rather than easier during or immediately after a session, the treatment must be stopped at once and urgent medical attention sought.

Taking a higher than recommended dose significantly increases the risk of serious side effects, including seizures, severe chest pain, extreme nervousness, dry mouth, intense dizziness, and irregular heartbeat. Seek emergency medical care immediately if an overdose is suspected.

Precautions & Warnings:-

Before using Asthalin Respules, patients must inform their doctor about all existing health conditions — particularly heart disease or cardiac arrhythmias, high blood pressure, overactive thyroid gland (hyperthyroidism), diabetes, low blood potassium levels (hypokalemia), liver or kidney problems, stomach ulcers, seizure disorders, or any history of severe allergic reactions to medications.

Asthalin Respules may cause a drop in blood potassium levels (hypokalemia), which can increase the risk of cardiac arrhythmias — an effect that may be compounded by concurrent use of xanthine derivatives, corticosteroids, diuretics, or long-term laxatives. Patients with pre-existing low potassium levels should use this medication with heightened caution and under close medical monitoring.

Blood glucose levels may rise with use, requiring diabetic patients to monitor their levels closely and report any significant fluctuations to their doctor for appropriate management.

Alcohol consumption should be avoided or kept to a minimum during treatment, as it may intensify drowsiness and dizziness. Patients who feel dizzy or shaky after a nebulization session should not drive, operate heavy machinery, use tools, or cycle until they feel fully recovered. Smoking must be strictly avoided throughout the course of treatment, as it causes progressive and irreversible lung damage and directly undermines the effectiveness of bronchodilator therapy.

Do not discontinue Asthalin Respules without consulting a doctor, even if symptoms appear to have improved — stopping treatment suddenly can cause breathing problems to return or worsen. Patients with a history of heart problems such as angina, previous heart attacks, or irregular heartbeats should use Asthalin Respules under particularly close medical supervision.

During pregnancy, Asthalin Respules should only be used when clearly necessary and when the clinical benefits outweigh any potential risks to the developing baby — particularly during the first trimester and near the time of delivery, given Salbutamol’s ability to relax uterine smooth muscle. During breastfeeding, a doctor should be consulted, as it is not fully established whether Salbutamol passes into breast milk in clinically significant quantities.

Drug Interactions:-

Patients must provide their doctor with a complete list of all medications, supplements, vitamins, and herbal products they are currently taking before beginning treatment. Beta-blockers — including Propranolol, Atenolol, Metoprolol Succinate, and Labetalol — may reduce or completely block the bronchodilatory effect of Salbutamol and should generally be avoided in patients with asthma and COPD. Diuretics such as Furosemide and Hydrochlorothiazide can compound the potassium-lowering effect of Salbutamol, increasing the risk of hypokalemia and cardiac arrhythmias, and require careful monitoring. Xanthine derivatives such as Theophylline and Aminophylline used concurrently may also worsen hypokalemia and exacerbate cardiovascular side effects. Monoamine oxidase inhibitors (MAOIs) and tricyclic antidepressants may amplify the cardiovascular effects of Salbutamol. Corticosteroids — whether oral, injected, or inhaled — can further reduce potassium levels when combined with Salbutamol. Medicines for heart conditions, including Digoxin, may have their effects altered when used alongside Salbutamol and require monitoring. Other bronchodilators and sympathomimetic medicines used concurrently may increase the overall side effect burden.

Storage Instructions

Store Asthalin Respules in a cool, dry place below 30°C, away from direct sunlight, heat sources, and moisture. Do not refrigerate or freeze. Keep the respules in their original strip packaging until immediately before use, as exposure to light may degrade the solution. Always inspect the ampoule for any signs of leakage, cloudiness, discolouration, or visible particles before use — do not use if the solution does not appear clear and colourless. Always check the expiry date printed on the packaging before each use. Once opened, the respule must be used immediately and any unused portion must be discarded — opened ampoules must never be stored for later use. Keep out of the reach and sight of children and pets at all times.

Asthalin Respules vs. Asthalin Inhaler — Understanding the Difference

Both Asthalin Respules and Asthalin Inhaler contain the same active ingredient — Salbutamol — and serve the same fundamental purpose of providing fast-acting bronchodilatory relief. The key difference lies in the mode of delivery. The Asthalin Inhaler is a compact pressurized MDI requiring coordinated hand-breath actuation, making it ideal for adults and older children who can master the inhalation technique. Asthalin Respules, by contrast, require no coordination whatsoever — the patient simply breathes normally through a face mask or mouthpiece connected to a nebulizer — making them the preferred choice for infants, young children, elderly patients, those in severe respiratory distress, and anyone unable to use a conventional inhaler effectively. Your doctor will recommend the most appropriate delivery format based on your age, clinical condition, and ability to use respiratory devices correctly.

Why Choose Asthalin Respules?

Asthalin Respules brings together the proven therapeutic power of Salbutamol with the unmatched accessibility and inclusivity of nebulization therapy. It removes the physical and cognitive barriers associated with conventional inhalers, ensuring that fast-acting bronchodilator relief reaches the patients who need it most — regardless of age, coordination ability, or severity of respiratory distress. Its ready-to-use single-dose ampoule format eliminates preparation errors, guarantees dose accuracy, and minimizes the risk of contamination.

Backed by Cipla’s decades of pharmaceutical innovation and an extensive global body of clinical evidence, Asthalin Respules continues to be one of the most trusted and widely recommended bronchodilator nebulizer solutions prescribed by respiratory specialists, paediatricians, and general practitioners across India and internationally — for patients who need reliable, rapid, and deeply effective airway relief delivered in the most accessible way possible.

Always use Asthalin Respules under the guidance of a qualified medical professional. This product is available on prescription only.
