PulmoCare Inhaler is used for:
- Bronchospasm: It treats or prevents bronchospasm in bronchial asthma and reversible airway obstruction related to conditions such as bronchitis and emphysema.
- Exercise-Induced Bronchospasm: PulmoCare is effective in relieving acute breathlessness (dyspnoea) and can also be used prophylactically, taken 15 minutes before exercise or exposure to allergens to prevent exercise-induced asthma.
Pharmacology:
The active ingredient in PulmoCare Inhaler is Salbutamol, a selective β2-adrenoceptor agonist.
- It primarily targets the β2-receptors on bronchial smooth muscles, causing bronchodilation and improving airflow in conditions like asthma.
- Salbutamol has a fast onset (within 5 minutes) and provides short-acting relief (lasting 4-6 hours).
- It also helps in reducing inflammation by inhibiting the release of mediators like histamine, neutrophil chemotactic factor, and prostaglandin D2 from mast cells, which are responsible for bronchoconstriction.
Dosage:
For Acute Bronchospasm Relief:
- Adults: 1-2 puffs as needed. The maximum dose is up to 8 puffs per day.
- Children: Half the adult dose.
To Prevent Exercise-Induced Bronchospasm:
- Adults: 2 puffs 15 minutes before exercise or allergen exposure, up to 4 times a day.
- Children: Half the adult dose.
Chronic Therapy:
- Adults: 2 puffs (200 mcg) up to four times daily.
- Children: 2 puffs (200 mcg) up to four times daily.
Always follow the physician's instructions for proper dosage.
Administration:
Correct inhaler technique is essential for proper drug delivery to the lungs. Follow these steps:
- Remove the cap from the inhaler.
- Shake the inhaler vigorously at least 6 times before each use.
- If the inhaler is new or hasn’t been used for over a week, shake it and release one puff into the air to ensure it works.
- Exhale fully, hold the inhaler upright, and place the mouthpiece between your teeth, closing your lips around it.
- Inhale deeply and slowly while pressing the canister firmly to release the medicine.
- Hold your breath for at least 10 seconds, or as long as comfortable.
- If more than one puff is required, wait 1 minute between puffs.
- After use, replace the cap and rinse your mouth with water.
- Cleaning: Clean the inhaler weekly by removing the canister, rinsing the actuator and cap in warm water (not the canister), and letting them dry before reassembling.
Drug Interactions:
- Non-selective Beta-blockers (e.g., Propranolol): Should be avoided with PulmoCare as they may antagonize the effects of Salbutamol.
- Potential for Hypokalemia: β2-agonists may cause low potassium levels, especially when combined with xanthine derivatives, steroids, diuretics, or hypoxia. Monitor serum potassium levels in such cases.
Contraindications:
- Hypersensitivity: Do not use in patients allergic to Salbutamol or other components of the inhaler.
Side Effects:
PulmoCare is generally well tolerated, but some side effects may occur:
- Tremors, anxiety, and muscle cramps.
- Headaches, palpitations, and tachycardia (increased heart rate).
- Cardiac arrhythmias (like atrial fibrillation, supraventricular tachycardia, and extrasystoles).
- Mouth and throat irritation from inhalation.
Pregnancy & Lactation:
- Pregnancy Category C: PulmoCare should be used during pregnancy only if the benefit outweighs the risk to the fetus, as there are no adequate studies in pregnant women.
- Lactation: It is unknown whether Salbutamol passes into breast milk, so it should be used cautiously in nursing mothers.
Precautions & Warnings:
Paradoxical Bronchospasm: Rarely, PulmoCare may cause paradoxical bronchospasm, which can be life-threatening. If this occurs, discontinue the inhaler immediately and seek alternative therapy.
Cardiovascular Effects: Salbutamol may cause changes in heart rate, blood pressure, and ECG changes (like flattened T waves and QT interval prolongation). Use with caution in patients with heart disease, arrhythmias, or hypertension.
Hypersensitivity: Immediate reactions such as urticaria, angioedema, and anaphylaxis may occur. Discontinue if these occur.
Coexisting Conditions: Use cautiously in patients with diabetes, hyperthyroidism, or seizure disorders. High doses may worsen diabetes and ketoacidosis.
Special Populations:
- Children: PulmoCare is effective and safe in children 4 years and older.
Therapeutic Class:
PulmoCare is classified as a short-acting selective β2-adrenoceptor stimulant.
Storage Conditions:
- Store below 30°C, and keep away from heat, sunlight, and moisture.
- Do not puncture, break, or burn the pressurized canister, even when empty.
- Keep out of reach of children and store away from eyes.
- Do not freeze.
