Purisal syrup is a fast-acting bronchodilator containing Levosalbutamol (1 mg per 5 ml). It is a selective beta-2 adrenergic receptor agonist used to treat and prevent breathing difficulties. Unlike racemic salbutamol, levosalbutamol is a single isomer, which often provides effective relief with fewer cardiovascular side effects like racing heart or tremors. Manufactured by Incepta Pharmaceuticals Ltd., it is a widely prescribed “reliever” for obstructive airway diseases in Bangladesh.
What is Purisal Syrup Used For?
Purisal 1 mg/5 ml syrup is primarily prescribed for:
-
Asthma Management: Treatment and prevention of bronchospasm in adults and children.
-
COPD Relief: Management of reversible obstructive airway diseases like chronic bronchitis and emphysema.
-
Acute Bronchospasm: Relief of wheezing, shortness of breath, and chest tightness.
Clinical Note: While Levosalbutamol is a fast-acting bronchodilator, the syrup form is typically used for maintenance or scheduled relief. In emergency “rescue” situations, a Metered-Dose Inhaler (MDI) or nebulizer solution is usually preferred for faster delivery to the lungs.

Dosage
Dosage should be strictly followed as per a physician’s advice. The standard guidelines for Purisal syrup (1 mg/5 ml) are:
-
Adults & Adolescents (12+ years): 5 ml to 10 ml (1–2 mg) three times daily.

-
Children (2–5 years): 0.1 mg/kg of body weight, three times daily (Maximum 1 mg per dose).
Common Side Effects

-
Fine tremors (especially in the hands)
-
Palpitations or increased heart rate
-
Headache or dizziness

Muscle cramps

Nervousness or restlessness
Important Warnings & Precautions
-
Cardiovascular Disease: Use with caution if you have a history of high blood pressure, heart rhythm disorders, or coronary insufficiency.
-
Diabetes: Levosalbutamol may increase blood glucose levels; diabetic patients should monitor their sugar closely.
-
Hyperthyroidism: Patients with an overactive thyroid may be more sensitive to the stimulant effects of this medication.
-
Pregnancy/Lactation: Use only if the potential benefit justifies the risk to the fetus. It is unknown if it passes into breast milk.

Q: Is Purisal good for a cough?
Purisal is effective if the cough is caused by bronchospasm or asthma. It is not a generic cough suppressant for viral infections or the common cold.
Q: What does Purisal do?
It stimulates beta-2 receptors in the lungs, causing the smooth muscles of the airways to relax. This opens up the bronchial tubes, making it much easier to breathe.
Q: Does Purisal make you sleepy?
No, Purisal is a stimulant. It is more likely to cause restlessness or a “jittery” feeling rather than drowsiness.
Q: Is Levosalbutamol (Purisal) high risk?
It is generally safe but carries risks for patients with pre-existing heart conditions or low potassium. It must be used carefully to avoid cardiovascular stress.
Q: Is Purisal safe during pregnancy?
