Asthalin Respules (Salbutamol)

What Are Asthalin Respules?

Asthalin Respules are single-use ampoules containing a sterile solution of Salbutamol sulfate. Each 2.5 mL respule delivers 2.5 mg of Salbutamol, intended for inhalation via a nebulizer. This formulation allows for rapid delivery of the medication directly to the lungs, providing quick relief from symptoms associated with asthma and COPD.

How Do Asthalin Respules Work?

Salbutamol, the active ingredient in Asthalin Respules, is a selective β₂-adrenergic agonist. It acts on β₂-receptors in the bronchial smooth muscles, leading to muscle relaxation and subsequent bronchodilation. This process opens up the airways, facilitating easier airflow and alleviating symptoms such as wheezing, coughing, and shortness of breath. The effects typically begin within 5 minutes and can last for 4 to 6 hours.

Indications for Use

Asthalin Respules are indicated for:

• Asthma: For the relief and prevention of bronchospasm associated with asthma.
• Chronic Obstructive Pulmonary Disease (COPD): To manage chronic bronchospasm in conditions like chronic bronchitis and emphysema.
• Acute Severe Asthma: As part of the emergency treatment for status asthmaticus.
• Exercise-Induced Bronchospasm: To prevent bronchospasm triggered by physical activity.

Dosage and Administration

Adults and Children (4 years and above):

The usual dose is 2.5 mg to 5 mg via nebulization, up to four times a day. In cases of acute exacerbation, higher doses may be administered under medical supervision, with a maximum of 40 mg per day.

Infants (under 18 months):

Use is generally not recommended due to limited clinical data. If prescribed, close monitoring is essential, and supplemental oxygen therapy may be considered.

Administration Steps:

• Twist off the top of the respule.
• Squeeze the entire contents into the nebulizer chamber.
• Attach the nebulizer to the air compressor and inhale the mist through a mouthpiece or mask as directed.
• Use immediately after opening; do not store opened respules.
• Rinse the mouth after inhalation to minimize throat irritation.
