Question

Salbutamol is used as _______

• A. Antacid
• B. Bronchodilator
• C. Antidiabetic
• D. Antimalarial

Hint:

Salbutamol is a short-acting bronchodilator used for quick relief in asthma.

Answer 1

The Correct Option is B

Concept:
Salbutamol is a short-acting \(\beta_2\)-adrenergic agonist.

Step 1: Bronchospasm occurs due to contraction of bronchial smooth muscle.

Step 2: Salbutamol stimulates \(\beta_2\)-receptors in bronchial smooth muscle.

Step 3: This causes relaxation of bronchial smooth muscle.

Step 4: As a result, airways dilate and breathing improves.

Step 5: Therefore, salbutamol is used as a bronchodilator. \[ \boxed{\text{Bronchodilator}} \]
