Which of the following is NOT a long-acting beta agonist?

1. Formoterol

2. Pirbuterol

3. Salmeterol

4. Arformoterol

The correct answer is: Pirbuterol

Long-acting beta agonists (LABAs) are a type of medication commonly used to treat asthma and chronic obstructive pulmonary disease (COPD). They work by relaxing the muscles in the airways, making it easier to breathe. Option A Formoterol is a long-acting beta agonist and is commonly used to treat asthma and COPD. It works by stimulating beta-2 receptors in the airway muscles, leading to muscle relaxation. Option B: Pirbuterol is a short-acting beta agonist, which means it has a shorter duration of action compared to long-acting beta agonists. It is used for the short-term relief of symptoms in asthma and COPD. Option C: Salmeterol is a long-acting beta agonist that works similarly to formoterol. It is used for the maintenance treatment of asthma and COPD
