Which of the following medications is commonly used for asthma treatment?

Ibuprofen
Metformin
Beta agonist inhaler
Aspirin

The correct answer is: Beta agonist inhaler

The choice of a beta agonist inhaler as a common medication for asthma treatment is based on its mechanism of action and clinical effectiveness in managing asthma symptoms. Beta agonists, such as albuterol, work by stimulating beta-2 adrenergic receptors in the lungs, leading to the relaxation of bronchial smooth muscle. This results in bronchodilation, which is crucial for relieving wheezing, shortness of breath, and other obstructive symptoms associated with asthma. These inhalers can be classified as short-acting or long-acting, providing options for both acute relief and ongoing management of asthma. In contrast, the other medications listed serve different medical purposes. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) primarily used for pain relief and inflammation, and is not indicated for asthma treatment. Metformin is an oral medication used to manage type 2 diabetes and has no role in respiratory conditions. Aspirin, another NSAID, may actually exacerbate asthma symptoms in some individuals due to its potential to induce bronchospasm in aspirin-sensitive asthma patients. Therefore, among the options provided, the beta agonist inhaler is the most appropriate and effective choice for asthma management.
