Which medication is most commonly used for immediate relief of bronchospasm in asthmatic patients?

Short-acting beta-agonists are the medications most commonly used for immediate relief of bronchospasm in patients with asthma. These medications work by rapidly relaxing the smooth muscle in the airways, leading to bronchodilation and facilitating easier airflow. Their onset of action is typically within minutes, making them ideal for acute asthma symptoms and exacerbations.

In clinical practice, short-acting beta-agonists are often referred to as "rescue inhalers" because they provide quick relief during asthma attacks or when symptoms suddenly worsen. For example, medications like albuterol are commonly used in emergency situations due to their effectiveness and quick action.

Other options such as corticosteroids are used for long-term control and management of inflammation in asthma but do not provide immediate relief for acute symptoms. Long-acting beta-agonists are intended for maintenance therapy and cannot be relied upon for quick relief. Anticholinergics may play a role in certain situations but are not typically the first-line treatment for acute bronchospasm. Therefore, the short-acting beta-agonists stand out as the most suitable choice for immediate asthma relief.
