Which class of drugs should all asthma patients keep on hand for sudden symptoms?

Short-acting beta-2 agonists are the recommended class of drugs for all asthma patients to keep on hand for sudden symptoms. These medications, such as albuterol, act quickly to relax the muscles of the airways, leading to a rapid improvement in breathing. They are specifically designed for quick relief, making them ideal for use during an asthma attack or when experiencing acute symptoms. These bronchodilators provide prompt relief of wheezing, coughing, chest tightness, and shortness of breath, effectively managing exacerbations and improving overall respiratory function.

In contrast, long-acting beta-adrenergic agonists are intended for maintenance therapy and have a longer duration of action, but they do not provide immediate relief. Anticholinergics can be useful as an adjunct in certain situations but are not typically the first-line option for acute asthma symptoms. Mast cell stabilizers are preventive medications that help reduce inflammation over time but are not effective for rapidly alleviating acute symptoms. Thus, short-acting beta-2 agonists are the appropriate choice for immediate management of sudden asthma symptoms.
