What are Long-Acting Beta Agonists (LABAs) primarily used for?

Long-Acting Beta Agonists (LABAs) are primarily used as daily medications for long-term control of asthma and other chronic obstructive pulmonary diseases (COPD). These medications work by relaxing the muscles in the airways, leading to dilation and improved airflow over an extended period, usually around 12 hours or longer. This sustained action makes LABAs suitable for managing symptoms and preventing exacerbations when taken regularly, rather than being used as a quick-relief option.

LABAs are not intended for immediate relief during acute asthma attacks, which is typically managed with short-acting beta agonists (SABAs). They also should not be used solely for short-term relief or for severe asthma cases without an appropriate management plan, as their role is in conjunction with inhaled corticosteroids for controlling symptoms and reducing the frequency of asthma attacks. Using LABAs alone, especially in those with severe asthma, could potentially lead to increased risks, hence their designation for regular, preventive use.
