Which inhaler is commonly used during an asthma incident for immediate relief?

Salbutamol is the commonly used inhaler for immediate relief during an asthma incident because it is classified as a short-acting beta-agonist (SABA). This medication works quickly, typically within minutes, to relax the muscles around the airways, allowing for easier breathing. It’s particularly effective for treating acute asthma symptoms or exacerbations, making it the go-to choice for quick relief.

In contrast, Primatene Mist, while also used for asthma, is less commonly recommended today due to safety concerns and reduced availability. Budesonide is a corticosteroid that helps to control inflammation but is not designed for immediate relief; it's typically used for long-term management of asthma. Cromolyn sodium is classified as a mast cell stabilizer and is used mainly for prevention rather than immediate response during an asthma attack. Thus, salbutamol stands out for its rapid action and effectiveness in urgent situations.
