Blue asthma inhaler contain short-acting beta-agonists (SABAs), such as salbutamol (albuterol). These medications work by relaxing the muscles around the airways, allowing them to open up and ease breathing. Unlike preventive inhalers, blue inhalers provide immediate relief from acute asthma symptoms, making them indispensable during asthma attacks. Asthma is characterized by inflammation and narrowing of the airways, leading to symptoms such as wheezing, shortness of breath, chest tightness, and coughing. These symptoms can vary in intensity and frequency, often triggered by allergens, physical activity, cold air, or respiratory infections.
