Albuterol is a medication commonly used to treat breathing problems, such as asthma and chronic obstructive pulmonary disease (COPD). It works by relaxing the muscles in the airways, making it easier to breathe. Albuterol is often delivered through an inhaler or nebulizer, allowing for quick relief during asthma attacks or episodes of wheezing. This medication is classified as a bronchodilator, which means it helps open up the air passages in the lungs. Albuterol is generally considered safe when used as directed, but it may cause side effects like increased heart rate or nervousness in some individuals. Always consult a healthcare professional for proper usage.
