Introduction to Albuterol
Albuterol, also known as salbutamol or by the brand name Ventolin, is a widely used medication for treating respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). It belongs to a class of drugs known as bronchodilators, which work by relaxing the muscles in the airways and increasing airflow to the lungs.
How Albuterol Works
Albuterol is a beta-2 adrenergic agonist that targets beta-2 receptors in the lungs, leading to the relaxation of bronchial muscles. This action helps to open up the airways, making breathing easier. The medication typically acts within 15-30 minutes of administration, providing rapid relief from symptoms.
Common Uses
- Asthma management
