Introduction

Ventolin Hfa, also known as albuterol, is a short-acting bronchodilator medication, and is widely used to treat and prevent wheezing due to asthma, chronic obstructive pulmonary disease (COPD) and other respiratory diseases. It works by helping open the airways in the lungs to make breathing easier. It can also be used to prevent exercise-induced bronchospasm.

Uses

Ventolin Hfa medications are used to treat and prevent asthma and other similar respiratory problems like wheezing, shortness of breath and chest tightness.

Ventolin Hfa works by stimulating the Beta2 receptors of the lungs, which relaxes the smooth muscles of the airways. This allows the airways to open up and allows more air into the lungs.
