Atrovent Hfa is a bronchodilator that relaxes muscles in the airways and increases the flow of air to the lungs. It is used to prevent bronchospasm or narrowing of the airways in the lungs in people with emphysema, bronchitis and chronic obstructive pulmonary disease abbreviated as (COPD).
Atrovent Hfa is a medicine used in the prevention of bronchospasm - particularly for patients with chronic obstructive pulmonary disease (COPD), bronchitis, and emphysema. Again, Atrovent Hfa is used for preventative purposes and may not be used in the treatment of acute bronchospasm attacks.
The active ingredient of Atrovent Hfa - ipratropium bromide - is an anticholinergic drug. Acetylcholine is, in contrast, a cholinergic agent, being responsible for muscle contraction and spasm. Atrovent Hfa blocks the effects of acetylcholine, thereby reducing these spasms.
Atrovent Hfa is only available via the inhalational route. It has a short half-life of 2 hours, meaning 75 percent of the drug has left the body after 4 hours. Common side effects with Atrovent Hfa include cold-like symptoms, nausea, constipation, dry mouth, and headache.
