Treatment & management

Bronchodilators (a drug that dilates the bronchi to increase airflow) can open up the lower airways, while mucolytic drugs may loosen mucus. Some horses may need a course with glucocorticoids – these drugs stop the hypersensitivity reaction. Many of these can be given by injection, orally or inhaled. Inhalation therapy may be a better long-term option as the drug dose is targeted to the respiratory system, minimising side effects. Some horses benefit from antibiotics if the airway mucus has allowed for bacterial growth. It’s important to minimise allergen exposure, so horses with SPAOPD will benefit from staying inside in a dust-free space when it’s hot and when the pollen count is high.
