What supplement can I use as a bronchodilator for endurance race horses in a dusty environment? Ahmed
Unfortunately, there are no over-the-counter respiratory supplements with bronchodilator activity. The prescription medications Ventipulmin or Aeropulmin (clenbuterol) are the only FDA-approved solutions to relieve bronchospasm in the horse.That’s not to say there aren’t some very good supplements available to support healthy lung function in horses. One of the best ingredients for respiratory tissue is MSM, with proven antioxidant and anti-inflammatory activity. Vitamin C and N-acetyl cysteine also target the tissues that line the respiratory tract and provide excellent antioxidant support. Other potent antioxidants include Grape Seed Extract, Super Oxide Dismutase and Bioflavonoids, which are active substances in plants that protect cells from oxidative stress. SmartBreathe is an outstanding respiratory supplement that contains these ingredients as well as others, and is available in a highly-palatable pellet form.
There are also some herbs that provide either soothing relief to airways or expectorant-like activity. Look for supplements containing plants such as licorice, garlic, elecampane and marshmallow. Note: some competitive riding associations forbid specific ingredients. If you are showing, please check with your association for rules and regulations.
