The stress of stressful situations must be minimised whenever possible, and horses should be provided plenty of time to rest and recuperate after races or trips.

Treatment for gastric ulcers in horses usually requires a combination of medications and changes in management. The use of medications such as omeprazole and ranitidine is used to decrease the production of stomach acid and aid in the healing of the tissue that has been damaged. Management changes can include changes to a horse’s diet, feeding schedule, and exercises.

Dexamethasone and Immune System Suppression in Horses

The corticosteroid dexamethasone has potent effects and is typically used to treat horses for many health conditions. One of the most important characteristics of dexamethasone is its ability to reduce the immune system. While this is beneficial in certain circumstances, it could also have negative effects.

How dexamethasone suppresses the immune system

Dexamethasone is a drug that acts by binding to the glucocorticoid receptors found in the body. These receptors are found on various cells, including immune cells. When dexamethasone can bind to these receptors and change gene expression in the immune system, this causes decreased activity of immune cells such as B cells, T cells, and natural killer cells.

The inhibition of the immune system via dexamethasone may have numerous positive effects. For instance, it may aid in reducing swelling and inflammation in the body. This can be beneficial for conditions like allergies or arthritis. However, the deficiency of the immune system may be detrimental, especially if it is long-lasting or severe.

Risks Associated With Immune System Suppression

One of the most significant dangers associated with suppressing the immune system in horses is the increased vulnerability to infections. If the immune system weakens, the body’s capacity to combat infections diminishes. This can increase the risk of developing bacterial, fungal, viral, and bacterial infections. Horses receiving Dexamethasone must be closely monitored for any signs of infection, and any infections must be treated immediately.

In addition to a higher chance of contracting infections, the immune system’s suppression can also cause delayed healing of wounds. The immune system plays a crucial role in healing wounds, and if it is suppressed, the process may be slowed or even impaired. Horses taking Dexamethasone must be closely monitored for indications of wound healing delay, and any wounds must be treated immediately.

Managing the Risks of Immune System Suppression

While suppression of the immune system is a risk that could be posed by using dexamethasone, there are steps to take to mitigate this risk. The horses receiving Dexamethasone must be closely monitored for any signs of infection, and any infections must be treated immediately. Horses with a history of infections or weak immune systems might not be suitable candidates to receive dexamethasone treatment.

It is also crucial to choose the most effective dose and reduce the length of treatment as much as possible. Excessive or prolonged use of dexamethasone may increase the chance of immune system suppression and other adverse effects. In certain instances, alternative treatments that don’t inhibit the immune system might be available.
