What is Prednisolone?
Properties and Description
Prednisolone is a man-made corticosteroid that fights inflammation. It’s easier for horses to absorb than oral prednisone. While it can be given orally, the small tablet sizes make it hard to use. Instead, veterinarians often recommend oral dexamethasone for horses.
The injectable form of dexamethasone is given to horses with breathing problems. It helps them breathe better.
Prednisolone is used to treat many conditions in animals, like inflammation and breathing issues. It’s effective and often prescribed by vets.
It works by affecting how cells behave. It comes in different strengths, like Twist-a-Dose and EZ Dose Micro. It starts working in 1-2 hours.
While it’s usually safe, it can cause side effects like more drinking and eating. Serious issues include stomach problems and diabetes. It’s important not to stop it suddenly.
For horses, the right dose of oral prednisolone is 0.25-1 mg/kg. Short-term use is mostly safe. But long-term use can harm the adrenal glands and cause metabolic problems.
Prednisolone is a key medication for vets. But it’s only for them to use and not allowed in competitions without drugs.
Usage of Prednisolone for Horses
Prednisolone is a synthetic corticosteroid used in equine medicine. It treats inflammatory and immune-related conditions. This medication is given systemically to horses, offering a valuable treatment option for many ailments.
Prednisolone is mainly used to treat Recurrent Airway Obstruction (RAO), or “heaves.” This chronic respiratory disorder is managed with oral prednisolone. It reduces inflammation and improves breathing. Oral prednisolone is more effective and convenient for equine vets.
Prednisolone also helps with other allergic or immune-mediated disorders in horses. This includes skin conditions, inflammatory bowel disease, and autoimmune disorders. Its anti-inflammatory and immunosuppressive properties make it a valuable tool in managing these complex health challenges.
Recent studies have shed light on prednisolone’s pharmacokinetics in horses. The drug is found in measurable amounts in the blood and synovial fluid of horses. Within 3 hours of administration, mean blood levels are 92.655 ng/mL, and synovial fluid levels are 28.44 ng/mL.
| Measurement | Mean Concentration | Standard Deviation |
|---|---|---|
| Blood Concentration | 92.655 ng/mL | 54.95 ng/mL |
| Radiocarpal Joint Synovial Fluid Concentration | 28.44 ng/mL | 20.58 ng/mL |
| Tibiotarsal Joint Synovial Fluid Concentration | 20.33 ng/mL | 15.67 ng/mL |
These findings show prednisolone’s versatility and effectiveness in treating various equine health concerns. It helps with respiratory issues and joint inflammation, making it a valuable tool in equine veterinary care.

Following a vet’s advice is crucial to avoid serious issues with prednisolone precautions in horses. Knowing the side effects and precautions helps keep horses safe and healthy.
Equine Recurrent Airway Obstruction (RAO)
Prednisolone is key in treating Recurrent Airway Obstruction (RAO) in horses. It was once called heaves or chronic obstructive pulmonary disease (COPD). RAO is a lung disease caused by an allergy to dust and spores. This allergy makes the airways in the lungs swell and fill with fluid, blocking air.
RAO mainly hits horses over 7 years old, with most cases starting at 9-12 years. If both parents have RAO, their offspring are 44% likely to get it. This shows a strong link to genetics.
The Northern Hemisphere sees a big difference in RAO cases, from 2% to 80%. Horses indoors are most at risk. The problem gets worse in winter and spring when barns are poorly ventilated.
Diagnosing RAO involves lung tests, aspiration, and bronchoalveolar lavage. These methods show the inflammation in the airways. X-rays can also show changes in the lungs.
Managing RAO includes changing the environment and using medicines like bronchodilators and corticosteroids. With the right treatment, RAO symptoms can be controlled.
“The first mention of a condition similar to heaves (RAO) dates back to 333 BC, when Aristotle described a condition called ‘heartache’ in horses.”
Types of RAO in Horses
Recurrent Airway Obstruction (RAO), also known as Heaves, is a common problem in horses. It limits their performance. There are two main types: barn-associated RAO and pasture-associated RAO.
Barn-Associated RAO
Barn-associated RAO affects horses kept in stalls and fed hay. They show symptoms when in their stalls, on straw, and eating hay. Removing these factors can help reduce or stop symptoms.
Pasture-Associated RAO
Pasture-associated RAO, or summer heaves, is common in horses on pastures in the Southeast. These horses struggle with breathing in the summer. It’s due to allergens in the pasture.
| Statistic | Value |
|---|---|
| Prevalence of Equine Asthma in North Carolina | Most horses have “Summer-Pasture-Associated” asthma |
| Cost of Systemic Steroids Treatment | Below $50 per month |
| Cost of Aservo Equihaler Initial Treatment | $300 to $400 |
| Initial Cost for Nebulizer Mask Treatment | $1,000 |
| Cost of Alpha 2 Macroglobulin Nebulization Therapy | Approximately $1,100 for 10 treatments |
| Cost of Apoquel Tablet Treatment | Around $10 per day initially, decreasing to $5 per day |
| Cost of Alpha 2 Macroglobulin Product | Roughly $1,100 for 10 treatments |
| Cost of Nebulizer Cup Replacement | About $80 per cup |
Managing the environment and using the right medicines can help horses with RAO. This way, they can keep competing.
