Trilostane for Dogs: A Comprehensive Guide

Introduction

Trilostane is a medication commonly used to treat Cushing's disease in dogs, a condition characterized by excessive production of the hormone cortisol. This article will provide a comprehensive overview of trilostane, including its mechanism of action, dosage information, potential side effects, and administration guidelines.

Understanding Trilostane

Trilostane belongs to a class of drugs known as steroidal synthesis inhibitors. It works by disrupting the production of cortisol in the adrenal glands, thereby reducing its levels in the body. Specifically, trilostane inhibits the enzyme 17α-hydroxylase, which is involved in the production of cortisol.

Dosage and Administration

The optimal dosage of trilostane for dogs varies depending on their weight and individual response to the medication. Generally, the starting dose is 1-2 mg per kg of body weight, given once or twice daily.

Veterinarians may adjust the dosage based on the dog's clinical signs, blood test results, and any side effects experienced. It is important to follow the veterinarian's instructions carefully and administer the medication as prescribed.

Side Effects

Trilostane can cause side effects in some dogs. The most common side effects include:

• Gastrointestinal upset: vomiting, diarrhea, loss of appetite
• Lethargy
• Weakness
• Polyuria (increased urination)
• Polydipsia (increased thirst)

Less common side effects can include:

• Adrenal insufficiency
• Liver damage
• Neurological problems

Administration Guidelines

Trilostane should be administered with food to reduce the risk of gastrointestinal upset. It is recommended to give the medication at the same time each day to maintain consistent blood levels.

Dogs receiving trilostane should be monitored closely for side effects, particularly during the initial stages of treatment. Periodic blood tests may be necessary to check the dog's adrenal function and overall health.

Effective Strategies

To minimize the risk of side effects and maximize the benefits of trilostane, consider these strategies:

1. Start with a low dose: Gradually increase the dosage over time as needed.
2. Administer with food: Reduce gastrointestinal upset by giving the medication with food.
3. Monitor your dog closely: Observe for any changes in behavior, appetite, or urination patterns.
4. Follow veterinarian's instructions: Adhere to the prescribed dosage and follow-up guidelines.

How to Step-by-Step Approach

1. Consult your veterinarian: Discuss your dog's symptoms and obtain a diagnosis of Cushing's disease.
2. Start low, go slow: Begin with a low dose of trilostane and gradually increase it over time.
3. Check blood tests: Monitor your dog's adrenal function and overall health through regular blood tests.
4. Observe for side effects: Pay attention to any changes in your dog's behavior or health.
5. Maintain a dialogue with your veterinarian: Communicate any concerns or changes you observe.
