General Vaccine Information. Specific Vaccines. New Category. Pet Connection. Pet Corner. Last Update Posted : January 12, Study Description. Currently, there was no evidence-based therapy such as mechanically assisted circulatory support available in China.
The investigators found glucocorticoid treatment such as prednisone could improve cardiac performance, potentiate renal responsiveness to diuretics in such patients. Therefore, it could be used as bridge therapy to help ACE inhibitors or beta blocker titration. With its help, most of the patients with stage D heart failure could be titrated to higher dose of ACE inhibitors and beta blockers during hospitalization.
However, the efficacy of long-term, low-dose of prednisone use in such patients with limited life expectancy remain unclear. Therefore, the investigators designed this study to observe whether putting low-dose of prednisone on the patients with stage D heart failure for long term could further improve their survival. All patients will receive prednisone treatment during hospitalization and receive maximum tolerated guideline-directed medical therapy GDMT.
After discharge from hospital, the patients will be randomized to receive long-term, low-dose prednisone treatment or standard GDMT. Drug Information available for: Prednisone. FDA Resources.

Prednisone is sometimes used interchangeably with a similar drug called prednisolone. Prednisone is converted into prednisolone in the liver. Because of this, veterinarians sometimes prescribe prednisolone over prednisone to reduce hepatic stress in dogs with liver disease. If you've ever taken a steroid drug, then you probably experienced some undesirable side effects. Most people report extreme thirst and hunger as well as mood changes and trouble sleeping.
Prednisone side effects vary from dog-to-dog and dose-to-dose, but they tend to be similar to side effects in people. Most dogs on prednisone will have increased thirst and urination along with a voracious appetite that can lead to weight gain.
Restlessness and panting may also occur. These signs can gradually improve as the dog adjusts to the medication and should cease after the drug is stopped. It's important to provide fresh water to dogs on prednisone, but avoid letting them drink excessive amounts at one time because it may cause regurgitation or vomiting.
More drinking equals extra pee, so make sure your dog gets additional opportunities to go outside and relieve herself.
Your dog will probably be seriously hungry and begging for food, but resist the urge to feed extra food as it may cause weight gain. Consider feeding smaller, more frequent meals or offering your pup some low-calorie treats throughout the day. Long-term use or high doses may lead to more serious issues.
Prednisone can impact the gastrointestinal tract, causing vomiting, diarrhea, and GI ulceration or bleeding. Dogs may develop a pot-bellied appearance as well as poor haircoat or loss of hair, all signs of Cushing's syndrome. Over time, prednisone may cause elevation of liver enzymes that leads to liver dysfunction. Contact your veterinarian right away if you notice significant side effects, Your vet may adjust the dose or switch to another medication.
In addition to treating a variety of conditions, prednisone has a very wide dosage range. The appropriate dose depends on the weight of the dog and the specific condition being treated. In general, vets try to use the lowest effective dose for the shortest time possible in order to avoid complications and side effects.
Your veterinarian will determine the appropriate dose for your dog and provide instructions for proper administration. Prednisone is usually given to a dog orally in the form of a pill , but liquid forms are available for smaller dogs or very low doses. Dogs are often started on moderate to high doses that are gradually tapered down until they can be stopped. Some conditions can be treated with a short course of prednisone while others require long-term treatment.
Your veterinarian may recommend lab testing to monitor the effects of prednisone on your dog's body, especially with long-term treatment. This will allow the vet to see small changes and adjust the dose before complications occur.

Prednisone available in 1 mg, 2. Prednisone and prednisolone are members of the glucocorticoid class of hormones. This means they are steroids, but unlike the anabolic steroids that we hear about regarding sports medicine, these are catabolic steroids.
Instead of building the body up, they are designed to break down stored resources fats, sugars and proteins so that they may be used as fuels in times of stress. Glucocorticoid hormones are produced naturally by the adrenal glands to prepare us metabolically for physical exercise and stress. Cortisone would be an example of a related hormone with which most people are familiar.
Despite the body's natural use for glucocorticoids, we rarely use these hormones for their influences on glucose and protein metabolism, although sometimes we do.
Instead, we use them mostly because they are also the most broadly anti-inflammatory medications available. On top of that, at higher doses they are not just anti-inflammatory but actually immune-suppressive. Their uses fit into several groups:. Prednisone is activated by the patient's liver to prednisolone. In general, these medications are considered interchangeable in dogs but cats seem to have less efficient activation mechanisms. These factors, plus general availability issues with manufacturers, have contributed to recent increases in the use of prednisolone over prednisone.
Prednisone and prednisolone have activity in the kidney that leads to conserving salt. The increased salt retention could be a problem for patients with congestive heart failure. Prednisone and prednisolone are commonly used for several weeks or even months at a time to get a chronic process under control.
The dose should be tapered to an every other day or less schedule once the condition is controlled because that body will perceive these hormones and not produce any of its own.
In time, the adrenal glands will atrophy so that when the medication is discontinued, the patient will be unable to respond to any stressful situation. A blood sugar crisis can result. Using the medication every other day allows the body's own adrenal glands to remain active.
Any latent infection can be unmasked by prednisone use. Feline upper respiratory infections would be a classical example. When a cat recovers clinically, the infection simply goes dormant. Glucocorticoid use could bring the infection out again. Upper respiratory infections and even bladder infections are usually readily controlled. If there is a more serious infection, such as an internal fungal infection, corticosteroids could bring it out, leading a potentially life-threatening situation.
Glucocorticoids will interfere with intradermal skin testing for allergy as well as with thyroid function testing. If a more serious infection, such as an internal fungal infection, is present, corticosteroids could bring it out leading to a potentially life-threatening situation.
Glucocorticoid hormone use can be irritating to the stomach and GI tract at higher doses. Bleeding and ulceration can occur. If your pet becomes listless, loses appetite, develops vomiting, or develops a dark tarry stool, inform your veterinarian immediately. It is possible for a patient on the verge of developing diabetes mellitus to be tipped into a diabetic state.
Glucocorticoids can increase appetite and are sometimes used for their appetite-stimulating properties. They also raise blood cholesterol levels and increase circulating fats. Ulceration could occur. The goal in therapy with glucocorticoids is to find the lowest effective dose. Prednisone and prednisolone are considered to be intermediate-acting steroids, meaning that a dose lasts about a day or a day and a half.
After two weeks or more of use, it is important to taper the dose to an every other day schedule so as to keep the body's own cortisone sources able and healthy.
The same salt retention that accounts for the excessive thirst and urination may also be a problem for heart failure patients or other patients who require sodium restriction. When doses become immune-suppressive higher doses or use becomes chronic longer than four months at an every other day schedulethe side effects and concerns associated become different. In these cases, monitoring tests may be recommended or, if possible, another therapy may be selected.
If a dose is accidentally skipped, do not double up on the next dose. Do not abruptly discontinue this medication; expect a tapering schedule.

orally administered intermediate-acting glucocorticoids (prednisone) could predispose dogs to progression of heart disease or congestive heart failure. Long-term prednisone/prednisolone use is associated with increased risk for latent bladder infection, especially in dogs. The investigators found glucocorticoid treatment such as prednisone could improve cardiac Heart Failure Hyperuricemia, Drug: prednisone, Phase 2 Phase 3. A prednisone overdose in dogs can cause itching, weakness, loss of hearing, depression, anxiety, increased blood pressure, heart problems, and seizures. That's. To further complement this finding, the authors found that heart rates in the treatment group decreased during treatment with prednisone. Congestive Heart Failure in Dogs. More Information.Reviewed and updated for accuracy on July 10, , by Dr. Dilated cardiomyopathy DCM is a disease of the heart muscle that is characterized by an enlarged heart that does not function properly.
In most cases of DCM in dogs, the ventricles lower chambers of the heart become enlarged, though some cases also involve enlargement of the atria upper heart chambers.
With DCM, the muscle wall of the heart becomes thinner, causing it to lose the ability to pump blood to the rest of the body. If left untreated, the compromised heart muscle eventually becomes overwhelmed by the increased fluid volume, resulting in congestive heart failure CHF.
In some cases, dogs with preclinical DCM prior to the appearance of symptoms may be given a questionable diagnosis if they appear to be in fine health. On the other hand, a thorough physical exam can reveal some of the subtle symptoms of DCM, such as:.
Slow capillary refill time in the mucous membrane tissues e. The incidence of DCM in dogs increases with age and usually affects dogs that are years old. Although the definitive cause of DCM in dogs is unknown, the disease is believed to have several factors, including nutrition, infectious disease and genetics.
Nutritional deficiencies related to taurine and carnitine have been found to contribute to the formation of DCM in certain breeds, such as Boxers and Cocker Spaniels.
In addition to a thorough physical examination, certain medical tests are needed to confirm a diagnosis of DCM in dogs and rule out other diseases.
Radiographic X-ray imaging may reveal that the dog has an enlarged heart as well as fluid in or surrounding the lungs.
An electrocardiogram EKG may reveal an arrhythmia or irregular heartbeat or ventricular tachycardia abnormally rapid heartbeat. In some cases, a hour EKG Holter monitor may be required to fully characterize abnormal heart activity. An ultrasound of the heart, known as an echocardiogram, is required to definitively diagnose DCM. In the case of DCM, an echocardiogram will reveal enlargement of one or more heart chambers, along with decreased contractile ability of the heart muscle. A diuretic may also be administered to decrease fluid accumulation in various tissues, and a vasodilator may be given to dilate the blood vessels and improve circulation.
Except in cases where a dog is severely affected by the disease, long-term hospitalization should not be necessary. Depending on the underlying cause of disease, DCM in dogs may be progressive and have no cure. Therefore, long-term prognosis is relatively poor for dogs that have clinical signs of heart failure.
Frequent follow-up examinations are typically recommended to assess progress of the disease. Assessment may include thoracic radiographs, blood pressure measurement, EKG and blood work. Your veterinarian will counsel you on your pet's prognosis based on the progression of the disease at the time of diagnosis. In general, dogs with this condition are given months to live. Doberman Pinschers tend to be more severely affected by this disease and will generally not survive longer than six months after the diagnosis is made.
In this case, your veterinarian can advise you on treatment options in order to keep your dog as comfortable as possible.
