 What is Cardisure used for?

Cardisure is used in the treatment of heart failure in dogs. Heart failure can occur for a number of reasons and the medication required depends on the underlying cause. The active ingredient in Cardisure, pimobendan, is used in cases of dilated cardiomyopathy where the heart is enlarged or in cases of valvular insufficiency, where the valves in the heart leak and blood flow can be disrupted. Cardisure can be used alone but in many cases will be combined with other heart medications such as frusemide. Use of Cardisure has been shown to improve both quality of life and life expectancy in dogs with heart failure.

 Further Information about Cardisure

Cardisure contains the active ingredient pimobendan. Cardisure is used to treat cases of congestive heart failure where the underlying cause is a dilated heart, known as dilated cardiomyopathy or where the cause is due to a leaking heart valve, also called valvular insufficiency. Cardisure comes as round, light brown, flavoured tablets in a range of sizes. Cardisure comes as 1.25mg, 2.5mg, 5mg and 10mg tablets which are scored so that they can be divided for ease of accurate dosing and are also flavoured to make administration easier. Cardisure is classed as a POM-V which means that it can only be obtained from your vet or with a prescription from them.

Pimobendan, the active ingredient in Cardisure, works by causing the heart to pump faster and more strongly which increases the oxygen delivery to the rest of the body. It does this by increasing the sensitivity of the heart muscle to calcium.

Cardisure is best absorbed by the body if it is given on an empty stomach, this is called the drug’s bioavailability.  It is therefore best to give Cardisure an hour before food. Cardisure can have some side effects but these are generally mild and often dose dependant so can often be resolved by simply lowering the dose. These include pets going off their food, becoming lethargic, vomiting or having diarrhoea. If you suspect that your pet is having any side effects from Cardisure then contact your vet for advice.

Further Information about Dosage and Administration of Cardisure

Cardisure is given orally in tablet form. As mentioned above, the tablets come in several sizes so that accurate doses can be given. The tablets are flavoured and scored so that they can be divided into quarters if needed. The dose of Cardisure that your pet needs will depend on their weight so weigh them regularly. Cardisure should be administered on an empty stomach, around an hour before food as it is absorbed much better by the body in that situation.

There is a dose range for Cardisure so that the dose can be altered depending on the severity of the disease. The range is 0.2-0.6mg of the active ingredient, pimobendan, per kilogram of bodyweight per day. This total dose should be divided into two equal doses and given 12 hours apart. Your vet is likely to start your pet at the lower end of the dose rate and then if there is no response to treatment or if the heart disease worsens then there is scope to increase the dose of Cardisure.

Care should be taken in administering Cardisure to patients with pre existing liver disease as pimobendan is metabolised in the liver. Animals who have diabetes should also be closely monitored when being given Cardisure as it can cause insulin release which will interfere with the treatment of diabetes. The safety of Cardisure has not been assessed in pregnant or lactating bitches so in cases where these animals may require treatment for heart disease, a thorough analysis of the risks and benefits should be done.
