SAFETY

Contraindications: Do not administer VETMEDIN in cases of hypertrophic cardiomyopathy, aortic stenosis, or any other clinical condition where an augmentation of cardiac output is inappropriate for functional or anatomical reasons.

Do not administer VETMEDIN to dogs with Stage A or B1 preclinical MMVD due to the risk of cardiac pathology associated with exaggerated hemodynamic responses to VETMEDIN.

 

Warnings: Only for use in dogs with Stage B2 preclinical Myxolmatous Mitral Valve Disease (MMVD) or clinical evidence of Congestive Heart Failure (CHF) due to MMVD or Dilated Cardiomyopathy (DCM). At 3 and 5 times the recommended dosage, administered over a 6-month period of time, pimobendan caused an exaggerated hemodynamic response in the normal dog heart, which was associated with cardiac pathology. Keep VETMEDIN in a secure location out of reach of dogs, cats, and other animals to prevent accidental ingestion or overdose.

 

Human Warnings: Not for use in humans. Keep this and all medications out of reach of children. Consult a physician in case of accidental ingestion by humans.

 

Precautions: The safety of VETMEDIN has not been established in dogs with asymptomatic heart disease or in heart failure caused by etiologies other than myxomatous mitral valve disease (MMVD) or dilated cardiomyopathy (DCM). The safe use of VETMEDIN has not been evaluated in dogs younger than 6 months of age, dogs with congenital heart defects, dogs with diabetes mellitus or other serious metabolic diseases, dogs used for breeding, or pregnant or lactating bitches.

 

Adverse Reactions: The most common side effects reported in field studies were poor appetite, lethargy, diarrhea, dyspnea, azotemia, weakness, and ataxia.

Give your Stage B2 Preclinical MMVD and your Stage C&D CHF Patients more life to love

  • VETMEDIN products have a dual mode of action, relaxing the blood vessels carrying blood to and from the heart, and improving heart muscle contractility to help the heart work more efficiently.

 

  • In a clinical study, dogs treated with VETMEDIN in preclinical Stage B2 demonstrated an average of up to 15.6 months of prolonged, symptom-free life compared to dogs treated with a placebo.1

 

  • In a clinical study, dogs in CHF due to MMVD treated with VETMEDIN products at the onset of clinical signs survived almost twice as long from the start of treatment as those treated with an ACE inhibitor.3

 

  • Dogs treated with VETMEDIN products from the onset of clinical signs of CHF also required less therapy to maintain quality of life as those treated with an ACE inhibitor.5

Catch It Early,
 Make a Difference

Heart disease is common—10% of dogs that are presented in primary care will be diagnosed with heart disease in their lifetime.4,7 Early intervention can help patients delay the onset of symptoms if diagnosed in the preclinical Stage B2 of MMVD or extend survival time, with a better quality of life, if treated early in Stage C CHF due to MMVD or DCM.1-4

 

Stage B2 Preclinical:
According to the 2019 American College of Veterinary Internal Medicine (ACVIM) consensus guidelines, Stage B2 MMVD refers to asymptomatic dogs that have more advanced cardiac remodeling that meet clinical trial criteria used to identify dogs that should benefit from initiating treatment to delay the onset of heart failure.6

 

The ACVIM consensus statement recommends the following diagnostic criteria to confirm Stage B2 MMVD:6

  • Murmur intensity ≥3/6
  • Echocardiographic left atrium/aorta ratio (LA/Ao ratio) in the right-sided short axis view in early diastole ≥1.6
  • Left ventricular internal diameter in diastole, normalized for body weight (LVIDDN) ≥1.7
  • Breed-adjusted radiographic vertebral heart score (VHS) >10.5

 

If only radiographic examination is possible, cardiomegaly may be diagnosed in cases where the VHS ≥11.5 and the vertebral left atrial size (VLAS) ≥3.0.6, 7 If radiographic cardiomegaly does not meet both of these criteria, an echocardiogram should be performed prior to the initiation of therapy.6

 

Signs and Symptoms of Congestive Heart Failure: 
The ACVIM recommends looking for the following clinical signs and symptoms.6, 10

  • Tachypnea
  • Restlessness
  • Respiratory distress
  • Persistent cough
  • Reluctance to exercise or play
  • Lack of stamina
  • Ascites

Common Acquired Heart Conditions

Myxomatous Mitral Valve Disease

 

  • A heart condition where the degeneration of the mitral valve prevents closure of the valve leaflets, allowing blood to leak back into the left atrium.
  • A common type of chronic valvular heart disease (CVHD), MMVD accounts for roughly 75% of canine heart diseases.2, 11
  • Canine MMVD primarily affects older, small to medium size dogs, although any dog can be affected. Common at-risk breeds include: Cavalier King Charles Spaniel, Pekingese, Pomeranian, Miniature Pinscher, Boston Terrier, Miniature Poodle, Toy Poodle, Chihuahua.

Three Most Predictive Indicators of Disease Progression

When you are on the lookout for CHF in a Stage B2 patient, there are three early predictors that indicate if, or when, heart disease will progress into Stage C heart failure. Paying attention to these indicators can help extend your patient’s survival time:14

 

1. Increased heart size, demonstrated by Vertebral Heart Score (VHS)

2. Increased Heart Rate (HR)

3. Increased Respiratory Rate (RR) and increased Resting Respiratory Rate (RRR), which are the most predictive signs and can be monitored at home by the pet owner with the My Pet’s Heart2Heart app

VETMEDIN (pimobendan) brand vs Compounded Pimobendan

  • VETMEDIN is the only brand approved by the FDA that includes both tablet and liquid formulations to manage dogs starting at Stage B2 preclinical MMVD through CHF.

 

  • Compound manufactured preparations using bulk substances are not equivalent to the FDA approved products. The FDA does not evaluate the safety of compounded formulations.

 

  • Without an appropriate formulation process, compounded products may be manufactured with unknown GI absorption properties and uncertain efficacy.

Studies & Resources

Survival Time           
The largest clinical study of dogs with CHF ever conducted found that the survival time of dogs treated with VETMEDIN (pimobendan) nearly doubled compared to those treated with an ACE inhibitor.3

 

Specialty Guidelines            
The ACVIM’s official website has continuing education resources, certification trainings, information on consensus guidelines, and more. 

 

Predictive Factors of CHF           
The third EPIC Study publication reinforces the value of clinical and radiographic variable assessment in dogs with MMVD and specifically RR and RRR as indicators of impending or incipient CHF.14

 

Quality of Life           
In this study, VETMEDIN improved quality of life of dogs in heart failure while decreasing the mean heart size in patients treated for the full 56 days.2

 

Preclinical Variables in Stage B2           
The EPIC study was a prospective, multi-center, double-blinded, randomized, placebo-controlled study. It compared the changes that occurred as dogs with preclinical MMVD and cardiomegaly developed CHF, compared to dogs that did not develop CHF.1

FAQs

Is VETMEDIN® (pimobendan) safe for use in all dogs?

VETMEDIN should not be given in case of hypertrophic cardiomyopathy, aortic stenosis, or any other clinical condition where an augmentation of cardiac output is inappropriate for functional or anatomical reasons.

 

The safety of VETMEDIN has not been established in dogs with asymptomatic heart disease or in heart failure caused by etiologies other than MMVD or DCM. The safe use of VETMEDIN has not been evaluated in dogs younger than 6 months of age, dogs with congenital heart defects, dogs with diabetes mellitus or other serious metabolic diseases, dogs used for breeding, or pregnant or lactating bitches.

 

What happens if a pet owner forgets to give one of the VETMEDIN daily doses?

Instruct the pet owner to wait until the next scheduled dosing time and resume the normal twice-daily (every 12 hours) pattern of dosing.

 

What should be done in an acute overdose situation?

There is no specific antidote for an overdose of VETMEDIN. Contact 866-638-2226 for technical support.

 

What should be done if a dog vomits shortly after dosing?

Please call Boehringer Ingelheim Veterinary Technical Solutions to report the suspected adverse event at 866-638-2226. Some dogs in clinical trials experienced transient mild vomiting that resolved after a few doses. If vomiting is severe or persistent, discontinue the medication and call Boehringer Ingelheim Veterinary Technical Solutions at 866-638-2226.

 

Is there a maximum duration of administration for VETMEDIN?

No, there is no limit on the period of time VETMEDIN can be administered to a patient.8, 9

 

What is the Cardiac Education Group?

The Cardiac Education Group (CEG) is a group of board-certified veterinary cardiologists from both academia and private practice that offers independent recommendations for the evaluation and treatment of canine heart disease. The group provides resources and information on the diagnosis, treatment, and management of heart disease and heart failure in dogs to promote early detection and diagnosis with greater accuracy and confidence.

 

Visit the CEG website at www.cardiaceducationgroup.org. You’ll find many free tools to help simplify canine heart disease diagnosis and treatment.

 

What is myxomatous mitral valve disease (MMVD)?

As its name suggests, MMVD affects the mitral valve located on the left side of the heart between the atrium and the ventricle. MMVD is a slowly progressive disease in which the mitral valve deteriorates over time. Normally, when they close, heart valves form a perfect seal ensuring that blood flows in the right direction through the heart. The function of the mitral valve is to channel blood from the left atrium into the left ventricle. However, when MMVD occurs, the distortion of the mitral valve leaflets results in an imperfect seal and allows blood to “leak” backward into the atrium as the ventricle contracts.

 

What is the difference between MMVD and DCM in dogs?

MMVD and DCM are the 2 most common causes of canine heart disease with MMVD accounting for about 75% of canine cases of heart disease seen in veterinary clinics in the US.2, 11 MMVD tends to have a long preclinical phase lasting from months to years and is a slow-progressing degenerative disease1 that damages heart valve leaflets.

 

DCM has a preclinical phase as well but, unlike MMVD, tends to progress rapidly. DCM is a disease of the heart muscle that causes loss of myocardial contractility. DCM is a significant cause of morbidity and mortality in certain breeds.15 In North America, the Doberman Pinscher is the most commonly affected breed.15

 

Both MMVD and DCM may ultimately lead to CHF in dogs and require prompt treatment at the first appearance of clinical signs to help improve quality of life and extend survival time.
