Product Details

KBroVet®-CA1 is a safe,
reliable treatment for IE

KBroVet-CA1 is the first drug conditionally approved by the FDA for the control of seizures associated with idiopathic epilepsy in dogs. It was developed to provide a consistent and reliable source of potassium bromide, which may help control the seizures associated with IE in canine patients.

The delicious tablet is given once daily, so you don’t have to manage a complex schedule of multiple doses each day. And while it doesn’t make your dog’s seizures go away completely, it can bring some stability to the storm and allow you to get back to a more comfortable daily routine.

What does “conditional approval” mean?

KBroVet-CA1 has received conditional approval from the FDA, so you can trust that it’s a safe and reliable choice for your dog.

Conditional approval means that a product has been proven to be safe and has a reasonable expectation of effectiveness when used according to the label. This provides a faster timeline for products to be legally available, giving veterinarians more treatment options for their patients. The sponsor will continue to collect evidence of effectiveness needed for the product to receive full approval.

It is a violation of Federal Law to use this product other than as directed in the labeling. Learn more about conditional approval at

Reasonable expectation of effectiveness study of KBroVet®-CA1

Determination of Success

KBroVet-CA1 has received conditional approval for the control of seizures associated with idiopathic epilepsy in dogs based on the results of a retrospective study that was performed to evaluate the safety and efficacy of KBr (potassium bromide) for the treatment of idiopathic epilepsy in dogs (data on file).

Determination of Success

  • The sponsor evaluated the medical records of 51 client-owned dogs that were previously treated with KBr to control their idiopathic epilepsy.
  • Effectiveness was evaluated by comparing the 30-day period before initial treatment with KBr and the 30-day period of steady state KBr dosing using these criteria:
    • Seizure counts – decrease of ≥50%
    • Seizure event days per month – decrease of ≥50%
    • Seizure severity scores – decrease or no change
  • Overall reasonable expectation of effectiveness was achieved if >50% of all cases achieved a “success” score for all three variables.

Study Results

As the sole antiepileptic, KBr achieved 67% overall treatment success in all three categories:

Seizure Counts

70% (19/27) were defined as treatment successes

Seizure Event Days Per Month

67% (18/27) were defined as successes by either decreasing or showing no change

Seizure Severity

93% (25/27) were defined as successes by either decreasing or showing no change

Potassium bromide is the active ingredient in KBroVet®-CA1

Potassium bromide is a well-known choice for long-term control of seizures associated with idiopathic epilepsy in dogs.2  The mean elimination half-life of potassium bromide is 21 days.1

The science: Potassium bromide is thought to exert its antiepileptic activity by passing through the neuronal chloride ion channels, thereby hyperpolarizing neuronal membranes, raising the seizure threshold, and stabilizing neurons against excitatory input from epileptic foci.3

Your daily reality: The active ingredient calms the neurons in your dog’s brain cells, which means your dog experiences fewer seizures.

Dosage & Administration

Dosage & Administration

Your veterinarian will determine the best daily dose for your dog. The total recommended daily dosage range for oral administration is 25–68 mg/kg (11–31 mg/lb) of body weight. The dosage of KBroVet-CA1 should be adjusted based on monitoring of clinical response of the individual patient. KBroVet-CA1 may be dosed with or without food.4 Use of an initial loading dosage regimen may be considered on an individual patient basis, balancing the time required to achieve a therapeutic response while minimizing side effects.


Dogs receiving KBroVet-CA1 should be carefully monitored when changing diets, administering chloride-containing intravenous fluids, and administering concurrent medications. Careful monitoring is important in dogs that have a condition that may cause difficulty maintaining electrolyte balance.

  • Animals with decreased renal function may be predisposed to bromide toxicosis.
  • Some dogs may experience epileptic episodes that are unresponsive or refractory to KBr monotherapy and KBr alone may not be adequate for control of seizures for every dog with idiopathic epilepsy.
  • The safe use of KBroVet-CA1 has not been evaluated in dogs that are intended for breeding, or that are pregnant or lactating. The safe use of KBr in neonates and young animals has not been established.
  • Reproductive effects of KBr have been reported in other species.
  • In dogs, ataxia, diarrhea, hematochezia, excessive salivation, shivering, skin lesions, stupor progressing to coma, and death have been reported.
