Seizure Rescue Medications: The Options Continue to Expand

While attending the recent American Epilepsy Society Meeting in December, I had many discussions about seizure rescue medications that really exemplified to me how many options now exist for patients.

What are seizure rescue medications?

Seizure rescue medications are meant to be used outside of daily anti-seizure medications to treat cluster seizures or prolonged seizures. The patient’s neurologist should prescribe these medications with well-defined instructions on when it is appropriate to utilize the rescue medication, based on the individual patient’s seizure patterns. Important discussions with the neurologist should include:

  • When to administer the seizure rescue medication
  • How to administer the seizure rescue medication
  • Side effects and risks associated with the seizure rescue medication
  • How often the seizure rescue medication can be given safely
  • When to seek additional medical care after using the seizure rescue medication

It is also important to make sure your loved one’s Seizure Action Plan is up-to-date with the current seizure rescue medication details after discussing with the neurologist. If you need additional help building a Seizure Action Plan, visit seizureactionplans.org.

What seizure rescue medication options are available?

There are several types of rescue medications that can be administered in different ways. The decision process for each patient will depend on which medication works the best for them as well as a consideration of the routes of administration. Some commonly used options are listed below.

  • Diastat is a rectally administered gel formulation of diazepam approved for patients 2 years and older. Diazepam rectal gel comes in a syringe that is pre-filled and dialed to the correct dose for the individual patient. The pharmacist should dial in the correct dose, but it is always a good idea to double-check prior to administration.
  • Valtoco is an intranasal spray formulation of diazepam approved for patients 6 years and older, and is currently being studied in a clinical trial for patients aged 2 to 5 years. Valtoco comes pre-dosed in a one-time use device that allows for administration directly inside the nostril.
  • Nayzilam is an intranasal spray formulation of midazolam approved to treat seizure clusters in patients 12 years and older. Nayzilam comes pre-dosed in a one-time use device that allows for administration directly inside the nostril.
  • Lorazepam can be administered buccally (between the teeth and gums).

Some families work with their loved one\’s health care team to utilize other options that are more appropriate for their situation. Your neurologist can help determine what medication might be most appropriate to meet their needs.

New seizure rescue medication options are in clinical trials.

As mentioned above, Valtoco is currently being investigated in a trial sponsored by Neurelis for patients aged 2 to 5 years. For information on the trial visit clinicaltrials.gov or contact cguerra@neurelis.com.

UCB is sponsoring a trial for a new type of seizure rescue medication called Staccato Alprazolam for patients aged 12 years and older with stereotypical, prolonged seizures. The medication is alprazolam, a benzodiazepine (like diazepam, midazolam, and lorazepam) used at a low dose and combined with the Staccato device that allows the medication to be inhaled with a passive breath from the patient. The big difference between Staccato Alprazolam and currently available seizure rescue medications is the much quicker time-to-action following administration. The Phase 2 trials took place in a hospital setting, finding that the mean onset of action for stopping seizure activity was 30 seconds. Given the importance of stopping seizures quickly, this could be a very important benefit. The now enrolling Phase 3 trials will be testing the use of Staccato Alprazolam in the home setting. If you are interested in participating in the trials, visit clinicaltrials.gov for more info or contact UCBCares@ucb.com.
