Zonisade (zonisamide oral suspension 100 mg/5 ml)

(NDC 52652-8001-1)

Product labeling, packaging, and imagery are for representation purposes only.

ZONISADE® (zonisamide oral suspension), 100 mg/5 mL is indicated as adjunctive therapy for the treatment of partial-onset seizures in adults and pediatric patients 16 years of age and older.

The ready-to-use* oral liquid formulation of ZONISADE® eliminates the need for compounding and crushing.
*Shake well before administering.

ZONISADE® can be stored at room temperature and should be protected from light.2

The beyond-use date of ZONISADE® is 30 days after a bottle is first opened.2

Administration and Storage

ZONISADE® is an oral liquid suspension and should be shaken well before every administration.

To administer directly into the mouth, it is important that ZONISADE® be measured with an accurate measuring device. Inform patients that a pharmacist will provide an appropriate device and instructions for measuring the correct dose. A household teaspoon is not an accurate measuring device.

ZONISADE® should be administered once or twice daily with or without food.

No refrigeration is required, as ZONISADE® can be stored at room temperature. It should also be protected from light. Once opened, unused portions should be discarded after 30 days.2

Dosing

The recommended initial dose of ZONISADE® is 100 mg daily. The dosage may be increased by 100 mg daily every 2 weeks to 400 mg daily based on clinical response and tolerability. However, evidence from controlled trials shows no suggestion of increasing response above 400 mg/day. Patients who are tolerating ZONISADE® at 400 mg daily and require further reduction of seizures may be increased up to a maximum dosage of 600 mg daily.

ZONISADE® has a prolonged half-life of 105 hours in red blood cells, which allows for a once-daily dosing regimen and results in steady therapeutic drug levels. This means that if a patient misses a dose, they can resume dosing at the regular schedule without a makeup dose.2

Dosing for Patients Aged 16 Years and Older*
Initial dose 100 mg daily
Beyond 2 weeks May be increased by 100 mg/day every 2 weeks to 400 mg/day†,‡

*Measure with an accurate measuring device. A household teaspoon is not an accurate measuring device.

Based on clinical response and tolerability.

Patients who are tolerating 400 mg/day and require further reduction of seizures may be increased up to a maximum dosage of 600 mg/day. However, evidence from controlled trials shows no suggestion of increasing response above 400 mg/day.

Safety and efficacy in pediatric patients below 16 years of age have not been established. In patients with renal impairment, slower titration and more frequent monitoring may be required.

Oral liquids may help overcome certain barriers to treatment success

  • *ZONISADE® does not have head-to-head data on adherence.
  • A calibrated measuring device is recommended to measure and deliver the prescribed dose accurately. A household teaspoon or tablespoon is not an adequate measuring device. Once opened, unused portion should be discarded after 30 days.2

Why Healthcare Providers Choose Zonisamide For Epilepsy

American Epilepsy Society Guidelines include zonisamide for use in treatment-resistant epilepsy based on Level A, B Recommendations3

  • Level A recommendations are established as effective to reduce seizure frequency
  • Level B recommendations should be considered to reduce seizure frequency

Clinical trials have shown zonisamide to be well tolerated with a good safety profile, which is supported by an excess of 2 million patient-years of clinical exposure4

Long half-life enables once-daily dosing2

  • Patients who miss a dose should resume dosing at their next regularly scheduled dose — no makeup dose needed!
  • After a single-dose administration, renal clearance of zonisamide is approximately 3.5 mL/min. The clearance of an oral dose of zonisamide from red blood cells is 2 mL/min. The elimination half-life of zonisamide in plasma is approximately 63 hours.

adults take several pills each day and nearly half report difficulty swallowing pills5

Pill dysphagia can result in low adherence and treatment failure6

Did you know?

Zonisamide powder can have a bitter taste and disliking taste was considered a barrier to clinical outcomes for adolescent epilepsy patients.7,8

Strategies to improve adherence include pleasant-tasting medications, liquid formulations, and simplified drug regimens (ideally once-daily regimens are preferred).9

Did you know?

Listed by NIOSH as a hazardous drug, zonisamide
presents an occupational hazard for those pregnant, breastfeeding, or trying to conceive.10

NIOSH = National Institute of Occupational Safety and Health

Ready-to-use medications eliminate the need for formulation manipulation, like compounding or crushing solid doses of zonisamide, reducing the risk of hazardous exposure.11

With a sweet, strawberry flavor, ZONISADE® is a ready-to-use* formulation of zonisamide that may help patients who need or prefer an oral liquid alternative.2
