About ZONISADE™ (Zonisamide Oral Suspension)

Zonisamide Structure

• API-Zonisamide Oral Suspension
• Description :Zonisamide is a sulfonamide anticonvulsant approved for use as an adjunctive therapy in adults with partial-onset seizures. Zonisamide may be a carbonic anhydrase inhibitor although this is not one of the primary mechanisms of action. Zonisamide may act by blocking repetitive firing of voltage-gated sodium channels leading to a reduction of T-type calcium channel currents, or by binding allosterically to GABA receptors. This latter action may inhibit the uptake of the inhibitory neurotransmitter GABA while enhancing the uptake of the excitatory neurotransmitter glutamate.

• Class- Antidementias; Antiepileptic drugs; Antiparkinsonians; Benzoxazoles; Small molecules; Sulfonamides
• Mechanism of Action –Antioxidants; Calcium channel antagonists; Sodium channel antagonists

Zonisamide Moa

• Orphan Drug Status –No
• Indication -For use as adjunctive treatment of partial seizures in adults with epilepsy.
• Protein binding -40% (at concentrations of 1.0-7.0 µg/mL)
• Half-life– 63 hours

An estimated 65 million people have epilepsy globally, and 1 in 26 people will develop epilepsy in the United States. Epilepsy can also present comorbidities and complications such as learning disabilities, autism, anxiety, or depression, contributing to the burden on patients and their families in the management of this complex brain disorder.

“The provider community continues to seek reliable formulations of medicines that may reduce the epilepsy patient and caregiver burden and help improve treatment adherence,” said Dr. Jim Wheless, Chair, Pediatric Neurology, University of Tennessee Health Science Center. “ZONISADE™ addresses an important unmet need in patients who have difficulty swallowing or who are unable or unwilling to take tablets.”
