Terapijske indikacije:

Zonisamide capsules are indicated as adjunctive therapy in the treatment of partial seizures in adults with epilepsy. Zonisamide capsules are contraindicated in patients who have demonstrated hypersensitivity to sulfonamides or zonisamide. The abuse and dependence potential of zonisamide has not been evaluated in human studies (see WARNINGS, Cognitive/Neuropsychiatric Adverse Events subsection). In a series of animal studies, zonisamide did not demonstrate abuse liability and dependence potential. Monkeys did not self-administer zonisamide in a standard reinforcing paradigm. Rats exposed to zonisamide did not exhibit signs of physical dependence of the CNS-depressant type. Rats did not generalize the effects of diazepam to zonisamide in a standard discrimination paradigm after training, suggesting that zonisamide does not have abuse potential of the benzodiazepine-CNS depressant type.

ZONISAMIDE CAPSULES USP, for oral administration
Rx Only
DESCRIPTION
Zonisamide, USP is an antiseizure drug chemically classified as a
sulfonamide and
unrelated to other antiseizure agents. The active ingredient is
zonisamide USP, 1,2-
benzisoxazole-3-methanesulfonamide. The empirical formula is C H N O S
with a
molecular weight of 212.23. Zonisamide USP is a white powder, pKa =
10.2, and is
moderately soluble in water (0.80 mg/mL) and 0.1 N HCl (0.50 mg/mL).
The chemical structure is:
Zonisamide is supplied for oral administration as capsules containing
100 mg
zonisamide.
Each 100 mg capsule contains the labeled amount of zonisamide plus the
following
inactive ingredients: microcrystalline cellulose, hydrogenated
vegetable oil, gelatin and
colorants. Components of gelatin capsules (For 100 mg: titanium
dioxide, gelatin and
FDA/E172 red iron oxide). Imprint ink dye (Black SW- 9008/SW-9009).
CLINICAL PHARMACOLOGY
MECHANISM OF ACTION: The precise mechanism(s) by which zonisamide
exerts its
antiseizure effect is unknown. Zonisamide demonstrated anticonvulsant
activity in
several experimental models. In animals, zonisamide was effective
against tonic
extension seizures induced by maximal electroshock but ineffective
against clonic
seizures induced by subcutaneous pentylenetetrazol. Zonisamide raised
the threshold
for generalized seizures in the kindled rat model and reduced the
duration of cortical
focal seizures induced by electrical stimulation of the visual cortex
in cats. Furthermore,
zonisamide suppressed both interictal spikes and the secondarily
generalized seizures
produced by cortical application of tungstic acid gel in rats or by
cortical freezing in cats.
The relevance of these models to human epilepsy is unknown.
Zonisamide may produce these effects through action at sodium and
calcium channels.
In vitro pharmacological studies suggest that zonisamide blocks sodium
channels and
reduces voltage-dependent, transient inward currents (T-type Ca
