Vetina’s Levetiracetam
Description:
- Levetiracetam is a drug within the Pyrolidine class that is used to treat various types of seizures stemming from epileptic disorders.
- Levetiracetam is a broad-spectrum anti-epileptic agent, which is routinely used as adjunct treatment, or as monotherapy
- It is an anticonvulsant that works by decreasing abnormal activity in the brain helps to manage epilepsy in companion animals.
- Levetiracetam may be useful as a antiseizure medication in dogs that are not well controlled with phenobarbital and bromides or when either bromides or phenobarbital are not tolerated.
- Some evidence suggests that in dogs suffering from phenobarbital liver toxicity, the addition of levetiracetam will allow reduction of their phenobarbital dosage without increasing seizure frequency.
Indications:
- Focal epilepsy
- Partial-complex epilepsy
- Generalized epilepsy
- Prevention of seizures
Composition:
Each film coated tablet contains:
- Levetiracetam IP…………500 mg
- Excipients…………….…..q.s.
CLINICAL PHARMACOLOGY:
- Levetiracetam appears to prevent seizure activity via the selective inhibition of hypersynchronized epileptiform burst firing without affecting normal neuronal transmission.
- Levetiracetam has also been shown to indirectly affect GABAergic neurotransmission (despite having no direct effect on GABAergic or glutamatergic receptors) and modulate ionic currents.
CONTRAINDICATIONS:
- Levetiracetam is contraindicated in animals who have previously exhibited hypersensitivity to it or any of its components. It should be used with caution in animals with renal impairment; dosage amounts or dosing frequency changes should be considered.
ADVERSE REACTIONS:
- Levetiracetam appears to be very well tolerated in the limited number of dogs treated. Changes in behavior and gastrointestinal effects could occur.
- In cats, the drug appears to have a wide safety margin, but less clinical use has occurred in that species. Transient in – appetance has been reported in some cats receiving the drug.
