99% Purity Pharmaceutical Raw Materials API Levetiracetam
Levetiracetam is used in combination with other medications to
treat certain types of seizures in people with epilepsy.
Levetiracetam is in a class of medications called anticonvulsants.
It works by decreasing abnormal excitement in the brain.
Levetiracetam has been approved in the United States as add-on
treatment for partial (focal), myoclonic, and tonic-clonic
Levetiracetam has been approved in the European Union as a
monotherapy treatment for epilepsy in the case of partial seizures,
or as an adjunctive therapy for partial, myoclonic, and
tonic-clonic seizures.Levetiracetam has been shown to reduce
partial (focal) seizures by 50% or more as an add-on medication.
It is also used in veterinary medicine for similar purposes.
Levetiracetam is sometimes used off-label to treat status
epilepticus or to prevent seizures associated withsubarachnoid
Levetiracetam has potential benefits for other psychiatric and
neurologic conditions such as Tourette syndrome, anxiety disorder,
and Alzheimer's disease. However, its most serious adverse effects
are behavioral, and its benefit-risk ratio in these conditions is
not well understood.
Levetiracetam has not been found to be useful for treatment of
neuropathic pain, nor for treatment of essential
tremors.Levetiracetam has not been found to be useful for treating
autism, but is an effective treatment for partial, myoclonic, or
tonic-clonic seizures associated with autism spectrum disorder.
Levetiracetam is a Pregnancy Category C Drug. Studies in female
pregnant rats have shown minor fetal skeletal abnormalities when
given maximum recommended human doses of levetiracetam orally
throughout pregnancy and lactation.
Studies were conducted to look for increased adverse effects in the
elderly population as compared to younger patients. One such study
published in Epilepsy Research showed no significant increase in
incidence of adverse symptoms experienced by young or elderly
patients with central nervous system (CNS) disorders.
Levetiracetam may be used in children depending on age and type of
seizure. Animal studies in juvenile rats and dogs did not
demonstrate a potential for age-specific toxicity.
Kidney impairment decreases the rate of elimination of
levetiracetam from the body. Individuals with reduced kidney
function may require dose adjustments. Kidney function can be
estimated from the rate of creatinine clearance.
Dose adjustment of levetiracetam is not necessary in liver
