Keppra (Levetiracetam)

Description

Anticonvulsant drugs are traditionally used to treat epilepsy. It is assumed long-term therapy, which can be regarded as a compromise between clinical efficacy, toxicity and cost of treatment. Modern anti-epileptic drugs (AEDs) can achieve remission in 65% of cases, reduce the frequency of attacks - 85%.

New AEDs, which is effective in reducing seizure of different genesis is levetiracetam (Keppra), which is still not widely used in neurological practice, though differs from the first generation of AEDs better tolerability and safety of long-term use.

What is Keppra?

Keppra refers to anticonvulsant drugs, manufactured in the form of capsules, syrup, tablets in a special coating.

Keppra - a structural analogue of piracetam, which in its properties is close to optimal pharmacokinetics for AEDs. It is distinguished by high bioavailability after oral administration (90%), the peak concentration is achieved within 1-3 hours. There is not known effect on other drugs, including AEDs in combination therapies. The half-life of the drug - about 8 hours (in the central nervous system - more), making it possible to double the reception. Doses of Keppra may vary from 500 to 5000mg/day (30-40mg/kg/day).

Clinical studies of Keppra

There are several studies on the positive impact of Keppra on cognitive function in patients with epilepsy. Thus, in one of them were evaluated the speed of speech and attention in patients with partial epilepsy therapy before Keppra (as adjunctive therapy) and 7 weeks after its application. Also, other patients in control group, receiving other anti-epileptic drugs, examined on neuropsychological testing with the same time interval. The results showed significant improvements in attention and speed of speech in the study group, compared with the control group.
