About E Keppra®

Developed by UCB S.A. of Belgium in the early 1980s, E Keppra® is a centrally acting anti-epileptic therapy with a mechanism of action that differs from that of any conventional anti-epileptic drug. Marketed outside of Japan under the brand name Keppra®, the product has accumulated six million patient years of use worldwide. In Japan, it has been used as adjunctive therapy with other anti-epileptic drugs for partial-onset seizures in adult patients since September 2010 through a co-development/co-commercialization alliance between Otsuka Pharmaceutical and UCB Japan. As a result of this co-development, further indications for monotherapy for partial-onset seizures, adjunctive therapy with other anti-epileptic drugs for generalized tonic-clonic seizures, and children aged 4 years and older were added. Additional formulations, including dry syrup and I.V. infusions, have also become available.

Formulations currently available in Japan are:
 E Keppra® Tablets 250mg
 E Keppra® Tablets 500mg
 E Keppra® Dry syrup 50%
 E Keppra® for I.V. infusion 500mg
