The Russian pharmaceuticals market constitutes the 11th largest in the world and is [1]expected to see high growth going forward. Zonisamide is expected to be available across Russia as adjunctive therapy in the treatment of adult epilepsy patients with partial seizures, with or without secondary generalisation by the end of Eisai's financial year 2012 (30 March 2013).
