Study of Effects of Levetiracetam Monotherapy on Various Hematological Parameters in Adult Patients Suffering of Epilepsy

Epilepsy is a chronic neurologic disease that is considered the most common neurological diseases in the world and comes third after cerebrovascular and Alzheimer's disease. Epilepsy is a disorder characterized by a long-term tendency to cause epileptic seizures due to abnormal electrical activity in the brain with neurological, cognitive, psychological and social consequences . However, it is not a single disease entity but it is a collection of different kinds of seizures resulting from several mechanisms and different cause. The aim of epilepsy management is complete seizures cessation and maintenance of a good quality of life, which is affected not only by the epileptic attacks but also by the adverse effect of the drugs used .Levetiracetam (LEV) is a relatively new, broad-spectrum AED that has seen extensive use during recent years . Its mechanism of action is not completely known, but differs from those of other AEDs. LEV is described as being well tolerated, and the most common adverse effects are generally mild . Studies evaluating the effect of levetiracetam on hematological parameters have reported a spectrum of hematological abnormalities that ranges from mild thrombocytopenia or neutropenia to anemia, red cell aplasia, until bone marrow failure. Fortunately, potentially fatal hematological disorders such as aplastic anemia are very rare.
