- BackgroundImproved quality of life (QoL) is one of the most important objectives in the treatment of epilepsy. Recent prospective, clinical studies proved no significant differences between brand antiepileptic drugs (AEDs) and their generic equivalents in terms of seizure control, pharmacokinetics, or safety. In this study, we focused on possible changes in QoL and adverse events in connection with generic substitution of levetiracetam (LEV).MethodsThis was a prospective, naturalistic, two-cohort, twin-center study. After a baseline period of 10 weeks, outpatients with epilepsy on stable treatment with Keppra® either continued on this brand (reference group, n = 16) or switched to generic LEV (1A Pharma®) (study group, n = 16) for an eight-week study period. The Quality of Life in Epilepsy Inventory-31 (QOLIE-31) and an adverse events' questionnaire were administered at inclusion, after baseline, and at the end of the study period. The study protocol included a close clinical follow-up with repeated LEV serum concentration measurements and nurse-led outpatient visits.ResultsClinically relevant improvements in overall QOLIE-31 scores according to minimally important change (MIC) estimates were seen in both groups. QOLIE-31 subscales in both groups showed significantly less worry about seizures at the end of the study compared to scores at inclusion (study group: p = 0.01; reference group: p = 0.02). No significant deterioration in QoL or adverse events were observed following generic substitution. No switchbacks occurred.ConclusionsWe found reduced seizure worries over time among people with epilepsy allocated to either generic switch or continued treatment with brand LEV. We hypothesize that the nurse-led structured follow-up had an impact on seizure worries and switchback rates because of reduced nocebo effects. Further studies on generic AED substitution, focusing on psychological outcome measures, are warranted to test this supposition.

- Introduction: About 70 million people worldwide are estimated to suffer from epilepsy. Despite a large variety of old and new antiepileptic drugs on the market, about 30% of people with epilepsy do not become seizure-free with medical treatment. This is a major individual and public health burden. Most of these difficult-to-treat patients are having focal seizures. Zonisamide is effective against focal seizures in adults and children and, thus, a therapeutic option for such patients. Its safety profile needs special attention. Areas covered: Herein, the authors discuss the pharmacology, clinical efficacy and the adverse effects of zonisamide. The article is derived from clinical trial data, long-term studies, meta-analyses, review articles, text books, webpages, and official license information. Expert opinion: Zonisamide has proven to be efficacious in focal epilepsy in children and adults, although it is not more effective than carbamazepine or other antiepileptic drugs. It is also effective in generalized epilepsy and in several other conditions of the CNS. Its safety profile may prevent it from becoming a first-line drug for focal epilepsy or any other indication.

- The prevalence of neurologic and psychiatric diseases has been increasing for decades and, given the moderate therapeutic efficacy and safety profile of existing pharmacological treatments, there is an urgent need for new therapeutic approaches. Nutrition has recently been recognized as an important factor for the prevention and treatment of neuropsychiatric disorders. The omega-3 polyunsaturated fatty acids (n-3 PUFAs) eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) play critical roles in neuronal cell function and neurotransmission as well as inflammatory and immune reactions that are involved in neuropsychiatric disease states. A large number of experimental and epidemiological studies provide a strong basis for interventional clinical trials that assessed the clinical efficacy of n-3 PUFAs in various neurological and psychiatric disorders. Most of these trials found beneficial effects of dietary supplementation with EPA and DHA, and no serious safety concerns have emerged. This review gives an introduction to recent findings on the clinical efficacy of n-3 PUFAs in various neuropsychiatric disorders and the underlying biochemical mechanisms. In addition, the reader will be enabled to identify common methodological weaknesses of clinical studies on n-3 PUFAs, and suggestions for the design of future studies are given.
