ABSTRACT
INTRODUCTION: The efficacy and tolerability of lamotrigine (LTG) in monotherapy and in combination therapy have been demonstrated in clinical trials. The aim of the ERELMO study was to retrospectively evaluate the effectiveness and safety of LTG, as monotherapy in the control of epileptic seizures in routine clinical practice in Spain. PATIENTS AND METHODS: 446 clinical records were selected of patients with LTG treatment in the twelve months previously to the beginning of the study. The main endpoints retrospectively analyzed were effectiveness (percentage of patients with 50% or greater reduction in seizure frequency, improvement in seizure control, percentage of patients remaining-seizure free at 2, 6 and 12 months of LTG monotherapy), and safety (adverse event profile reported and treatment withdrawal). RESULTS: The mean age was 41 years old, 57.8% were women. LTG monotherapy treatment (mean maintenance dose was 217.2 mg/day) reduced mean seizure frequency as compared with the basal condition at different study time points (2, 6, 12 months; p < 0.0001). At the end of the study 77% of the patients were seizure free. Loss of treatment effectiveness was shown in 8.5% of patients. Adverse reactions were reported by 15% of patients, the most frequent being insomnia, somnolence, headache and rash. At the end of the study, 88.8% patients were still receiving LTG monotherapy. CONCLUSIONS: The present study supports the use of LTG monotherapy due to its effectiveness and good tolerability to promote treatment compliance in usual clinical conditions in patients with epilepsy.

AIMS: In this study we review the economic impact involved in suffering from this disease in an attempt to determine how it affects both the individual and society, and the potential benefits deriving from its prevention and treatment. DEVELOPMENT: The World Health Organisation and the World Bank have pointed out that 90% of the costs generated by epilepsy are produced in developing countries. Yet in most developed countries the economic impact of the disease remains partially hidden for patients by the existence of publicly funded health service. As regards spending on pharmaceutical products in Spain, the subgroup made up of the antiepileptic drugs accounted for 1.36% of the total spending throughout the year 2001. Nevertheless, the main economic consequence for most patients is the limitation they suffer in their occupational activities, which is inversely proportional to the degree of control over their seizures and considerably higher than in the general population. Moreover, in epilepsy we must not forget the costs linked to its numerous psychological and social consequences. CONCLUSIONS: As happens in other areas of health care, the way epilepsy is attended depends to a large extent on economic factors. Further studies are therefore needed to provide us with a better understanding of the role played by economics in the field of health care.
