Carbatrol (CBR) is a new multiple-unit, sustained-release dosage form of carbamazepine (CBZ) developed by Pharmavene. We present a multicenter, outpatient, randomized, double-blind parallel group study (No PI 101) carried out in two centers in Poland. CBR was evaluated in 47 patients with uncontrolled partial onset seizures. During the 28-day baseline period, patients were required to have at least two seizures and to take CBZ at a therapeutic level, a second antiepileptic drug was allowed but not valproic acid (VPA ). Patients were randomized to VPA or to CBR (dosages 800, 1200, 1600 mg/day). Criteria for escape relative to baseline were: two-fold increase in monthly seizure frequency, two-fold increase in 2-day seizure frequency, two-fold increase in weekly seizure frequency, single generalized tonic-clonic seizure (GTCs) if none occurred during baseline or prolongation of GTCs. The primary efficacy variable was the number of patients escaping in each treatment group. Nineteen patients on VPAand 7 on CBR met escape criteria. CBR adverse experiences were all mild or moderate in severity. CBR therapy was effective in the treatment of partial complex seizures with or without generalization.

The incidence of epilepsy is high in the elderly. Increasing awareness of this phenomenon has led to a better understanding of the predominant seizure types, their clinical manifestations, and the most appropriate treatment regimens. Carbamazepine, phenytoin, and valproic acid are considered to be first-line antiepileptic drugs (AEDs). However, the newer AEDs gabapentin, lamotrigine, and tiagabine also warrant consideration as first-line agents because of their efficacy and favorable side-effect profiles. This is particularly important because aging produces physical changes in the patient that can increase the likelihood of adverse effects. To select the appropriate drug and dosage for each individual, a variety of issues must be considered. These include age-related changes in body composition and physiology, as well as the pharmacokinetics, routes of administration, drug interactions, adverse-effect profiles, and cost of available agents.

Chronic administration of antiepileptic drugs without history of unprovoked epileptic seizures are not recommended for epilepsy prophylaxis. Conversely, if the patient suffered the first unprovoked seizure, then the presence of epileptiform discharges on the EEG, focal neurological signs, and the presence of epileptogenic lesion on the MRI are risk factors for a second seizure (such as for the development of epilepsy). Without these risk factors, the chance of a second seizure is about 25-30%, while the presence of these risk factors (for example signs of previous stroke, neurotrauma, or encephalitis on the MRI) can predict >70% seizure recurrence. Thus the International League Against Epilepsy (ILAE) re-defined the term 'epilepsy' which can be diagnosed even after the first seizure, if the risk of seizure recurrence is high. According to this definition, we can start antiepileptic drug therapy after a single unprovoked seizure. There are four antiepileptic drugs which has the highest evidence (level "A") as first-line initial monotherapy for treating newly diagnosed epilepsy. These are: carbamazepine, phenytoin, levetiracetam, and zonisamide (ZNS). The present review focuses on the ZNS. Beacuse ZNS can be administrated once a day, it is an optimal drug for maintaining patient's compliance and for those patients who have a high risk for developing a non-compliance (for example teenagers and young adults). Due to the low interaction potential, ZNS treatment is safe and effective in treating epilepsy of elderly people. ZNS is an ideal drug in epilepsy accompanied by obesity, because ZNS has a weight loss effect, especially in obese patients.

Before therapy, six patients presented abnormalities of SCM responses on the painful side, six patients with bilateral abnormalities, and five patients with normal responses. A significant variation in the responses after therapy was found only in the patients with unilateral abnormalities: these patients and the patients with normal reflexes before therapy also had a good response to the therapy with significant pain relief.

There was a slight predominance of men (55.11%) over women (44,8%). A great majority of the patients did not have family history of epilepsy, and the average age of on set was 20.062 years. Idiopathic epilepsy was predominant with a 48,3%, 26,77% were cryptogenic and 25,19% symptomatic. Of this, the most frequent etiology was sclerosis and atrophy of the temporal lobe, followed by cerebrovascular disease. As to image studies 96,06% had CT, MRI or both; and 94,48% had an EEG. Of all the patients a great majority are receiving treatment with one antiepileptic drug (81,88%). Valproic acid and carbamazepine are the most commonly used. 51,98% of patients have not had a seizure in at least 8 months.
Our results showed a similar efficacy of oxcarbazepine and traditional antiepileptic drugs over time, but the difference in safety and tolerability between the two groups was significant: traditional AEDs caused more side effects, both serious and non serious.

We included 13 studies in this review. Individual participant data were available for 2572 participants out of 3394 eligible individuals from nine out of 13 trials: 78% of the potential data. For remission outcomes, a HR < 1 indicated an advantage for carbamazepine and for first seizure and withdrawal outcomes a HR < 1 indicated an advantage for lamotrigine.The main overall results (pooled HR adjusted for seizure type) were: time to withdrawal of allocated treatment (HR 0.72, 95% CI 0.63 to 0.82), time to first seizure (HR 1.22, 95% CI 1.09 to 1.37) and time to six-month remission (HR 0.84, 95% CI 0.74 to 0.94), showing a significant advantage for lamotrigine compared to carbamazepine for withdrawal but a significant advantage for carbamazepine compared to lamotrigine for first seizure and six-month remission. We found no difference between the drugs for time to 12-month remission (HR 0.91, 95% CI 0.77 to 1.07) or time to 24-month remission (HR 1.00, 95% CI 0.80 to 1.25), however only two trials followed up participants for more than one year so the evidence is limited.The results of this review are applicable mainly to individuals with partial onset seizures; 88% of included individuals experienced seizures of this type at baseline. Up to 50% of the limited number of individuals classified as experiencing generalised onset seizures at baseline may have had their seizure type misclassified, therefore we recommend caution when interpreting the results of this review for individuals with generalised onset seizures.The most commonly reported adverse events for both of the drugs across all of the included trials were dizziness, fatigue, gastrointestinal disturbances, headache and skin problems. The rate of adverse events was similar across the two drugs.The methodological quality of the included trials was generally good, however there is some evidence that the design choice of masked or open-label treatment may have influenced the withdrawal rates of the trials. Hence, we judged the quality of the evidence for the primary outcome of treatment withdrawal to be moderate for individuals with partial onset seizures and low for individuals with generalised onset seizures. For efficacy outcomes (first seizure, remission), we judged the quality of evidence to be high for individuals with partial onset seizures and moderate for individuals with generalised onset seizures.
