ABSTRACT

OBJECTIVE: To evaluate the experience of prescribing phenosanic acid in the practice of a neurologist/epileptologist when prescribing the second, third anticonvulsant drug (AED) as part of combination therapy for patients with manifestations of fatigue due to epilepsy. MATERIAL AND METHODS: 501 patients with focal epilepsy accompanied by asthenic disorders were included in the observational program. The observation program protocol included 5 visits, including visit 1, at which screening and inclusion in the OP took place. The observation period was 10 months. At baseline and at the end of the 10-month follow-up, the patients' condition was assessed according to the following indicators frequency and transformation of attacks with focal onset, severity of fatigue (self-assessment scale MFI-20); quality of life (questionnaire QoLiE-10-P); frequency of attacks with focal onset. The safety of phenosanic acid (Dibufelon) was also assessed. RESULTS: In 10 months after the inclusion of Dibufelon as the 2nd, 3rd AED in the treatment regimen, a statistically significant (p<0.01) decrease in the frequency of seizures was observed in general - in 88% of patients; by 50% or more - in 76% of patients; transition from the group with a large number of seizures to the group with a smaller number of seizures - 74% of patients. Also when taking phenosanic acid, a positive dynamics of seizure type was noted a reliable decrease in the proportion of patients with seizures with secondary generalization from 70% to 56%; a decrease in the number of focal seizures with impaired consciousness from 65% to 53%. In addition, there was a 38% decrease in the severity of fatigue on the MFI-20 scale (the greatest decrease on the «Mental fatigue¼ scale), improvement in the quality of life - a 2.7-fold increase in the mean values of the QOLIE-10 questionnaire. CONCLUSION: The addition of phenosanic acid to antiepileptic therapy as a second or third AED allows for better control of seizures, leading to a decrease the frequency and severity of attacks and the severity of fatigue both, and an increase of the quality of life of patients with epilepsy.
