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 fatigue» 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.
