Pharmacist's Impact on Medication Adherence and Drug-Related Problems in Patients with Epilepsy

Objectives: Drug-related problems (DRPs) and non-adherence are important barriers to ensuring optimal antiseizure drug treatment. The aim of this study was to improve medication adherence, detect and manage DRPs, and decrease the number of seizures with pharmacist-led education in patients with epilepsy. Materials and Methods: A prospective and interventional study was conducted in collaboration with the Department of Neurology, the rational drug usage unit of a hospital pharmacy in a university hospital. The impact of pharmacist-led education on medication adherence and interventions in the management of DRPs was assessed in patients with epilepsy who were admitted to the outpatient clinic. A total of 39 patients with epilepsy were evaluated in terms of medication adherence, DRPs, and seizure control over a 2-month follow-up period and patient satisfaction with pharmacy services at the end of the study. Results: A total of 59 DRPs were detected, and 71.2% of them were accepted and implemented both by physicians and/or patients. Pharmacist interventions solved 62.7% of DRPs. The number of patients with high-level medication adherence significantly increased from 17 to 28 after pharmacist-led education (p < 0.001). The number of seizures decreased in 19 patients (48.7%) during the 2-month period. Patient satisfaction was high in all patients. Conclusion: It is shown that the contribution of pharmacists in treating patients with epilepsy is beneficial in improving medication adherence, detection and management of DRPs, and decreasing the number of seizures.
