Differences in knowledge about epilepsy and antiepileptic drugs among pharmacy-dispensing workers in Cambodia and in Lao PDR

International audienceEpilepsy is the most common neurological disorder encountered in primary care in Southeast Asia. People with epilepsy require long-term therapy management. Nonadherence to antiepileptic drugs (AEDs) has been identified as a major factor in suboptimal control of epilepsy. Pharmacies offer patients a first-line point of contact with the healthcare system. Many pharmacies operate with limited or nonqualified human resources that can lead to insufficient knowledge, inappropriate supply of medicines, and insufficient counseling.Objective: The aim of this study was to evaluate the qualification and knowledge concerning epilepsy and AEDs among pharmacy-dispensing workers who sell drugs to people with epilepsy.Method: A cross-sectional qualitative study was conducted in public and private pharmacies, in both urban and rural areas of Cambodia and Lao People's Democratic Republic (Lao PDR). The knowledge was collected through a questionnaire.Results: A total of 180 respondents from 123 outlets in the two countries were included in this study. A proportion of 40.8% (31) of respondents in Cambodia and 38.5% (40) in Lao PDR were pharmacists, followed by sellers who did not received any healthcare training with a proportion of 18.4% (14) in Cambodia compared to 20.2% (21) in Lao PDR. Head trauma was cited as the main cause of epilepsy by 72.4% (55) in Cambodia and 27.2% (28) in Lao PDR (p < 0.001). Epilepsy was considered as a contagious disease by 6.6% (5) of respondents in Cambodia compared to 18.4% (19) in Lao PDR (p = 0.03). Eighty-seven percent (66) of respondents in Cambodia knew at least one long-term AED versus 67.3% (70) in Lao PDR (p = 0.003). Phenobarbital was mentioned in more than 90.0% of cases in both countries. In overall, 15.4% (21) thought that if seizures are controlled for some months, people with epilepsy could stop taking their AEDs. Only one respondent from Lao PDR was aware of drug-drug interaction between AEDs and oral contraception.Conclusion: An educational intervention should be implemented to improve the knowledge of epilepsy and AEDs for pharmacy-dispensing workers. This could include advice for all pharmacy-dispensing workers in order to improve AED management and follow-up of therapeutic adherence
