In developing countries, from 80 to 90% of the people with active epilepsy do not have access to treatment. A multitude of factors such as nonavailability of antiepileptic drugs (AEDs) contributes to the treatment gap in epilepsy. Our study carried out in 2003 in southern Vietnam showed that 57% of pharmacies had AEDs. A majority of these pharmacies were located in specific areas like market area or hospital area. The pharmacist in charge was present in only 24% of the pharmacies. The different kinds of AEDs available were carbamazepine (94%), phenytoin (61%), valproate (56%) and diazepam (16%). The maximum stock of a drug was two box. The availability of AEDs in southern Vietnam can be regarded as sufficient but does not allow an adequate treatment for a long time. An effort must be made to sensitize professional health workers to decrease the treatment gap in epilepsy.
