    Use of phenobarbitone for treating childhood epilepsy in resource-poor countries
    (South African Medical Journal, 2005) Wilmshurst, Jo M; Van Toorn, Ronald
    Should the continued use of phenobarbitone for childhood epilepsy in resource-poor countries be considered a form of discrimination? Phenobarbitone was recommended by the World Health Organization (WHO) as the first-line agent for the control of seizures,1 but this has been contested on the grounds that it is biased against resource-poor countries.2 It was first used as an anticonvulsant in 1912, but now has little role to play in First-World countries where the newer generation agents are readily accessible. Phenobarbitone monotherapy has equivalent efficacy to the newer anticonvulsants (phenytoin, sodium valproate and carbamazepine) in children with partial-onset and generalised tonic-clonic seizures.3 Phenobarbitone is cheap, readily available, and easy to use and store. However, it has definite cognitive and behavioural side-effects in many children. It can exacerbate seizures in about 35% of children, and extreme caution should be taken with children who have a pre-morbid state of behavioural problems or attention deficit hyperactivity disorder (ADHD).

    Withdrawal of parenteral phenobarbitone - implications for resource-poor countries
    (2005) Wilmshurst, J M; Van Toorn, Ronald; Newton, C R J C
    Parenteral phenobarbitone is an integral part of the management of status epilepticus, especially in the context of resource-poor countries. It is highly effective at controlling seizures. It is safe, cheap, can be given by rapid intravenous push or intramuscular route, boluses can be repeated, and it is recommended as part of the Advanced Paediatric Life Support guidelines. The proposed alternatives lack efficacy, practicality and/or place the child in status epilepticus at risk of respiratory compromise. The impact of the loss of parenteral phenobarbitone would be increased cardiac complications, lack of early seizure control, prolonged seizures resulting in brain damage and systemic complications. Increased numbers of patients will require artificial ventilation in centres without facilities, and centres with facilities will be unable to cope with the load of ventilated patients because of lack of safe transport systems and bed space.
