Phenobarbital prophylaxis of post traumatic epilepsy.

Phenobarbital (PB) was tested for its efficacy in averting post-traumatic epilepsy (PTE) in patients with non-missile head injuries. The protocol envisaged the administration of PB throughout a period of two years in randomly assigned doses ranging from 0.5 to 1.5 and from 1.6 to 2.5 mg/kg/day. The study included neurologic examination, EEG and plasma PB levels. Ninety patients, 83 of whom with serious head injury followed the prescribed treatment for the entire period. Two adult patients manifested seizures 5 and 10 months after the trauma. They were being treated with doses over 1.5 mg/kg/day. Another patient had a seizure six months after the end of the prophylaxis. Low doses of PB and monitoring permitted a reduction of side effects. The low incidence of PTE indicates that PB has an efficient prophylactic effect. The results also show that a low dosage has a favourable effect.
