A clinical trial of single dose rectal and oral administration of diazepam for the prevention of serial seizures in adult epileptic patients.
The clinical anticonvulsant efficacy of single dose rectal and oral administration of diazepam 20 mg was examined in two double-blind placebo-controlled trials in adult epileptic patients. All subjects suffered from drug resistant epilepsy and frequently experienced serial seizures. Diazepam was administered rectally as a new experimental suppository formulation immediately after a seizure and was highly effective in preventing recurrent fits within a 24 h observation period (p less than 0.001). Pharmacokinetic studies revealed a wide range of serum diazepam concentrations 60 min after administration of the suppository (mean serum diazepam level 190 +/- 73 (SD ng/ml). In a similar study oral administration of diazepam 20 mg significantly reduced the incidence of serial seizures compared with a placebo (p less than 0.01) and the mean 60 min serum diazepam level was 273 +/- 190 (SD) ng/ml.
