Abstract |
Five newborn infants ( birth weight 2900--3600 g) were given diazepam ( Valium, LaRoche) for convulsive disorders in 4 equal doses intravenously, intramuscularly, rectally and orally with at least 24 hours intervals. Three infants were given doses of 1 mg diazepam/kg body weight, and 2 0.5 mg/kg. The parenteral solution of the drug was given intravenously, intramuscularly and rectally. Powder of tablets was given orally. After intravenous administration very high peak values of plasma- diazepam concentration were obtained (5775--10800 ng/ml after 1 mg/kg, 2750 and 6450 ng/ml after 0.5 mg/kg). Next to intravenous administration rectal administration caused the most rapid increase in plasma- diazepam concentration. Presumed anticonsulsive concentrations (150--300 ng/ml) were obtained within 5 min with 1 mg/kg as well as 0.5 mg/kg rectally. Rectal administration therefore could be a suitable treatment for seizures in the newborn infant. Accumulation of the main depressive metabolite N- desmethyldiazepam occurred in all infants. This phenomenon must be taken into account when repeated doses of diazepam are administered.
