Phenytoin intoxication during concurrent diazepam therapy.
Phenytoin elimination is a saturable process obeying Michaelis-Menten kinetics. Plasma phenytoin levels are not related linearly to dose, and small changes in enzyme activity produced by concurrent drug therapy could alter plasma levels. Two cases of phenytoin intoxication associated with simultaneous administration of diazepam are reported. Intravenous phenytoin infusions were given and the ap...
متن کاملElevated plasma free drug concentrations of propranolol and diazepam during cardiac catheterization.
Patients who undergo cardiac catheterization are frequently taking propranolol and are often premedicated with diazepam. Because the intensity of a drug's action is determined by free, or non-protein-bound, levels in plasma, changes in the degree of protein binding may profoundly alter the pharmacologic effect. We examined the effects of heparin on the free levels of propranolol and diazepam in...
متن کاملEffects of the rectal administration of diazepam. Diazepam concentrations in children undergoing general anaesthesia.
Diazepam 1 mg/kg body weight was administered rectally to 14 children (11-22.5 kg) before minor surgery under general anaesthesia. Administration in solution (n = 7) resulted in a rapid increase in serum concentrations which were maintained for 8 h. Administration by suppository (n = 7) resulted in significantly lower serum concentrations at 10 and 20 min, but higher concentrations at 2 h. At o...
متن کاملLong-term response to high-dose diazepam treatment in continuous spikes and waves during sleep.
BACKGROUND This study evaluated whether the reduction in epileptiform activity after treatment with high-dose diazepam in continuous spikes and waves during sleep persists over time. PATIENTS Patients aged 1 to 21 years with continuous spikes and waves during sleep who received high-dose nocturnal diazepam and who had electroencephalogram follow-up were included. Twenty-nine patients met the ...
متن کاملDiazepam and midazolam for sedation during bronchoscopy.
Sir,—It is regretted that the interesting paper by Korttila and Tarkkanen (1985) does not state which preparation of diazepam they used. The early relative potency studies of midazolam and diazepam were undertaken with the organic solvent preparation, Valium. A review (Dundee et al., 1984) of these puts the relative potency of the two drugs at about 1.5:2.1:1. However, if Korttila and Tarkkanen...
