(e) Phenobarbital has a wide margin of safety. 4. Resistance to antiepileptic drugs occurs due to: (a) Reduced bioavailability. (b) Ineffective dose. (c) Increased expression of P

A statistically significant increase in elimination half-life in the very elderly (greater than 80 years of age) as compared to younger subjects has been reported, due to a 30% increase in volume of distribution, as well as a 50% reduction in unbound clearance of oxazepam in the very elderly [see PRECAUTIONS, Geriatric Use].

Flumazenil (Romazicon) Patients receiving benzodiazepines chronically are at risk for grand mal seizures with the use of flumazenil. Also, patients with a history of seizures should receive this medication with extreme caution. Seizures have occurred after the reversal of benzodiazepines even with patients not dependent on their use.

After therapeutic doses to children (0.03-0.11 mg/kg) the serum concentrations were in the same range (13-72 ng/ml) as effective concentrations in adults.
