Method for the prevention and control of epileptic seizure associated with Lennox-Gastaut syndrome

DETAILED DESCRIPTION What is claimed is: 1.
A method for the prevention and control of seizures associated with Lennox-Gastaut syndrome which comprises administering to a warm-blooded animal in need of such treatment 2-phenyl-1,3-propanediol dicarbamate in a daily dosage of from about 100 milligrams to about 5 grams.




Description:
The present invention relates to pharmaceutical compositions containing 2-phenyl-1,3-propanediol dicarbamate as an active component and to methods for the prevention and control of epileptic seizures by the use of such compositions.
More particularly, the present invention further relates to methods for increasing epileptic seizure threshold and the prevention of epileptic seizure spread through the administration of therapeutic compositions which contain as an active ingredient 2-phenyl-1,3-propanediol dicarbamate commonly known as Felbamate.
Felbamate is a well known pharmaceutical compound having been described in U.

Epilepsy, a disease which has been characterized as a paroxysmal, self-sustaining and self-limited cerebral dysrhythmia, genetic or acquired in origin and physiologic or organic in mechanism is generally divided into four main types based on the type of seizure that occurs in those afflicted with the disease.
Based on clinical and electroencephalographic observations, the four general subdivisions of epilepsy are: 1.
Grand mal 2.
Petit mal 3.
Psychomotor 4.
Autonomic Those afflicted with epilepsy may present with any one of or a mixture of the foregoing forms of the disease.
In theory, it is believed that anti-epileptic drugs act to prevent or control seizures by acting on the seizure focus which may be a collection of pathologically altered neurons or normal cells having restricted vascular supply or an injured area in which the neurons of a nerve net have been destroyed.
Up to the present time, all drugs used in the treatment of epilepsy function as prophylactics against the symptoms of epilepsy, i
