Definitions
- the present invention relates to a pharmaceutical composition for the treatment of convulsive seizures containing perampanel, a pharmacologically acceptable salt thereof or a hydrate thereof, peranpanel, a pharmacologically acceptable salt thereof or water thereof.

- the present invention relates to a method for treating convulsive seizures using GABAergic drugs and peranpanels, pharmacologically acceptable salts thereof or hydrates thereof.
- Convulsive seizures are defined as convulsive seizures that last for a certain length of time or repeat even with short seizures and no recovery of consciousness during that time. In general, the condition persists for more than 30 minutes and does not recover, but in recent years, if it does not converge even after 5 minutes from the onset of convulsions, it has been proposed that treatment should be considered as a seizure intussusception and treatment should begin. (Status epilepticus: pathophysiology and management in adults. Lancet Neurol 2006, 5, 246-56).
- Incidence of convulsive seizures is not limited to people with a history of epilepsy, but can be caused by a variety of causes, including drug addiction, medical illness, acute brain damage (encephalitis, cerebral hemorrhage, cerebral infarction, post-choking encephalopathy, etc.) Can occur.
- antiepileptic drugs are not necessarily expected to be effective in treating convulsive seizures.
- Convulsive seizures are considered to be a neurological emergency. In the treatment of convulsive seizures, it is necessary to achieve rapid seizure cessation in order to prevent death, the persistence of serious sequelae, and the onset of epilepsy. Drug treatment for convulsive seizures is performed by intravenous administration. Currently, according to the European Neurological Society Guidelines (EFNS guideline on the management of status epilepticus in adults.
- benzodiazepines such as lorazepam or diazepam (including combinations with phenytoin) If treatment is started with drugs and seizures are not stopped, rapid seizure control using general anesthetics such as midazolam, propofol, and barbiturate is recommended for brain protection. For partial seizures, if benzodiazepine drugs are ineffective, there is no clear basis for considering the use of injections such as phenobarbital, valproic acid, and levetiracetam to alleviate physical stress due to general anesthesia. Is shown as
- antiepileptic drugs as therapeutic agents for convulsive seizures has been reported at the animal experiment level, but there are actually injectable preparations that can be used for convulsive seizures.
- Available antiepileptic drugs are limited to benzodiazepines such as diazepam and lorazepam, phenytoin, phosphenytoin, phenobarbital, and valproic acid.
- Intravenous preparations of levetiracetam and lacosamide can be used, although indications for convulsive seizures are not approved.

Lithium chloride (LiCl) 3 mEq / kg is intraperitoneally administered 1 day before pilocarpine administration. The next day, scopolamine methyl bromide 5 mg / kg and pilocarpine 30 mg / kg are administered intraperitoneally to induce convulsions. The convulsion expression was defined as the convulsion expression based on the continuous manifestation of spike waves on the electroencephalogram.
- Lithium chloride (LiCl) 3 mEq / kg is intraperitoneally administered 1 day before pilocarpine administration. The next day, scopolamine methyl bromide 5 mg / kg and pilocarpine 30 mg / kg are administered intraperitoneally to induce convulsions.
- Example 2 Evaluation of drug efficacy in the pilocarpine-induced convulsion status model
- the drug was administered once from the tail vein 30 minutes after the onset of convulsions.
- the drugs were mixed and administered (simultaneous administration).
- the effect was judged to be effective when complete disappearance of the convulsion wave was achieved 30 minutes after drug administration, and other effects were judged to be ineffective.
- the results of drug effectiveness are shown in Table 1 with the number of effective cases as the numerator and the number of cases as the denominator.
