健康有害性	SYMPTOMS: Symptoms of exposure to this compound via ingestion may include sleepiness, mental confusion, unsteadiness, coma, slow and shallow respiration flaccid muscles, hypotension, cyanosis, hypothermia or hyperthermia, absent reflexes, painful gums and excessive fatigue. Other symptoms of exposure through ingestion may include ataxia, vertigo, nausea, anorexia, vomiting, hyperirritability, emotional disturbances, sexual impotency, diplopia, nystagmus, morbilliform skin eruptions and possible megaloblastic anemia. Ingestion may also lead to sedation, dizziness, an acute feeling of intoxication, maculopapular rash, leukopenia, thrombocytopenia, systemic lupus erythematosus, lymphadenopathy, acute psychotic reactions, hemorrhagic disease in the neonate and osteomalacia. It can cause mental dullness, drooping of the eyelids and, rarely, blurred and narrow vision. It can also cause a coma, the duration of which is dependent on the dose. If the coma continues, moist rales are heard in the lower lung fields, indicating pulmonary edema. Atelectasis or aspiration pneumonia with signs of lung consolidation and fever can also occur. Carbon dioxide retention under these conditions causes acidosis. Death occurs most often from pneumonia, pulmonary edema or refractory hypotension. Cerebral edema contributes to the persistence of coma. Chronic symptoms of ingestion include skin rash, mental confusion, drowsiness, hangover, emotional lability or depression, irritability, poor judgment, neglect of personal appearance and other behavior disturbances. Other symptoms may include general malaise, polyuria, thyroid enlargement, epidermal necrolysis, tremors, central nervous system depression, disequilibrium, personality changes, thirst and impaired sexual function.

用途

薬理研究用。

説明

Primidone is chemically and structurally similar to phenobarbital with the exception that the carbonyl group on C2 is replaced by a methylene group. This modification leads to the production of a drug with strong anticonvulsant properties without expressed soporific effects.

使用

Primidone is mainly used for major attacks.

一般的な説明

Odorless white crystalline powder. Slightly bitter taste. No acidic properties.
