Storage method
This The product should be stored in a sealed container at room temperature.
Synthesis method
By 2-ethyl-2-Methyl succinic acid is obtained by cyclization with ammonia water . Add ammonia (20% ) Join2-ethyl-2-Methyl succinic acid, topHfor10Above. Heat to200-220℃, response20min. Cold to50℃The following, add chloroform. Filter, wash the filter cake with chloroform, discard the combined wash and filtrate, and separate the chloroform layer. Recover chloroform and distill under reduced pressure to collect 150 -160℃（2.13kPa) fraction, Get ethosuximide.
Purpose
Yes A newer class of anti-epileptic drugs used primarily for minor seizures. It has less toxicity and good effect. It is the first choice drug for minor attacks and is widely used. Ethosuximide can aggravate major seizures, so for patients with mixed major seizures, this product cannot be used alone and must be combined with benmabital or phenytoin.
