Sodium valproate does not usually show effects on the eyes, and can cause gastrointestinal disturbances, confusion, and unfavorable speech, among other adverse effects. Sodium valproate usually reduces neuronal excitability by increasing the synthesis of gamma-aminobutyric acid and decreasing its degradation, thereby elevating the concentration of the inhibitory neurotransmitter gamma-aminobutyric acid. It is useful in the treatment of petit mal seizures and infantile spasms, and can be used in the treatment of epilepsy and mania. Prolonged overdose may cause nausea, stomach pain, diarrhea and other uncomfortable symptoms. When using the drug, you should pay attention to applying the drug under the guidance of a doctor to avoid uncomfortable symptoms, and it is forbidden to use it in patients with allergies, hepatic impairment, blood diseases and other patients.
