However, a wide range of actions have been reported to contribute to the drug’s diverse effects, such as: increasing the levels of gamma-aminobutyric acid (GABA) in the brain, inhibiting voltage-gated sodium channels, reducing levels of excitatory amino acid (such as beta-hydrobutryric acid), inhibiting calcium channels, modulating dopaminergic and serotonergic transmission, and inhibiting histone deacetylase.

Common side effects reported include tremors, confusion, fatigue, dizziness, nausea, weight gain, abdominal cramps, and abnormal liver functioning. Other potential side effects include liver damage (i.e., hepatotoxicity), metabolic and endocrine adverse...
