Antiepileptic Drugs and the Relationship with the Intestinal Microbiota

This review of the literature examines the use of antiepileptic medications and how they relate to gut microbiota. Relationships exist between the makeup of the intestinal microbiota and the development and execution of the most fundamental physiological processes. Additionally, it affects the functioning of the central nervous system (CNS) by interacting with the microbiota-intestine-brain axis. The use of pharmaceutical medication is one of the factors that can alter the composition of the gut microbiota. When treating epilepsy, various drug types are used, each with a different mechanism of action. Among the medications in question are to piramate, primidone, phenytoin, carbamazepine, and phenobarbital. The similarity in structure and function between enteric and nerve cells establishes the connection between the brain and the gut. Valproic acid significantly reduced intestinal inflammation in research involving rats with colitis. Its limited ability to treat seizures in these circumstances may be due to the enterocytes limited ability to absorb this medicine. The study came to the conclusion that colitis patients and people with healthy gut, brain, and microbiota interactions typically respond better to antiepileptics and anticonvulsants than people with imbalances in this axis. These imbalances can result in a lower seizure threshold and an increased frequency of epileptic seizures.
