Antiepileptic (anticonvulsant) drugs are pharmaceutical substances that reduce the excitability of brain neurons and relieve muscle cramps. Medications for epilepsy do not eliminate the cause of the disease, but control its manifestations, so that a person can lead a full life.

Epilepsy is a chronic noncommunicable disease of the brain that affects people of all ages. Around 50 million people worldwide have epilepsy, making it one of the most common neurological diseases globally. Nearly 80% of people with epilepsy live in low- and middle-income countries.
