The global antiepileptic drugs (AED) market is witnessing steady growth due to the rising prevalence of epilepsy worldwide, increasing awareness regarding neurological disorders, and continuous advancements in drug development. According to Fortune Business Insights, the market was valued at USD 17.82 billion in 2025 and is projected to grow from USD 18.57 billion in 2026 to USD 27.57 billion by 2034, registering a CAGR of 5.10% during the forecast period (2026-2034).
North America dominated the global AED market in 2025, accounting for a 48.40% market share, supported by higher diagnosis rates, strong reimbursement policies, and frequent regulatory approvals for novel epilepsy drugs.
Market Drivers
Epilepsy is one of the most prevalent neurological disorders globally, characterized by recurrent seizures, loss of consciousness, and behavioral disturbances. According to the World Health Organization (WHO, 2023), approximately 50 million people worldwide are affected by epilepsy, with nearly 80% residing in low- and middle-income countries (LMICs). This high disease burden creates a substantial demand for effective and long-term antiepileptic therapies.
The growing prevalence of epilepsy places a significant economic burden on healthcare systems, driving governments and pharmaceutical companies to expand access to treatment. In response, market players are focusing on developing target-specific drugs with improved efficacy and reduced side effects, which is positively influencing market growth.
Impact of COVID-19
The COVID-19 pandemic negatively impacted the AED market, primarily due to reduced patient visits to neurological clinics, disruptions in drug supply chains, and limited access to healthcare services. However, from 2022 onwards, neurological consultations gradually increased, restoring prescription volumes. As a result, the market is expected to regain its pre-pandemic growth trajectory during 2026-2034.
Market Trends
Rising Focus on Third-Generation Antiepileptic Drugs
A key trend shaping the market is the growing emphasis on third-generation antiepileptic drugs, designed to address unmet clinical needs such as drug resistance and adverse effects. Patent expirations of second-generation drugs have created opportunities for pharmaceutical companies to develop both innovative therapies and generics.
For instance, Eisai Co., Ltd. has actively expanded its epilepsy portfolio by launching new formulations of Fycompa (perampanel), including an injection formulation approved in January 2024 in Japan, enhancing treatment options for patients unable to take oral medications.
Market Growth Factors
Increasing Product Approvals
Despite the availability of numerous AEDs, nearly one-third of patients experience drug resistance or intolerability, prompting manufacturers to intensify R&D activities. Regulatory bodies such as the U.S. FDA and Health Canada have been approving new therapies, encouraging innovation.
For example, in June 2023, XCOPRI (cenobamate tablets) received regulatory approval in Canada for adjunctive treatment of partial-onset seizures, supporting market expansion.
Government Support
Government investments and awareness initiatives are accelerating market growth. Public healthcare expenditure on epilepsy management, as seen in countries like Australia, India, and China, is improving patient access to medications and driving adoption of AEDs globally.
Restraining Factors
Drug Supply Shortages
One of the major challenges restraining market growth is the shortage of antiepileptic drugs, particularly in Europe. Brexit-related uncertainties in the U.K. and mandatory drug reserve discussions in Switzerland have disrupted supply chains. Medicine stockpiling and limited availability can negatively affect treatment continuity, thereby restraining market expansion.

Competitive Landscape
The market is highly consolidated, with key players including Pfizer Inc., UCB S.A., GSK plc., Eisai Co., Ltd., and Sanofi. While Pfizer's Lyrica has historically dominated the market, patent expiry has intensified competition from generics and newer therapies.
Conclusion
The global antiepileptic drugs (AED) market is set for steady growth through 2034, supported by rising epilepsy prevalence, continuous drug innovation, and favorable regulatory frameworks. With the market expected to reach USD 27.57 billion by 2034, sustained R&D investments, government support, and improved access to treatment will be critical in addressing unmet patient needs and driving long-term market expansion.
