Market Overview:

Epilepsy is a chronic neurological disorder characterized by recurring seizures and affects more than 50 million people globally, according to WHO. The increased awareness and diagnosis of the disease, particularly in developing countries, coupled with the introduction of new and advanced AEDs with improved efficacy and tolerability, are accelerating market growth.

Epilepsy drugs, or AEDs, aim to stabilize abnormal brain activity and reduce or prevent seizures. The market includes first-generation, second-generation, and third-generation drugs tailored to treat specific seizure types including focal seizures, generalized seizures, and non-epileptic seizures.

Epilepsy Drugs Market Dynamics

Growth Drivers:

✅ Rising Global Prevalence of Epilepsy

• More than 80% of people with epilepsy live in low- and middle-income countries, and the growing elderly population is contributing to increased cases.
• Improved diagnostic methods, awareness campaigns, and early detection are fueling diagnosis rates globally.

✅ Innovations in Drug Development

• Recent years have seen the emergence of second- and third-generation AEDs such as levetiracetam, lacosamide, and perampanel, which offer fewer side effects and higher patient adherence.
• Precision medicine and gene-based therapies are paving the way for personalized treatment approaches.
• In January 2024, Eisai Co., Ltd. received approval in Japan for an injectable formulation of Fycompa (perampanel) for patients unable to take oral medications.

✅ Government Support and Improved Healthcare Infrastructure
