Antiepileptic Drugs (AED) Market Growth Factors

Increase in Product Approvals for Epileptic Disorders to Drive Market Growth

Despite the availability of AEDs in the market, one-third of the population faces drug intolerability. The manufacturers are making countless efforts to diminish this problem. R&D personnel have now focused on developing target-specific drugs concerning the neurobiology of the disease condition. The growing prevalence of epilepsy demanding therapeutically effective medications creates pressure among the market players to introduce AEDs. The critical decision of the U.S. FDA is to provide confidence among the players for improving R&D and benefiting the patient population.

• In June 2023, SK Biopharmaceuticals’ partner Paladin Labs received Health Canada’s  regulatory approval to market and distribute XCOPRI (cenobamate tablets). The tablets would be used for adjunctive therapy in the management of partial-onset seizures in adults with epilepsy who are not satisfactorily controlled with conventional treatment.

Such decisions taken by the approval committees help the manufacturers in providing potential therapies for epileptic patients.

Active Government Support and Investments to Expedite Market Growth

Epilepsy is the most common neurological condition, significantly more prevalent in emerging countries. Developing countries such as India, China, and Brazil have a higher proportion of the population suffering from the state. In order to minimize the burden of this disease, as well as to expedite the availability of better treatment options, governments from countries across the world are providing active support.

• For example, according to an article published by the Australian Institute of Health and Welfare in 2022, the expenditure for epilepsy accounted for around USD 333.0 million or 0.2% of USD 134.0 billion of recurrent health system expenditure in 2018–19. Also, epilepsy was ranked the 30th cause for disease burden in Australia (2018).

The government's backing is beneficial for patients in controlling their seizures. Such support from the government helps patients manage their seizures. It is understood that the government's support will drive the market for AED drugs. This is estimated to fuel the adoption of AED drugs and boost the growth of the drugs market.

RESTRAINING FACTORS

Lack of Antiepileptic Drugs Supply Restrains the Market Growth

Despite the increasing incidence of epilepsy, seizures, and other chronic conditions in emerging countries, certain factors limit the global antiepileptic drug (AED) market growth. The steep rise in medicine supply shortage is a major factor restraining the market's development. Patients are stockpiling these medicines as there is a shortage of drugs in the pharmacies. This has raised the alarm in investigating the medicine supply chain globally. This devastating situation can worsen in the U.K. and other European countries, such as Britain, due to Brexit uncertainty. This ultimately affects the global market as the U.K. is becoming less desirable for epilepsy medications.

• According to an article published by SWI swissinfo.ch in 2023, Switzerland faced a shortage of certain medicines and plans to boost drug stocks. Christoph Amstutz, head of the Federal Office for National Economic Supply, has said that antiepileptic drugs and medication for Parkinson's disease should be included in the mandatory reserves. Such scenarios of stockpiling have been restricting the Antiepileptic Drugs market growth.

Furthermore, the limited adoption rate for treatment limits the market expansion in many countries. For instance, according to an article published in Epilepsy Action Australia 2023, a recent study commissioned by LivaNova Australia found that despite the widespread awareness of epilepsy, many Australians have a limited understanding of the condition and its treatments. Such factors could restrict the market expansion over the forecast period.
