Key Players Focusing on Introducing Effective Third Generation Antiepileptic Drugs to Facilitate Market Growth

There is a crucial need for the implementation of new strategies to revisit the standard Antiepileptic Drugs (AED) discovery and development. This will help in achieving the unmet epilepsy treatment needs. Patent expiration of second-generation drugs is the key opportunity for the manufacturers in the development of generic as well as innovative antiepilepsy drugs. Coupled with this, procurement of Food and Drug Administration (USFDA) approval is proving healthy for the market growth and ultimately boosting the industry players to invest in complex clinical trials. For example, in November 2019, the USFDA approved XCOPRI of SK Life Science Inc., indicated for the treatment of partial-onset seizures. Also, In March 2018, Zogenix Inc. announced the positive results of phase-3 clinical trial of its Antiepileptic Drugs AED (FINTEPLA) under development. This continuous research and development to meet the unmet needs is projected to further propel the anticonvulsants drugs market growth during the forecast period.


Green Signal from USFDA to Stimulate Market Value

Despite the availability of AEDs in the market, one-third of the population faces intolerability for drugs. Countless efforts are in line by the manufacturers to diminish this problem. R&D has now been focused on the development of target-specific drugs concerning the neurobiology of the disease condition. Growing prevalence of epilepsy demanding for therapeutically effective medications is creating a pressure among the market players to introduce AEDs. The key decision of USFDA is providing confidence among the players for improving R&D and is also benefiting the patient population. Recently, in January 2020, the USFDA approved Valtoco, a nasal spray for the treatment of epilepsy in patients aged 6 years and older. Also, In June 2018, the USFDA approved Epidiolex for the treatment of rare forms of epilepsy in patients. This is the first drug comprising of active ingredient derived from marijuana. Such decisions taken by the approval committee is helping the manufacturers in providing potential therapies for the epileptic patients.

Active Government Support and Investments to Expedite Market Growth

Epilepsy is among the most common neurological conditions, with significantly higher prevalence in the emerging countries. According to the Epilepsy Foundation of America and the World Health Organization (WHO), in the year 2019 an estimated 50 million people globally had epilepsy. China, India, and Brazil were among the countries with higher proportion of the population suffering from the condition. 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, the Australian government in March 2018 announced an investment worth USD 2 million for conducting medical research on epilepsy.

Additionally, the Morrison Government in April 2019 invested USD 9.2 million for childhood epilepsy medications. The backing of the government is proving beneficial for the patients in controlling the seizures. This is projected to fuel the adoption of anticonvulsants drugs and boost the antiepilepsy drugs market growth. 


Epilepsy Medicine Shortage to Restrict the Market Growth

Despite increasing incidence of epilepsy, seizures, and other chronic conditions in the emerging countries, certain factors are limiting the antiepileptic drugs market growth. One of the major factors restraining the growth of the market is steep rise in medicine supply shortage. Patients are stockpiling these medicines as there is a shortage of drugs in the pharmacies. This has raised an alarm in investigating the medicine supply chain globally. This devastating situation can be seen worsening in the U.K. and in the other European countries such as Britain due to Brexit uncertainty. This is ultimately affecting the global market as the U.K. is becoming a less desirable market for epilepsy medications.

Second Generation Drugs Dominated the Global Market

Based on drug generation, the market for antiepileptic drugs (AED) is segmented into first generation, second generation, and third generation. According to our research findings and estimations, the second-generation drugs segment holds the dominating Antiepileptic Drugs (AED) market share. Second generation drugs include Lyrica, Keppra, Banzel, and others. Lyrica has been the blockbuster drug for epilepsy treatment and has the maximum share in the market. It has proved its potential in slowing the impulses of the brain and controlling the seizures. Pfizer’s Lyrica has dominated the epilepsy market until 2019 before its patent expiry. But it is still in demand owing to the benefits of the drug. Other second-generation drugs have proved their potential in reducing the symptoms of epilepsy.

Third generation drugs such as Vimpat, Briviact, and others are also penetrating the market in full swing and are proving beneficial in curing epilepsy. UCB’s Vimpat is expeditiously increasing in the U.S., Europe, and Japan epilepsy markets. This segment is anticipated to emerge as the fastest growing segment in the market owing to introduction of new drugs and growing investments in R&D of the drugs. For example, UCB received USFDA approval for Briviact to treat partial-onset seizures in pediatric epilepsy patients. Additionally, patent expiration of the second-generation drugs  are providing opportunities for the manufacturers in launching new medications. First generation drugs are likely to witness a slower growth in the market owing to the decrease in sales of the medications.

By Distribution Channel Analysis

Increase in Epilepsy to Boost Sales of Hospital Pharmacies

The emergence of hospital pharmacies for neurology, cardiology, and other conditions in developed and emerging countries is attracting a large patient pool suffering from chronic and acute conditions. The pool mainly comprises of patients suffering from conditions which are treated in hospitals equipped with advanced infrastructure and adequate facilities. The hospital pharmacies segment is estimated to have dominant share in the market. Growing number of hospitals, along with adequate reimbursement policies provided by these settings, are some of the major factors responsible for higher proportion of epilepsy patients being treated in these facilities. This is eventually responsible for the adoption of antiepileptic drugs by the hospital pharmacies globally.
