Narcolepsy Therapeutics Market Size and Trends
The global narcolepsy therapeutics market reached US$ 2.93 billion in 2023, with a rise to US$ 3.19 billion in 2024, and is expected to reach US$ 6.98 billion by 2033, growing at a CAGR of 9.1% during the forecast period 2025–2033. The narcolepsy therapeutics market is witnessing steady growth, driven by recent FDA approvals, reformulated drugs, and an active pipeline targeting unmet needs. The approval of LUMRYZ, a once-nightly extended-release sodium oxybate, marked a significant advance by reducing the dosing burden compared with older twice-nightly oxybate formulations, improving patient adherence and convenience.
Established wake-promoting agents such as modafinil and armodafinil remain standard first-line treatments for excessive daytime sleepiness, while low-sodium oxybate formulations like Xywav and legacy products such as Xyrem continue to play a central role in managing cataplexy and severe symptoms under restricted distribution programs. Alongside these therapies, next-generation candidates such as orexin-2 receptor agonists (e.g., TAK-861) are showing promise in clinical trials, with the potential to directly address the underlying pathophysiology of narcolepsy and redefine long-term care strategies.
At the same time, advances in digital health and remote monitoring tools are enhancing diagnosis, treatment personalization, and adherence monitoring, reflecting the broader shift toward patient-centric and technology-driven healthcare delivery. Collectively, these developments are accelerating the growth of the narcolepsy therapeutics market while raising new considerations around accessibility, safety monitoring, and reimbursement.

Global Narcolepsy Therapeutics Market: Executive Summary
Market Dynamics
Driver: Rising Prevalence of Sleep Disorders
The rising prevalence of sleep disorders is a key driver of the narcolepsy therapeutics market, as increasing awareness and diagnosis translate into higher demand for effective treatments. According to the American Sleep Apnea Association, an estimated 50–70 million adults in the United States suffer from sleep-related problems, with narcolepsy affecting nearly 1 in 2,000 people, many of whom remain undiagnosed.
The broader increase in conditions such as obstructive sleep apnea, insomnia, and restless legs syndrome has heightened attention on sleep health, encouraging more patients to undergo diagnostic evaluations like polysomnography, which often reveal underlying narcolepsy. For instance, the National Institute of Neurological Disorders and Stroke highlights that narcolepsy is frequently misdiagnosed as depression or epilepsy, but improved screening is now bringing more patients into the therapeutic fold.
The launch of advanced drugs like modafinil, armodafinil, sodium oxybate, and LUMRYZ further supports treatment uptake as patients seek better daytime functioning and nighttime symptom relief. Collectively, the surge in sleep disorder prevalence is expanding the diagnosed narcolepsy population and directly fueling the demand for specialized therapeutics.
Restraint: Side Effects and Safety Concerns
Side effects and safety concerns pose a significant restraint to the growth of the narcolepsy therapeutics market. Many commonly prescribed therapies, including central nervous system stimulants, wake-promoting agents, and sodium oxybate, are associated with adverse effects such as cardiovascular complications, dependency risks, nausea, dizziness, and sleep disturbances.

Global Narcolepsy Therapeutics Market Segment Analysis
The global narcolepsy therapeutics market is segmented by disease type, therapeutic type, and distribution channel, and region.
Product Type: The central nervous system stimulants segment is estimated to have 39.2% of the narcolepsy therapeutics market share.
Central nervous system (CNS) stimulants dominate the narcolepsy therapeutics market because they effectively target excessive daytime sleepiness (EDS), the most debilitating symptom of narcolepsy, making them the preferred first-line treatment.
Medications like modafinil (PROVIGIL), armodafinil (NUVIGIL), and methylphenidate work by promoting wakefulness and improving alertness without significantly disturbing nighttime sleep. Their widespread clinical use, established safety profiles, and ability to enhance daily functioning for patients contribute to their market dominance.
Additionally, these stimulants can be combined with other therapies, such as sodium oxybate for cataplexy management, allowing a flexible, symptom-focused approach that further reinforces their central role in narcolepsy care. Moreover, CNS stimulants are widely supported by clinical guidelines and real-world evidence, which further reinforces physician confidence in prescribing them.
Recent developments in this landscape have further solidified the segment’s position. For instance, in January 2025, Apotex Inc., Canada’s largest pharmaceutical company, announced that its affiliate Nuvo Pharmaceuticals (Ireland) DAC acquired U.S. rights to PROVIGIL (modafinil) and NUVIGIL (armodafinil), adding these branded therapies to Apotex Group’s global portfolio of over 550 prescription, OTC, and biosimilar products.
The central nervous system depressants segment is estimated to have 31.6% of the narcolepsy therapeutics market share.
Central nervous system (CNS) depressants represent the fastest-growing segment in the narcolepsy therapeutics market, primarily driven by the increasing adoption of sodium oxybate and its extended-release formulations for managing cataplexy and excessive daytime sleepiness. These therapies offer a unique mechanism of action compared to stimulants and wake-promoting agents, providing more comprehensive symptom control and improving nighttime sleep quality in patients.
The segment’s growth is further supported by favorable regulatory approvals, expanding insurance coverage, and ongoing clinical developments focused on next-generation oxybate therapies with reduced dosing frequency and improved safety profiles. As awareness of cataplexy management increases and patient preference shifts toward effective, long-term treatment options, CNS depressants are positioned to record the highest growth rate within the therapeutic landscape.
Geographical Analysis
The North America narcolepsy therapeutics market was valued at 42.1% market share in 2024
North America is expected to continue its leadership in the narcolepsy therapeutics market, driven by several key factors. The region boasts a high prevalence of the disorder. For instance, according to the American Heart Association, Inc., an estimated 135,000 to 200,000 people in the United States have narcolepsy, although the actual number may be higher due to frequent underdiagnosis. Narcolepsy often begins in childhood or adolescence, and individuals with a family history of the disorder face a significantly increased risk.
Advancements in diagnostic capabilities, coupled with increased awareness and improved reimbursement policies, have facilitated earlier detection and better management of narcolepsy. Additionally, the robust healthcare infrastructure and significant pharmaceutical investments in North America have fostered a conducive environment for the development and approval of novel therapies.
Recent developments also underscore North America's pivotal role in advancing narcolepsy treatments. In 2024, Avadel Pharmaceuticals received FDA approval for Lumryz, an extended-release sodium oxybate formulation, for the treatment of cataplexy and excessive daytime sleepiness in pediatric patients aged 7 years and older. This once-a-day bedtime treatment offers a more convenient dosing schedule compared to traditional therapies.
Axsome Therapeutics' AXS-12 has demonstrated promising results in Phase 3 trials, showing significant reductions in cataplexy frequency and improvements in excessive daytime sleepiness, cognition, and overall narcolepsy severity. These findings have positioned AXS-12 as a potential new treatment option for narcolepsy.
Furthermore, in June 2024, Harmony Biosciences' Wakix (pitolisant) was approved for pediatric use, expanding treatment options for younger patients with narcolepsy. These advancements reflect a dynamic and evolving landscape in narcolepsy therapeutics within North America.
Overall, North America's strong healthcare infrastructure, high awareness and diagnosis rates, supportive regulatory environment, and active pharmaceutical research and development make it the leading region in the narcolepsy therapeutics market, ensuring continued innovation and improved patient outcomes.
