Rapid Uptake of CGRP Receptor Antagonists Across Acute and Preventive Migraine Treatment to Drive Market Growth

The most prominent factor accelerating the global migraine therapeutics market growth is the rapid adoption of CGRP receptor antagonists. These therapies directly target the CGRP pathway involved in migraine and provide patients with migraine-specific treatment options across both acute and preventive settings. Growing physician familiarity, convenient oral administration, expanding regulatory indications, and increasing availability of products such as ubrogepant, atogepant, and rimegepant are supporting their wider use. Furthermore, the ability of certain CGRP receptor antagonists to address different stages of migraine management is increasing their treatment value and expanding the eligible patient population. Continued label expansions and strong commercial uptake of gepants are therefore expected to strengthen their contribution to overall market growth. 

• For instance, in July 2023, Pfizer launched ZAVZPRET (zavegepant) nasal spray in the U.S. for the acute treatment of migraine with or without aura in adults. ZAVZPRET became the first CGRP receptor antagonist available as a nasal spray, providing a non-oral treatment option for patients who may experience nausea, vomiting, or difficulty taking oral medicines during migraine attacks. The launch expanded Pfizer’s migraine portfolio beyond oral CGRP therapies and increased treatment options within the acute migraine segment.

MARKET RESTRAINTS

High Treatment Costs and Restrictive Reimbursement Policies to Limit Adoption of Advanced Migraine Therapies

The high cost of newer migraine therapies, coupled with prior authorization, step-therapy requirements, and increasing net-price pressure, is expected to restrain the growth of the global market. Newer branded CGRP-targeted therapies can carry substantial published prices. Such pricing can increase payer scrutiny and lead insurers to require patients to first use lower-cost or established treatments before approving newer therapies.

• For instance, in June 2025, Pfizer reported a wholesale acquisition cost of USD 1,028.99 for an eight-tablet pack of NURTEC ODT.
• For instance, in September 2023, an article titled ‘Treatment Patterns, Healthcare Resource Utilization, and Direct Costs Among Patients Initiating Concomitant Use of a Calcitonin Gene-Related Peptide Monoclonal Antibody (CGRP mAb) and Novel Acute Medication in the United States’ was published that reported a substantial increase in migraine-related medication costs from baseline USD 3,101.40 to follow-up USD 10,080.43.

MARKET OPPORTUNITIES

Large Diagnosed and Treated Care Gap to Create New Growth Opportunities

The large gap between the number of individuals living with migraine and those receiving timely diagnosis and appropriate treatment is expected to create a significant growth opportunity for the global market. Many patients continue to experience delayed diagnosis, inadequate treatment, or reliance on conventional symptomatic medicines despite the availability of migraine-specific acute and preventive therapies. Increasing disease awareness, improved physician education, greater access to headache specialists, and expansion of digital and telehealth-based care can help bring a larger proportion of these patients into formal treatment pathways. As more previously untreated or undertreated patients receive appropriate diagnosis, the global market demand is expected to increase. Pharmaceutical companies also have an opportunity to expand patient support, awareness, and geographic commercialization initiatives to improve treatment penetration.

• For instance, in August 2024, Organon and Eli Lilly expanded their commercialization agreement for Emgality (galcanezumab) into 11 additional markets, including Canada, South Korea, Mexico, Saudi Arabia, and the UAE, with the companies specifically emphasizing their aim of bringing preventive migraine treatment to more patients globally. Such instances highlight how pharmaceutical companies are seeking to address the large unmet and undertreated migraine population across international markets.

MARKET CHALLENGES

Variable Patient Response and Frequent Treatment Switching Complicate Migraine Management

The high variability in patient response to migraine therapies is expected to remain a major challenge for the global market. Migraine is a heterogeneous neurological disorder, and patients can respond differently to preventive and acute treatments depending on disease severity, migraine frequency, comorbidities, tolerability, and individual treatment history. As a result, patients may need to try several drug classes before identifying an effective and tolerable therapy. Frequent treatment switching can prolong the time required to achieve adequate migraine control, increase treatment discontinuation, and complicate long-term adherence. This trial-and-error approach can also make it difficult for physicians to select the most appropriate therapy and for pharmaceutical companies to achieve consistent treatment persistence across their migraine portfolios.

• For instance, in April 2023, AbbVie reported results from the Phase III ELEVATE study evaluating QULIPTA (atogepant) in patients with episodic migraine who had previously failed two to four classes of oral preventive therapies. Among the 309 study participants, 56% had previously failed two preventive treatment classes, and 44% had failed three or more, with previous treatments discontinued owing to efficacy or tolerability concerns. This substantial history of prior treatment failure illustrates the variability in patient response and the need for repeated treatment switching in migraine management.

The presentations included results from the REPOSE study evaluating real-world safety and efficacy of 155–195U onabotulinumtoxinA, pooled PREEMPT analyses assessing headache-free days, and studies examining BOTOX in combination with CGRP monoclonal antibodies.

The atogepant segment is projected to grow at a 20.85% CAGR during the forecast period.

By Disease Indication

Larger Addressable Patient Population Boosted Dominance of Episodic Migraine Segment

Based on disease indication, the market is segmented into episodic migraine, chronic migraine, and other migraine syndromes.

In 2025, the episodic migraine segment dominated the global market, primarily due to the substantially larger population of patients experiencing migraine below the chronic-migraine frequency threshold. Population-based evidence indicates that most individuals with migraine experience comparatively fewer monthly migraine days, creating a broad patient pool requiring acute therapy and, depending on attack frequency and disability, preventive treatment. As patients with episodic migraine may require repeated acute treatment and some progress toward higher-frequency disease requiring prevention, the large addressable population translates into substantial prescription volumes and supports the segment's dominant contribution.

• For instance, in June 2023, Eli Lilly announced results from the CHALLENGE-MIG study evaluating Emgality against Nurtec ODT for the prevention of episodic migraine in adults. The study enrolled 580 participants and demonstrated continued pharmaceutical investment in dedicated episodic migraine therapies, reflecting the significant commercial and clinical importance of this large patient population.

Based on treatment intent, the market is segmented into acute/abortive treatment, preventive treatment, rescue and emergency treatment, and others.

By treatment intent, the acute/abortive treatment segment held the largest share in 2025. Migraine attacks require rapid symptom relief regardless of whether patients are also receiving preventive therapy. Acute medicines are used across both episodic and chronic migraine populations and include widely prescribed NSAIDs, triptans, gepants, ergot derivatives, and other rescue treatments, creating a broad treatment base. As these medicines are taken when attacks occur, recurring migraine episodes generate repeated treatment utilization, thereby increasing prescription and unit volumes. The introduction of newer migraine-specific acute therapies is further expanding this segment beyond conventional triptans and analgesics.

• For instance, in December 2025, AbbVie announced Phase III ECLIPSE results demonstrating that atogepant achieved superiority over placebo for pain freedom when evaluated for the acute treatment of migraine in adults. The development of an established preventive gepant for acute migraine treatment illustrates the increasing pharmaceutical focus on expanding options within the large acute-treatment setting.

The preventive treatment segment is projected to grow at a CAGR of 10.10% during the forecast period.

By Route of Administration

Convenience and Broad Availability Across Multiple Drug Classes Led to Oral Segmental Dominance

Based on route of administration, the market is segmented into oral, subcutaneous, intramuscular, and others.

The oral segment dominated the global market in 2025 based on route of administration. The segment dominated owing to the convenience, ease of administration, and extensive availability of oral drugs across both acute and preventive migraine treatment. Major migraine drug classes, including triptans, NSAIDs, gepants, anticonvulsants, and several other preventive medicines, are available in oral formulations, allowing this route to address a considerably broader patient population than injectable or intramuscular therapies. The increasing adoption of oral CGRP antagonists has further strengthened the segment by bringing targeted migraine therapy into a convenient non-injectable format.

• For instance, in April 2024, Pfizer announced the commercial availability of NURTEC ODT (rimegepant) in Canada for the acute treatment of migraine in adults. NURTEC is supplied as an orally disintegrating CGRP receptor antagonist tablet, demonstrating continued geographic commercialization of convenient oral targeted migraine treatment.

The subcutaneous segment is projected to grow at a CAGR of 9.14% over the forecast period.

Higher Disease and Treatment Burden Along with Broad Product Approvals Supported Adult Segment Dominance

Based on age group, the market is segmented into pediatric and adults.

The adult segment dominated the global market in 2025 due to the substantial disease burden among working-age populations and the broader availability of approved therapies for adults compared with younger patients. The large number of commercially established products results in greater diagnosis-linked prescription activity, treatment switching, and long-term preventive utilization within adults. Although pediatric therapeutic options are expanding, much of the established commercial migraine treatment landscape continues to be centered on adult patients, thereby supporting the segment's higher market contribution.

• For instance, in April 2023, AbbVie announced U.S. FDA approval of QULIPTA (atogepant) for the preventive treatment of chronic migraine in adults, expanding its previous episodic migraine indication. The approval enabled a single once-daily oral product to address migraine prevention across both episodic and chronic disease frequencies in the adult population, broadening its addressable treatment base.

The pediatric segment is projected to grow at a CAGR of 12.46% over the forecast period.

By Distribution Channel

High Outpatient Prescription Volumes and Easy Medicine Accessibility Led to Retail Pharmacy Segmental Dominance

Based on distribution channel, the market is segmented into hospital pharmacies, drug stores & retail pharmacies, specialty pharmacies, and online pharmacies.

The drug stores & retail pharmacies segment dominated the global market in 2025 due to the predominantly outpatient nature of migraine management and the large volume of prescription and non-prescription medicines dispensed through community pharmacy networks. Retail pharmacies provide convenient geographic accessibility, prescription-refill infrastructure, pharmacist support, and access to both branded and generic treatments, which increases their relevance across a broad migraine patient population. As migraine frequently requires recurring medication rather than continuous hospitalization, repeat prescription fulfillment further increases the transaction volume generated through this channel.

• For instance, in October 2025, Amneal Pharmaceuticals, Inc., announced the U.S. launch of the Brekiya autoinjector, the first and only DHE autoinjector for adults with migraine with or without aura and cluster headache and also a new specialty therapy from Amneal, through prescription exclusively through the Walgreens Specialty Pharmacy and Sterling Specialty Pharmacy.
