Neuraminidase Inhibitors Drug Market Outlook:
Neuraminidase Inhibitors Drug Market size was over USD 2.9 billion in 2024 and is anticipated to exceed USD 5.1 billion by the end of 2034, witnessing over 6.4% CAGR during the forecast period i.e., between 2025-2034. In 2025, the industry size of neuraminidase inhibitors drug is assessed at USD 3.2 billion.
The global neuraminidase inhibitors drug market is driven by the rising patient population suffering from influenza. The World Health Organization has reported that more than 3.4 to 5.2 million people experience severe cases of seasonal influenza, and nearly 290,010 to 650,005 deaths related to respiratory illness occur every year. Most of the elderly people and children under five are at high risk, and also people suffering from chronic illness. The CDC report has stated that the U.S. has recorded 31.3 million symptomatic flu cases, highlighting a high incidence rate that directly impacts the antiviral drug demand in the year 2023 to 2024. Neuraminidase inhibitors, including zanamivir and oseltamivir, are important for both inpatient and outpatient treatment, mainly during pandemics and flu outbreaks.
On the supply chain side, the active pharmaceutical ingredients for neuraminidase inhibitors are produced in parts of the EU, China, and India, with the final production made in Japan, Europe, and the U.S. As per the U.S. International Trade Commission import/export data, most of the oseltamivir phosphate is imported from China to the U.S. reached USD 63.9 million in 2023, which is 62.3% of the national demand. The producer price index rose to 2.6% for antiviral drugs, while the consumer price index increased to 2.1% for prescription drugs in 2024. Further, the research, development, and deployment have allocated nearly USD 72.5 million in 2024 for antiviral drug discovery and pandemic preparedness projects focusing on improving drug efficacy.

Neuraminidase Inhibitors Drug Market - Growth Drivers and Challenges
Growth Drivers
-
Mapping patient pool and disease prevalence: In Germany, neuraminidase inhibitor-treated influenza infections increased to 3.4 million in 2025, up by 17.3% compared to over past ten years, according to the Robert Koch Institute. At the same time, the CDC documented more than 650,010 influenza-related hospitalizations in the U.S. for the 2023 to 2024 season. These statistics reaffirm a continuously sizable patient pool requiring antiviral treatment throughout North America and Europe. The elderly population and co-morbidities of a chronic nature with diabetes, asthma, and COPD, increase demand for efficacious antivirals such as oseltamivir and zanamivir in inpatient and outpatient facilities as well.
-
Manufacturers' strategies and innovations: Roche, a Tamiflu manufacturer, signed a new licensing agreement in 2024 to produce low-cost generic oseltamivir for public health programs, driving overall volume up by 23.4% globally. On the other hand, Shionogi pushed a new peramivir product with better IV stability and introduced pilot programs in Japan and South Korea. These advancements highlight a move towards broader availability and greater clinical use. These tactics strengthen alliances with ministries of health and expand access to antivirals in underserved areas, in line with pandemic preparedness.
-
Out-of-pocket spending by individuals: The Medicare spending on neuraminidase inhibitors, especially on oseltamivir, reached more than USD 482.6 million, and the out-of-pocket cost by individual payees was USD 74.5 yearly. This impacts robust government backing and affordable access for patients under Part D. These antivirals are a dependable component of public healthcare plans due to their continual formulary inclusion and reimbursement consistency over several years. Sustained funding by the federal demands the stability and revenue streams to the neuraminidase inhibitors drug market for key players dominating in the regulated reimbursement landscape.
Challenges
-
Supply chain and shelf life constraints: Long shelf life antivirals are required by government stockpiling. Most of the neuraminidase inhibitors provide a timeline of 5 to 5.5 years of shelf stability. The CDC’s Strategic National Stockpile report has stated that millions of oseltamivir doses expired and were wasted during the years 2021 to 2023, surging manufacturers to reform and extend the stability. For instance, the HHS required a heat-stable formulation from Tamiflu’s company in 2023, resulting in a delayed contract for six to seven months. Hence, manufacturers were facing various challenges to meet the stability standard risks and losing the long-term contract during pandemic preparedness.

Neuraminidase Inhibitors Drug Market Segmentation:
Route of Administration Segment Analysis
Oral sub-segment dominates the segment and is forecasted to hold the neuraminidase inhibitors drug market share of 53.1% by 2034. Oral dosage forms are used because of the ease of administration, reduced cost of delivery, and highly suitable for outpatient use. As per the NIH's NIAID Influenza Research Program report, oral neuraminidase inhibitors had the largest utilization during pandemic preparedness activities owing to logistical feasibility. Furthermore, oral avenues decrease the burden in the healthcare system by enhancing early intervention in the home or primary care. This pathway is particularly crucial for rural and low-resource areas where intravenous or inhalation avenues are not readily available.
Drug Class Segment Analysis
Oseltamivir is anticipated to hold the neuraminidase inhibitors drug market share of 49.7% by 2034. Oseltamivir is driven by its availability as an oral medication, well-established safety profile, and inclusion in government stockpiles. The U.S. Strategic National Stockpile holds millions of oseltamivir treatment courses. Oseltamivir's efficacy during seasonal and pandemic influenza epidemics, as well as its inclusion in the WHO Model List of Essential Medicines, solidifies its position as the most trusted neuraminidase inhibitor. Its global availability and large-scale generic manufacturing ensure widespread adoption, mainly in middle-income nations.
End user Segment Analysis
The hospitals and clinics lead the segment and are expected to hold the neuraminidase inhibitors drug market share of 44.2% by 2034. The hospitals and clinics are driven by the rising hospitalization rates due to a severe rise in influenza cases, mainly among the elderly population, people with chronic disease, and immunocompromised patients. According to the CDC report, hospitalization cases related to influenza are more than 650,010 in the U.S. during the high flu season, highlighting the key role of inpatient care settings in the administration of antiviral care therapy. Further, hospitals are the key source for managing complications such as pneumonia and secondary infections, necessitating intravenous or antiviral therapies such as peramivir. Moreover, hospitals provide 24/7 access to critical care and diagnostics for neuraminidase inhibitors therapies.
