Market Segmentation Analysis:
By Product Type
The Montelukast Sodium Amorphous sub‑segment dominated the product‑type category with a 65.0% market share in 2024. Manufacturers favored the amorphous form because it improved solubility and bioavailability and required fewer processing steps, reducing time‑to‑market and lowering production cost. The remaining 35.0% was held by the Montelukast Sodium Crystalline sub‑segment, which retained demand where long‑term stability and batch-to-batch consistency mattered. The amorphous form’s manufacturing efficiency and formulation flexibility remain the primary drivers of its dominance.
- For instance, Teva Pharmaceutical Industries is also recognized among the top companies producing Montelukast Sodium, serving diverse markets with regulatory compliance and manufacturing capabilities to meet global demand.
By Dosage Form
Within the dosage-form segment, the Tablet form commanded a leading 75.0% share in 2024, reflecting strong demand for standard, easy-to-administer dosage forms in both prescription asthma and allergic rhinitis therapies. Chewable Tablets captured 15.0% of the share, driven by pediatric and geriatric patient preferences, while Oral Solutions accounted for the remaining 10.0%, serving niche cases requiring dose flexibility or swallowing avoidance. The Tablet’s dominance stems from established manufacturing infrastructure, lower per-unit costs, and widespread patient acceptance.
- For instance, Montelukast widely prescribed for asthma and allergic rhinitis is available as a film-coated tablet, chewable tablet, and even oral granules, offering flexibility across age groups.
By Application
In the application segment, Asthma emerged as the dominant sub‑segment with a 55.0% share in 2024, owing to the prevalence of chronic asthma worldwide and frequent prescription of montelukast as maintenance therapy. Allergic Rhinitis held 25.0%, buoyed by rising allergy incidence and physicians’ growing preference for leukotriene-modifier therapy. Urticaria represented 10.0%, Bronchospasm 7.0%, and Others combined 3.0%. Demand in Allergic Rhinitis and other respiratory-related conditions contributed significantly to overall volume, but Asthma remained the principal driver of growth.
Key Growth Drivers
Increasing prevalence of chronic respiratory diseases drives demand
The rising global incidence of asthma and allergic rhinitis fuels the expansion of the Montelukast API market. As more patients are diagnosed with chronic respiratory disorders, demand for controller medications like the API for Montelukast increases substantially. The chronic nature of these diseases ensures recurring prescriptions, boosting consistent upstream demand for API. Healthcare providers’ growing reliance on Montelukast for long‑term management of asthma, allergic rhinitis, and related conditions sustains API consumption. Furthermore, increasing awareness and better diagnostic techniques lead to earlier detection, further driving the demand for Montelukast therapies.
- For instance, Merck’s Singulair, one of the leading Montelukast-based therapies, is regularly prescribed in asthma management, contributing to a substantial volume of Montelukast API consumption in global markets.
Growing geriatric and pediatric populations widen the patient base
Demographic shifts toward an increasing elderly population often more susceptible to respiratory diseases expand the target patient pool for Montelukast. Additionally, the growing number of pediatric patients with asthma and allergic rhinitis is driving demand for Montelukast, a treatment that is safe and effective for children. Montelukast’s suitability for pediatric and adolescent use makes it a preferred choice in younger populations too. This dual demographic growth (geriatric + pediatric) significantly enlarges the total treatable population, raising demand for Montelukast API. As the population ages and environmental triggers increase, this trend is expected to continue.
- For instance, Dr. Reddy’s Laboratories produces Montelukast Sodium API with a diverse portfolio exceeding 250 APIs and over 1,980 Drug Master Files (with over 1,638 active DMFs) filed across global markets.
Rising environmental pollution and lifestyle changes exacerbate respiratory conditions
Deteriorating air quality, increasing urbanization, and environmental pollution are significant contributors to the rising prevalence of allergic rhinitis, bronchospasm, and asthma. As environmental triggers such as pollutants and allergens become more widespread, more patients require long-term anti‑inflammatory and leukotriene-receptor antagonist therapy. This trend increases prescription volumes of Montelukast, directly boosting the API market. Additionally, changing lifestyle habits, including diet and sedentary living, contribute to the rising incidence of respiratory disorders, further increasing the demand for effective management solutions like Montelukast.
Key Trends & Opportunities
Expansion of Montelukast into multiple respiratory and allergy‑related indications
While asthma remains the core indication, Montelukast’s role in treating allergic rhinitis, exercise‑induced bronchoconstriction, and other related respiratory or allergic conditions is expanding. This broadened therapeutic scope presents opportunities for higher API demand as manufacturers supply varied formulations and dosage forms to meet diverse patient needs. Montelukast is also increasingly being considered for adjunct therapy in combination with other treatments. As healthcare providers look for cost-effective solutions, this expansion of indications opens up new treatment areas, positioning Montelukast as a versatile drug with a broad therapeutic footprint.
- For instance, Merck’s Montelukast demonstrated sustained symptom improvement in seasonal allergic rhinitis patients over four weeks of treatment, showing significant relief compared to placebo across multiple nasal and eye symptom scores.
Growth in generic Montelukast API suppliers and cost‑competitive manufacturing
With the expiration of original patents and the increasing production of generic drugs globally, API suppliers can now produce Montelukast at significantly lower costs, enabling more affordable pricing for finished drugs. This trend is driving the wider adoption of Montelukast, especially in price-sensitive markets where generic medications have become the preferred choice. Generic drug manufacturers continue to improve their production efficiency, enhancing their ability to meet growing market demands. Lower cost and easier access to Montelukast APIs also contribute to an overall expansion in market volume and help reduce healthcare costs globally.
- For instance, JW Pharmaceutical from South Korea leverages advanced manufacturing technology to maintain steady production outputs without compromising quality, meeting both USFDA and GMP compliance.
Key Challenges
Safety concerns and regulatory scrutiny may restrain market growth
Although Montelukast remains widely used, increasing awareness of potential neuropsychiatric and other side effects has led to caution among clinicians, regulators, and patients. Safety concerns such as mood changes, sleep disturbances, and suicidal thoughts have triggered warnings and monitoring guidelines from health authorities. These concerns may lead to stricter prescribing guidelines or regulatory limitations, which would negatively impact demand for Montelukast API. Despite its widespread use, these safety issues remain a challenge in ensuring its continued growth and acceptance among healthcare professionals.
Competition from alternative therapies and treatment modalities
Alternative asthma and allergy treatments such as inhaled corticosteroids, biologics, or other leukotriene inhibitors may reduce reliance on Montelukast. While Montelukast is a widely accepted treatment, newer biologics such as monoclonal antibodies have emerged as promising therapies, especially for severe asthma. As these newer, potentially more effective or safer therapies gain regulatory approval, the growth of the Montelukast API market may be challenged by shifts in clinical preference and treatment guidelines. Moreover, these alternatives often promise fewer side effects, which can make them more attractive to both patients and healthcare providers.
