The global market for leukotriene inhibitors continues to grow as more chronic respiratory diseases, allergic reactions, and exercise-induced bronchoconstriction cases increase. Market segmentation of Asthma Relievers is based on Drug Type (Montelukast, Zafirlukast, Zileuton ER, Zileuton), Form (Tablets, Chewable Tablets, Oral Granules).
Montelukast Leads Market Demand
Montelukast is the leading leukotriene receptor antagonist (LTRA) prescribed for asthma and allergic rhinitis, and as such dominates the segment to biggest market share. Montelukast is the most widely used leukotriene receptor antagonist and a popular medication for asthma because it can be dosed once daily, has clinical efficacy for airway inflammation and in preventing exercise-induced bronchospasm.
As global demand for non-steroidal treatment of asthma and long-term management for allergic diseases continues to rise, montelukast retains its spot as the drug of choice for pulmonologists and allergists.
The Zafirlukast portion also continues to see steady demand, especially in patients requiring longer-lasting anti-inflammatory effects to manage chronic asthma. Whereas montelukast is typically dosed once daily, zafirlukast is dosed twice daily; however, in patients with severe and persistent asthma, zafirlukast has additional benefits over montelukast. With ongoing studies into individualized treatment plans for asthma, zafirlukast remains relevant in sourcing treatment options in certain patient stratifications.
Tablet Segment Dominates Market Growth
The tablet segment is expected to dominate the leukotriene modifiers market due to preference of most adult patients given the wide availability of convenient, once-daily oral medications. The most commonly prescribed respiratory therapies, due to their ease of administration, accurate dosing, and long-term adherence, are in the form of tablets.
Despite the growing burden of chronic respiratory diseases globally and an increasing awareness of non-steroidal asthma therapies, the demand is still high for leukotriene-modifying tablets. The chewable tablets segment is also growing, particularly among pediatric patients and people who have difficulty swallowing pills.
Montelukast is available as a chewable tablet dosage form and is frequently prescribed for children with asthma and seasonal allergies, in order to provide children with a pleasant-tasting, and once-daily, treatment option. As awareness rises with infrastructure development, high adherence to these medications also led to further opportunities for chewable leukotriene modifiers to expand in availability and prescription rates.
The leukotriene modifiers market is being propelled by the rising demand for effective treatments for asthma, allergic rhinitis and chronic obstructive pulmonary disease (COPD). Increased use of AI in drug development, rising awareness of respiratory diseases and greater adoption of combination therapies drive growth.
Industry leaders are concentrating on next-gen leukotriene receptor antagonists (LTRAs), machine learning-driven drug formulation, and precision medicine solutions to address treatment efficacy, safety, and patient compliance.
