The rising demand for respiratory disease treatments is closely linked with the growing reliance on outsourced inhalation development, driven by both clinical complexity and economic realities. Respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, and respiratory infections are becoming more prevalent due to urbanization, air pollution, smoking habits, occupational exposure, and aging populations. These diseases often require targeted drug delivery directly to the lungs, making inhalation the preferred route for faster onset of action and reduced systemic side effects.
Developing inhalation therapies is technically demanding. It involves specialized formulation expertise, device compatibility testing, aerodynamic particle size optimization, and strict regulatory compliance. Many pharmaceutical and biotechnology companies lack in-house capabilities for these highly specific processes. Outsourcing inhalation development to contract development and manufacturing organizations (CDMOs) has become an attractive strategy. Outsourced partners provide advanced infrastructure, experienced scientific teams, and established regulatory know-how, enabling sponsors to reduce development timelines and control costs.
High technical complexity and regulatory hurdles remain significant challenges in inhalation drug development and related outsourcing services. Inhalation therapies are fundamentally different from conventional oral or injectable products because the drug must be delivered as an aerosol with precise control over particle size, airflow behavior, and lung deposition. Even minor changes in formulation, excipients, or manufacturing conditions can affect aerosol performance, dose uniformity, and therapeutic outcomes. This level of sensitivity requires advanced formulation techniques, specialized testing methods, and close integration between the drug and its delivery device, thereby increasing development complexity.
Regulatory expectations add another layer of complexity. Inhalation products are regulated as combination therapies, meaning both the drug and the device must meet rigorous safety, quality, and performance standards. Developers are required to generate extensive in vitro, preclinical, and clinical data to demonstrate consistency, reproducibility, and patient safety. Regulatory agencies also demand detailed characterization of aerosol properties and robust comparability studies, particularly for generic or reformulated products.
The expansion of generic and value-added inhalation products is becoming a key growth driver within the respiratory therapeutics landscape. As patents on several widely used inhalers expire, pharmaceutical companies are actively pursuing generic alternatives to address cost pressures in healthcare systems and improve patient access to essential respiratory treatments. Unlike conventional generics, inhalation products are technically complex, requiring precise replication of aerosol performance, dose delivery, and device functionality. This complexity has created a strong demand for specialized development capabilities.
Beyond standard generics, companies are increasingly focusing on value-added inhalation products that offer clinical or user-experience improvements. These may include enhanced delivery devices, improved dose consistency, reduced dosing frequency, or combination therapies that simplify treatment regimens. Such innovations allow manufacturers to differentiate their products while leveraging established active ingredients, thereby reducing development risk relative to entirely new drugs. Regulatory authorities often require comprehensive comparability and performance data for both generic and value-added inhalers, making development resource-intensive.
The small-molecule segment is expected to lead the market, accounting for approximately 55% of the market in 2026, owing to its well-established role in respiratory therapy and demonstrated suitability for inhalation delivery. These molecules are easier to formulate into stable aerosols, offer predictable lung deposition, and demonstrate reliable pharmacokinetic profiles. Their relatively lower manufacturing costs and scalable production further support widespread adoption.
Many frontline respiratory treatments for asthma and COPD rely on small molecules that are well-known and widely used by physicians. One such treatment is Serevent (salmeterol), developed and marketed by GlaxoSmithKline (GSK). Salmeterol is a long-acting β2-adrenergic agonist, commonly used in inhalers, that helps manage asthma and chronic obstructive pulmonary disease (COPD) by relaxing airway smooth muscle, thereby facilitating airflow.
The large-molecule segment is projected to be the fastest-growing product category in respiratory therapy, as innovation extends beyond traditional bronchodilators. Biologics, peptides, and protein-based therapies are being explored to treat severe asthma, rare pulmonary disorders, and inflammatory pathways that small molecules cannot effectively address. Advances in formulation science and inhalation devices now enable the delivery of these delicate molecules to the lungs with greater stability and accuracy.
One example is Pulmozyme® (dornase alfa), a biologic inhaled therapy developed by Genentech/Roche. Pulmozyme is a recombinant human DNase I protein used in the treatment of cystic fibrosis to reduce mucus viscosity in the lungs, improving airway clearance and lung function. Unlike conventional small-molecule bronchodilators, this protein-based large molecule targets the physical properties of mucus, providing therapeutic benefits that small molecules cannot achieve for certain lung conditions.
The large segment is expected to dominate the market, accounting for nearly 60% of revenue in 2026, owing to its strong differentiation and limited competition. Development complexity, advanced manufacturing requirements, and specialized delivery systems create high entry barriers, allowing innovators to maintain stronger pricing power and longer product lifecycles. Many large-molecule therapies are positioned as specialty or breakthrough treatments, often supported by robust clinical evidence and targeted patient populations.
Tyvaso DPI contains treprostinil, a prostacyclin analogue delivered via dry-powder inhaler for the treatment of pulmonary arterial hypertension (PAH) and pulmonary hypertension associated with interstitial lung disease (PH-ILD). In 2024, Tyvaso generated about US$1.62 billion in revenue, showing strong commercial performance for a biologic/large-molecule inhaled therapy and illustrating how advanced inhaled biologics can command high sales in specialized respiratory markets.
The medium company size segment is likely to be the fastest-growing, owing to its balance of agility and capability. Unlike large players, they can adapt quickly to new technologies, customer needs, and regulatory changes, while still possessing sufficient resources to invest in specialized infrastructure and skilled talent.
