Inhalable drugs are medical substances that can be administered locally through the respiratory tract via the lung for rapid therapeutic effects. They are particularly effective for treating lung conditions such as asthma, chronic obstructive pulmonary disease and cystic fibrosis. The lung provides huge surface area for drug absorption as compared to oral administration through the gastrointestinal tract. Inhalable drugs bypass hepatic first-pass metabolism for faster delivery of medications directly to the lung tissues and lower systemic levels. Some key advantages include rapid onset of action within minutes, lower dosing, and reduced side effects as compared to oral medications. Popular inhalable drugs include bronchodilators for asthma and chronic obstructive pulmonary disease like albuterol, corticosteroids, dispersible antibiotics, and insulin. With rising lung diseases globally, the inhalable drugs market is expected to grow steadily in the future.
Market Dynamics:
Global inhalable drugs market is driven by the growing prevalence of respiratory diseases such as asthma and COPD worldwide. For instance, on March 16, 2023, according to the World Health Organization (WHO), chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide, and over 300 Mn people suffered from asthma in 2021, while over 3 Mn people die each year from COPD. Increasing pollution levels and changing lifestyles have contributed to the rising caseload of lung illnesses. The market also benefits from the superior therapeutic efficacy of inhalable drugs in treating conditions, affecting the respiratory tract directly. Technological advancements in drug delivery devices such as metered-dose inhalers (MDIs) and dry powder inhalers (DPIs) are expanding opportunities for novel therapies. However, high costs that are associated with development and production of inhalable drugs limit wider market growth. Additional constraints include stringent regulations around clinical trials and product approval for pulmonary drug delivery systems. Nevertheless, ongoing research and development (R&D) into advanced formulations and combination therapies could unlock new avenues over the forecast period.
