Market Overview
The global inhaled insulin market was estimated at USD 609 million in 2024 and is anticipated to grow to around USD 2,597 million by 2034, registering a CAGR of 15.6% from 2025 to 2034. Inhaled insulin serves as a needle-free, rapid-acting substitute for traditional subcutaneous injections, primarily addressing mealtime glucose management in individuals with type 1 and type 2 diabetes. Its quick absorption rate, ease of administration, and improved patient adherence make it particularly appealing to those with needle aversion or those requiring flexible home and outpatient insulin management.
