Semaglutide spray is a novel delivery method of GLP-1 receptor agonist, aiming to provide a more convenient needle-free option for patients requiring weight management or treatment of type 2 diabetes. It delivers the traditional subcutaneous injection of semaglutide drug molecules through oral or nasal mucosal spray, utilizing specific absorption-promoting technology to allow it to enter the bloodstream. This design is expected to significantly improve medication compliance and experience, especially for those who are fearful or inconvenient about injections. Currently, this formulation is mostly in the clinical research stage. Its core challenge lies in ensuring that the drug can stably and efficiently penetrate the mucosal barrier to achieve the same bioavailability and stable blood drug concentration as the injection formulation. If successfully launched, it will represent an important technological leap in the treatment of metabolic diseases, but its actual efficacy and safety still need to be ultimately verified by strict clinical trial data.

Semaglutide COA
Semaglutide spray was initially developed for the treatment of type 2 diabetes. In recent years, it has gained significant attention due to its remarkable weight loss effect. Its spray-dried powder for inhalation (Spray Dried Powder for Inhalation, Sema-DPI) is a new administration method designed to overcome the limitations of traditional injection and oral formulations, enhancing the stability and safety of the drug.
Stability
Optimization of structure and enhancement of stability
Semaglutide has significantly enhanced its stability through molecular structure optimization. Specifically, the research team replaced alanine at the 8th position of semaglutide with α-amino isobutyric acid (Aib), which strengthened its resistance to dipeptidyl peptidase-4 (DPP-4), thereby reducing the degradation of the drug in the body. Additionally, a C18 fatty acid side chain was attached at the 26th position, and a glutamic acid was used as the linker, increasing the drug's affinity for albumin and preventing rapid clearance by the kidneys, further extending the drug's half-life. These structural optimizations enable Semaglutide to exert its effects stably in the body for a long period of time.
The influence of spray drying process on stability
The spray drying technology is employed to prepare the Semaglutide inhalation powder aerosol to enhance its stability and inhalability. During the spray drying process, by optimizing process parameters (such as feed rate, inlet temperature, nozzle diameter, etc.), powder particles with good aerodynamic properties can be obtained. Studies have shown that the Sema-DPI prepared using spray freeze-drying (SFD) technology has a rougher particle surface, providing better aerodynamic performance, thereby enhancing the stability of the drug and the efficiency of lung deposition. Moreover, the spray drying process can also maintain the activity of the drug, ensuring its stability during storage and use.
Storage Conditions and Stability
The stability of Semaglutide is also affected by storage conditions. Traditional injection and oral formulations usually require refrigeration for storage to maintain the drug's activity. However, the spray-dried powder aerosol, through optimizing the formulation and process, may reduce the reliance on refrigeration conditions and improve the stability of the drug during storage. This is undoubtedly an important advantage for patients requiring long-term treatment.
Safety
Safety assessment in clinical trials
The safety of Semaglutide has been thoroughly evaluated in multiple clinical trials. In the SUSTAIN series of studies, compared with other control groups (including placebo and other hypoglycemic drugs), the incidence of overall adverse events and severe adverse events of Semaglutide was similar. The most common adverse events were gastrointestinal reactions, such as nausea, vomiting, and diarrhea, but these symptoms were usually mild to moderate and transient. As time went on, most patients gradually adapted to the drug and the gastrointestinal discomfort would also alleviate.
Safety study of inhalation preparations
For the Semaglutide inhalation powder, researchers also conducted rigorous safety assessments. In animal experiments, continuous inhalation of a high dose (4.1 mg/kg/day) of Semaglutide DPI for 28 days did not result in significant pulmonary or systemic lesions. This indicates that Semaglutide DPI has good safety in animals. Additionally, the spray drying process, by optimizing particle characteristics, reduces the irritation of the drug to the respiratory tract, further enhancing the safety of the inhalation formulation.
Safety considerations for special groups
Although Semaglutide has shown good safety in clinical trials, its use in special populations (such as pregnant women, lactating women, children, and adolescents) still requires caution. Currently, there is insufficient evidence to demonstrate the safety of Semaglutide in these populations, so it should be avoided. For the elderly, especially those with impaired liver and kidney function, when using Semaglutide, attention should be paid to dose adjustment and close monitoring of adverse reactions.
The subtle changes in supply chain and cold chain
Semaglutide spray, as a GLP-1 receptor agonist, has achieved remarkable results in the treatment of type 2 diabetes and obesity. Its market demand has soared with the expansion of its indications. However, this growth not only led to the reshaping of the supply chain but also profoundly influenced the operation mode of cold chain logistics, presenting a subtle and complex change between the two.

Supply Chain: From Monopoly to Diversified Competition
The supply chain structure of Semaglutide has undergone a transformation from a monopoly to diversified competition. Initially, due to high technical barriers and complex production processes, the number of suppliers for Semaglutide was limited, and the market structure was relatively stable. However, as demand soared, more and more manufacturers entered this field, especially Chinese manufacturers, who quickly gained a dominant position in the global market by virtue of large-scale production and cost advantages.
This change has had a profound impact on the supply chain. On one hand, the increase in the number of suppliers has intensified market competition, leading to price reductions and cost optimization. For instance, the average market price of Semaglutide has dropped by 60% to 70% in just five years, thanks to the decline in the prices of key starting materials, improvements in the process, and adjustments in downstream procurement strategies. On the other hand, the regional dominance of the supply chain has also shifted. China has gradually become the core of the global Semaglutide supply chain, while Europe and the United States have taken on more roles of strategic investment and high-standard production capacity.
Cold Chain: From a Single Demand to a Complex Network
Semaglutide, as a peptide-based drug, has sensitive chemical properties and strict requirements for storage and transportation conditions. Unopened, Semaglutide needs to be refrigerated at a temperature range of 2°C to 8°C to avoid freezing and direct sunlight exposure; after opening, it also requires strict cold chain management to ensure the stability and effectiveness of the drug. This demand makes cold chain logistics an indispensable part of the Semaglutide supply chain.
However, with the changes in the supply chain structure, cold chain logistics is also facing new challenges and opportunities. On one hand, the increase in the number of suppliers and the intensification of market competition have made the demand for cold chain logistics more diverse. Different suppliers may adopt different packaging and transportation methods, which puts higher requirements on cold chain logistics. On the other hand, the rise of Chinese manufacturers in the global market has also promoted the global layout of the cold chain logistics network. To meet the demands of the global market, cold chain logistics enterprises need to establish a more complete and efficient global network to ensure the quality and safety of Semaglutide at all stages.
Subtle Changes: Synergy and Competition between Supply Chain and Cold Chain
During the evolution of the supply chain and cold chain of Semaglutide, there exists a subtle relationship of synergy and competition between the two. On one hand, changes in the supply chain have driven the development of the cold chain. As the number of suppliers increases and competition intensifies, cold chain enterprises need to continuously improve their service quality and efficiency to meet the demands of the supply chain. For instance, by adopting advanced refrigeration technologies, optimizing transportation routes, and strengthening temperature monitoring, cold chain enterprises can ensure the quality and safety of Semaglutide during transportation.
On the other hand, the development of cold chain logistics has also exerted an opposing force on the supply chain. The cost and efficiency of cold chain logistics directly affect the final price and market competitiveness of Semaglutide. Therefore, every link in the supply chain needs to closely monitor the dynamic changes of cold chain logistics and promptly adjust its strategies and layouts. For instance, suppliers can reduce the cost and risks of cold chain logistics by establishing long-term partnerships with logistics companies and jointly developing new packaging and transportation methods.
