Freeze & Go Solutions

Are you particular about the "freezing method" of pharmaceutical raw materials? It is possible to freeze and thaw raw materials more safely and securely while maintaining quality!

Of the biopharmaceutical active ingredients, 59.4% are transported in a frozen state. Therefore, the development of controllable and efficient freezing and thawing technologies is increasingly in demand. For example, in the development of COVID-19 vaccines, there has been a growing emphasis on storage and transportation methods, highlighting the necessity for these solutions. Recently, the combination of Allegro BioContainers and RoSS Technology has resulted in the development of an excellent active ingredient management solution through synergistic effects. It allows for the control of frozen active ingredients between the purification process and the formulation and filling processes, enabling stable and safe storage and transportation. Additionally, it prevents losses of active ingredients due to the breakage of frozen single-use packs, bringing the risk of loss close to 0%.

[Column] Management Strategies for Starting Materials in Active Pharmaceutical Ingredients

The selection of starting materials significantly impacts the manufacturing cost of active pharmaceutical ingredients. We would like to introduce our management strategy for starting materials in active pharmaceutical ingredient production.

The selection of starting materials (hereinafter referred to as starting materials) for applications is proposed by pharmaceutical companies in accordance with the general principles of ICH guideline Q11, but it is often the case that they receive frequent inquiries from authorities before approval. At SpiraPharma, when selecting starting materials, organic chemists and analytical chemists collaborate to propose which compounds are suitable as starting materials based on the manufacturing process. Additionally, when establishing management strategies for starting materials, we can obtain data to support responses to authorities through investigations of the behavior of key related substances. For our customers who are challenging the creation of new pharmaceuticals, we will continue to leverage our cultivated technology and experience while furthering our expertise. *For more detailed information on the column, please refer to the related link. For further inquiries, please feel free to contact us.
