Novasep API Manufacturing Services Banner

Small molecule API manufacturing is a complex challenge requiring chemistry expertise as well as specialized facilities, regulatory experience & supply chain management.

That’s why pharmaceutical innovators are today relying more and more on CDMOs (Contract Development and Manufacturing Organizations) for the manufacturing of their API (Active Pharmaceutical Ingredient). Indeed, working with CDMOs allows drug companies to benefit from a long-term partnership with an experienced team offering specific skills, equipment, capabilities, and technical resources that are not available internally, resulting in a robust and secure supply chain, reducing risks and optimizing costs.

But selecting the best supplier for an API manufacturing project is not always straightforward.
Here are some of the key considerations when choosing a CDMO partner:
