    Our technological expertise
    is in Product Performance


Rottendorf eliminates the need for customers to provide expertise on product technology and technical operations, as we fully understand the galenical design of the product and all critical parameters during technology transfer. For Rottendorf, this also means providing the technical expertise that is needed to solve design-based product problems, identifying process improvement potential and corresponding solutions, and successfully providing technical trouble shooting for all product related and manufacturing related issues.

Product Development

Development Phase of the product lifecycle

Rottendorf Pharma designs and develops solid dosage formulations from 2 kg to 150 kg in our state-of-the-art Development Center that is both GMP compliant and FDA approved – something not all CDMOs can offer. Technology for hot melt extrusion, hot melt granulation, and the development and production of pellets is available. Special emphasis is placed on improved availability of poorly soluble APIs.

Customers can choose from individual or complete services, including process and formulation optimization, upscaling, clinical trial manufacturing, analytical method development, stability studies, and regulatory support. Rottendorf’s development expertise is grounded in the knowledge of commercial manufacturing operations and requirements. We formulate with the end in mind – delivering formulations that are ready to be easily and robustly manufactured at a commercial scale.

product transfer

Quality by Product Transfer

Product Transfer involves transferring to the CDMO the manufacturing and packaging processes as well as the analytical methods – whether for established products already on the market or newly approved drugs. It is crucial that the process of transferring products from a pharmaceutical sponsor to the CDMO is carefully planned and well executed. Product transfer is far more than a handoff, rather, it is a two-way transfer of knowledge between contract giver and receiver, for a dialogue to fully evaluate risk and optimize processes so that both the final drug product and the contract experience meet the client’s expectations.

Rottendorf Pharma follows precise procedures and takes ownership of processes to ensure a successful Product Transfer. Throughout the transfer phase, Rottendorf’s approach to Product Transfer as an exchange rather than a handoff means continuous engagement with our clients.

Product Transfer and Quality Ensurance

To ensure quality of a Product Transfer, Rottendorf provides:

  • A designated project leader for the customer throughout the transfer phase
  • Management of all external/internal activities throughout the transfer phase
  • Design of efficient and robust manufacturing processes
  • Detailed risk evaluation
  • Management of the timeline and budget control
  • Responsibility for the customers’ product until validation is successfully finalized

Product Technology  

Our competence is your advantage

With the Product Technology department Rottendorf has created a knowledge hub for all product related matters during the commercial phase of the product lifecycle. The department comprises the departments Technical Product Support, Bulk Manufacturing Process Excellence, Packaging Process Excellence and Packaging Process Design.


Commercial Phase of the product lifecycle

Rottendorf’s Technical Product Support, as a part of the TPO Center, is first point of contact for clients in case technical anomalies (so called “issues”) are detected during the commercial production. In such cases, the TPS project managers take ownership and solve the issue jointly with our client and the specialist departments involved. The solving of those issues and the resulting corrective and preventive actions follow precise standardized processes.


Technical Product Support/Quality Ensurance

To ensure quality, Rottendorf provides:

  • One designated project leader for all technical product related issues
  • Efficient resolution and ownership of product related issues
  • Change Management


For the commercial bulk manufacturing, and for the commercial packaging as well, Rottendorf has established a dedicated team for the continuous optimization of the manufacturing processes. To maintain robust and stable manufacturing processes is essential for keeping our promise to our clients to always deliver on time.
