Continuous manufacturing of pharmaceuticals


Continuous manufacturing of pharmaceuticals is changing oral solid dosage (OSD) production. Higher flexibility, shorter development times with minimum API usage, and a direct transfer from development to production without scale-up are among the primary requirements of pharmaceutical manufacturers. In pharmaceutical manufacturing, the processes occur one after the other without interruption while the product is charged and discharged simultaneously. The main challenge with traditional solutions is the precise dosing of the starting materials in a constant mass flow rate of milligrams per second.


Syntegon is tackling the challenges in continuous manufacturing pharmaceuticals with a different approach, called Xelum.


Key benefits

Low API dosage, high accuracy
You can precisely dose APIs of less than 1% while ensuring high content uniformity for your final product.
Your shortcut to production
Thanks to a direct transfer from R&D to production, you don’t require scale-up.
We care for quality
The Xelum platform supports you with easy and reliable quality control as well as integrated traceability.

Your gateway to continuous manufacturing

Shorter time-to-market of new formulations? No scale-up? Full flexibility in batch sizes and processes? Cost reduction? Xelum checks all boxes! No wonder that bluechip companies on three different continents have signed strategic partnerships for the Xelum continuous manufacturing system with Syntegon. Learn more in our video.

OSD: Many facets – one partner

Oral solid dose (OSD) manufacturing is a demanding endeavor. There is no better partner to tackle those tasks with than Syntegon. Our OSD services and process technology will make your production a rock-solid success. Find out more in this video.

Xelum: The fastest way to continuous manufacturing


The Xelum platform doses active ingredients and excipients as discrete masses and not as a continuous mass flow. This way, even smallest amounts of APIs of less than 1% can be dosed precisely. The system doses, mixes and granulates individual packages, so-called X-keys, which continuously run through the process chain and are discharged successively as granules, tablets, or capsules.

Unique and proven technology

The Xelum platform is based on the robust and proven fluid bed processors that Syntegon has been refining for over 30 years. They cover granulation and drying in the same process chamber. This eliminates the need to transfer wet granulate, benefitting the system’s reliability. Xelum achieves high granulation yields with the desired characteristics – including unimodal particle size distribution, as well as excellent flow and tableting properties. The platform further ensures lower production costs and high flexibility. The same holds true for the Xelum R&D and pilot unit, your point of entry into continuous manufacturing.



Xelum R&D

Our Xelum R&D is your ideal start into continuous manufacturing.

Since it uses exactly the same components as the Xelum production platform, process parameters can be directly transferred 1:1 without scale-up. This is valid for dosing, blending, and granulation. You can develop formulations for both batch and continuous manufacturing on the same machine, starting from 250 g. Xelum R&D can run clinical trial and pilot batches at a rate of 10 kg/h. The user-friendly controls of the system is complemented by a practical, automated DoE support. As a fully contained unit, it is also perfectly suited for the development of high potent APIs.


Xelum production line

If you are looking for a continuous production line with a small footprint, flexibility and fast product changeovers, look no further!

Our Xelum production unit uses only 1/3 of the production space of a comparable batch production, saving important cleanroom space, reducing energy costs drastically. The modular set-up allows you to integrate tableting and capsuling. Next to fluid bed granulation also other processes like direct compression are possible. All process parameters can be transferred 1:1 from the Xelum R&D since both machines share the exactly the same components. This eliminates the need for time and cost-intensive scale-up. With a nominal throughput of 30 kg/h, it is an ideal companion for your pilot and production-scale manufacturing.

Features of our continuous manufacturing technology

Our simplified process concept includes smart controls that keep your process within specification. They eliminate the need for complex measurement technology while ensuring consistently high product quality.


Use case scenarios

Outstanding granule quality

Whether you compress granules into tablets or fill them into capsules or sachets, e.g. for nutraceuticals – our Xelum achieves outstanding quality for any dosage form.

Tablets at their best

Outstanding granule properties like smooth flowability and an ideal particle size distribution result in excellent compression characteristics – even at very low API concentration, e.g. for cancer therapy.

Yes we capsule

Granules, pellets and mini tablets are perfectly suitable for fixed-dose or personalized combination capsules, e.g. anti-infective drugs. Our Xelum ensures optimum quality of the individual components
