What we do

As an experienced and competent contract manufacturer for solid pharmaceutical forms, we offer you the highest level of safety and quality awareness in every production step right through to the end product.

The strength of our site lies primarily in the modern structure of our division of tasks: small teams allow us to design our processes flexibly. Added to this is the comprehensive know-how of our approximately 100 employees: be it the specialist knowledge of the substances used or the expertise in handling our specially designed plant parks.

Tabletting and blistering

We have modern facilities for the production of tablets and their proper packaging in blisters. The heart of tablet production is the state-of-the-art blister line – this packing all common tablet formats at a speed of up to 400 blisters per minute

Every year, we press between 500 million and one billion hormone tablets in various dosages – also combined with iodine – which are used to treat hypothyroidism and hyperthyroidism.

The individual active substance composition of our hormone tablets varies depending on the intended use and target country, so that we can offer appropriate preparations for the markets we supply.

Sachet production

Different techniques are used in the processing of granulates and powders containing active ingredients. For example, we use compaction to improve the flow behaviour of the powders. One of our main products (acetylcysteine in powder form) is manufactured using a direct mixing process. The filling of highly effective granulates and powders into sachets is done on four modern packaging lines, which give us a high degree of flexibility in terms of filling quantities and sachet sizes. Prepackages can be printed with variable data, serial numbers and crypto codes. Aggregation is also possible.

Up to half a billion sachets can be produced annually in our sachet packaging department. Examples include high-dose medicines such as cough expectorants or products for diet management such as glucose-electrolyte mixtures.

Our quality standards

We meet all legally prescribed requirements for the production of both medicinal products and food supplements such as balanced diets. Accordingly, we undergo all legally required audits by the authorities to ensure high quality at all times. In addition, we provide our business partners with insights into our processes, which comply with the GMP (Good Manufacturing Practice) guidelines, in regular audits.

Laboratory analyses

In addition to carrying out routine and industry-standard quality tests, we also develop new analytical methods and conduct stability tests for our third-party customers. Recipe adaptations and improvements, scale-up trials and technical transfers are also part of our product portfolio. 

This allows us to offer the complete portfolio of a modern pharmaceutical company in the laboratory area.

Our Services

What we also offer

Our cooperation partners appreciate us for our customer-oriented approach: We offer a comprehensive service package that goes beyond pure production and is tailored to individual customer needs.

Product development

When it comes to developing new generics, we offer a comprehensive service to work out potent formulations. Among other things, this includes appropriate reformulations or the production of pilot batches and clinical trial samples.

Optimisation of manufacturing processes

We also further develop existing formulations for the benefit of our customers. This includes, for example, the optimisation of excipient compositions, variation of the active ingredient dose or the addition of a new flavour correction.

Pilot batches

We can produce pilot-scale batches during the approval process – easily scalable to larger quantities. We also offer clinical trial samples.

Stability tests

Product-accompanying studies in our fully equipped laboratories guarantee the consistent quality of our medicinal products.

Packaging and order picking

The various products are packaged directly on site by our packaging lines in compliance with GMP – whether in sachets or blisters. Our all-round service also includes on-time order processing, order picking and supply chain planning.


We have sufficient storage facilities, both at the site itself and in our nearby external warehouse. For very large volumes, we can access additional space via the Aristo Pharma Group's esparma Pharma Services logistics centre near Magdeburg.
