About US


Callisto Pharma Group has grown from the formation, in 2003, of Callisto Regulatory Consulting Ltd, which provided regulatory and technical support to pharmaceutical manufacturers. Callisto has developed into a consultancy group that can provide a complete range of technical services across the whole supply chain within multiple regulated sectors including human, veterinary and herbal medicines, borderline products, biocides, medical devices and food supplements.

We work across the UK, Europe, and the rest of the world for clients operating in highly regulated sectors, ranging from global multi-nationals to single product licence holders.

Within the group we can provide product release and QP Technical support to manufacturers and licence holders. The group holds both an MIA and ManA granted by the MHRA to enable us to support clients wishing to import Licensed Human & Veterinary products into the UK. 

An Irish group company was established 2018 in response to the UK’s Brexit preparations to ensure continued service for many of our clients. We now also hold an MIA, VIA and WDA granted by the HPRA and, in conjunction with our UK licences we maintain a European (EEA) footprint.
