Starting out as a training resource for students at Bath University, this firm became a commercial operation in 2006 when Richard Wastnage, 53, Christopher Watt, 49, and Maria Watt, 48, spun it out to form Bath ASU. It prepares specialist medicines individually tailored to patients’ needs, including intravenous chemotherapy doses and patient-controlled pain relief. In 2010 the group launched sister business Pharmaxo, which provides traditional pharmacy and hi-tech homecare services. Sales hit £152.7m in 2017 thanks to the success of new products. That year work was completed on a production facility featuring the UK’s biggest aseptic clean room.
