Awards & Accreditations

ISO 13485:2016

In December 2017, Merxin Ltd was assessed and certified as meeting the requirements of ISO 13485:2016 for the Design, Development and Supply of inhalers.

Our ISO 13485:2016 accreditation recognises the quality management systems that Merxin have in place, reflected in the quality of standards across our products and services. Merxin is qualified to supply regulated markets such as the EU, Japan, Canada, Australia and US.

FDA substitutability of MRX003

In February 2017, MRX003, our capsule DPI inhaler was given the nod by the FDA as a suitable generic device with which to file a 505j ANDA of Spiriva HandiHaler (tiotropium).

The origins of Merxin are in the generic world, we design device that would accelerate generic filing: performance and handling have to be matched to the originator product, while avoiding existing I.P. Merxin excels at this. We then take this expertise to making device platforms for new molecules and combinations.

CE marking of MRX003

In December 2017, a version of our Capsule inhaler MRX003 was cleared for CE marking and use in clinical trials.

We do not simply design devices, we make them compliant with the necessary device regulations in EU and US, ready for human use, clinical trials and commercial launch. Pharmaceutical quality is in our DNA.

EU Regional Development Fund Grant

In December 2018, Merxin was awarded a grant from the New Anglia Business Growth Programme - Small Grant Scheme, part funded by the European Regional Development Fund.

The funds were used to accelerate Merxin R&D plans and enabled us to invest in new equipment, Malvern Spraytec and Mitutoyo Metrology, to increase our services to our clients.

We are committed to exceed our customers’ expectation and work and run with them towards filing, approval and launch of their products. The commercial success of our clients is the measure of our success.

Business of the Year awards – 2019

In March 2019, Merxin was named as West Norfolk’s top company.
