About this page

You may find some outdated terminology or broken links on this page.
However, this page still supports good pharmacy practice.


The Royal Pharmaceutical Society has been working together with stakeholders to improve patient outcomes and patient-centred care with the better use of multi-compartment compliance aids (MCA), also known as monitored dosage systems (MDS).

It's important that the assessment and selection of intervention options to help maintain healthy independent living are be patient-centred, therefore the use of MCA must not be regarded as a universal solution.

This section of our website has been created as a repository of MCA information where our work on MCA can be downloaded, and links to other key related documents impacting upon the best-use of MCA are available.
