Why was it done?

According to Spanish guidelines, medication deprescription would be recommended in the following situations: in the advanced or terminal phase of the disease with a global loss of cognitive and/or functional abilities; in patients who do not experience any benefit; in the presence of intolerable adverse effects or interactions with concurrent treatments. The dose will be progressively reduced every 4 weeks.

What was done?

We designed a project to deprescribe drugs used for dementia in patients at one of the sociosanitary centers (SSC) affiliated with our hospital. The drugs currently used in Spain are: donepezil, rivastigmine, and galantamine for mild to moderate stages, and memantine for moderate to severe stages.

How was it done?

Pharmacists conducted a search using the Savac® pharmaceutical management programme among all residents of the SSC who were prescribed anti-dementia drugs. Once eligible patients were identified, medical team was notified through the electronic prescription programme.

What has been achieved?

According to the previously detailed criteria, there were a total of four eligible patients: one of them was on rivastigmine patch treatment, and the other three were on oral memantine. The results in the first month were not very positive, as an attempt to withdraw memantine from one patient had to be reversed due to aggression issues. Another patient on memantine sadly passed away, and the remaining two, on memantine and rivastigmine, continued with the medication due to potential benefits.

After 10 months of work, the results have been quite promising, and we have successfully completed more withdrawal protocols for other CSS patients. Medication was deprescribed for three patients: one on donepezil and two on memantine. Another patient on rivastigmine is currently in the dose reduction phase.

What next?

Our goal is to achieve the appropriate prescription of anti-dementia drugs, in order to maximise benefits for patients while minimising adverse effects and rationalising public resources.
