ABSTRACT
Objective : Parkinson’s disease (PD) is a disease treated by polytherapy. This time, the authors report the role of pharmacists in one of the few Parkinson’s disease facilities in Japan (https://sunwels.jp/pdhouse/; abbreviated as PD House), which was born from the voices of PD patients. Methods : The backgrounds of 52 patients admitted to the PD House and prescriptions for them were analyzed to mainly clarify: the percentages of patients aged 75 or over and those using 7 or more prescribed drugs; and frequently used drugs to be carefully administered to the elderly. The approaches provided by pharmacists through interprofessional collaboration were also analyzed. Results : The percentages of patients aged 75 or over and those receiving benefits for individuals requiring care were 71.2 and 92.3%, respectively. Those using 7 or more prescribed drugs accounted for 75.0%. In multidisciplinary collaboration, pharmacists were involved in not only pharmacotherapy but also nutritional evaluation of patients with severe nutritional disorders, proposal of appropriate nutritional therapy, understanding of swallowing function, and appropriate medication teaching. Conclusion : The actual situation of PD patients, where they used multiple drugs, and their backgrounds suggest that interprofessional collaboration is indispensable for PD treatment, and the roles of pharmacists were shown to be important.
