Trends of antidementia drugs use in outpatients with Alzheimer’s disease in six major cities of China: 2012–2017

Alzheimer’s disease is a devastating neurodegenerative disease that requires pharmacological intervention. We conducted a descriptive study using pharmacy prescription data of antidementia drugs. Prescription information of 99 541 patients was obtained from 55 hospitals. Overall the number of Alzheimer’s disease outpatients of sampling days increased from 10 239 in 2012 to 20 546 in 2017. The main age range of patients suffering Alzheimer’s disease was 75–84, while the patients aged above 85 was increasing. Nonusers of antidementia drugs, cholinesterase inhibitors (ChEIs) and memantine slowly decreased over the study period. The percentage of patients taking ChEIs and ChEIs-combined memantine increased. The most frequently prescribed ChEI was donepezil. These results are mostly in line with the guideline recommendations and clinical evidence during the study period. Efforts should be made to reduce the number of nonusers and optimize the use of antidementia drugs.
