In the Treatment of Alzheimer’s Disease, Polypharmacy Increases Across Lines of Therapy, According to New Analysis from Decision Resources
BURLINGTON, Mass.--(BUSINESS WIRE)-- Decision Resources, one of the world’s leading research and advisory firms focusing on pharmaceutical and healthcare issues, finds that the acetylcholinesterase inhibitor (AChEI) donepezil (Eisai/Pfizer’s Aricept, generics) and Forest Laboratories’ N-methyl-D-aspartate (NMDA) receptor antagonist Namenda lead all other therapies approved for Alzheimer’s disease by a wide margin in the treatment of newly diagnosed Alzheimer’s disease patients. According to analysis from Treatment Algorithms in Alzheimer’s Disease, AChEIs are the most frequently prescribed therapy for the treatment of Alzheimer’s disease, with donepezil capturing the majority of patient share in the class. Meanwhile, Namenda, which is approved for the treatment of moderate to severe Alzheimer’s disease in the United States, is often prescribed in combination with AChEI therapy.
The analysis finds that Namenda captures a modest 15.9 percent patient share in the first line but increases to 40.9 percent in the second line among newly diagnosed patients moving to each line of therapy within a year of treatment initiation.
The analysis also finds that in the treatment of Alzheimer’s disease, polypharmacy increases across the lines of therapy, from modest polypharmacy in the first line (118.4 percent total patient share) to 176.3 percent in the second line and 188.5 percent in the third line.
“Often, Alzheimer’s disease patients initiate treatment with an AChEI and will receive AChEI therapy continually; other therapies are added if the disease progresses or if comorbid conditions such as depression are present,” said Decision Resources Analyst Georgiana L. Kuhlmann, S.M. “While the increase in patient share for Namenda in the second-line reflects its frequent off-label use as an adjunctive therapy to an AChEI in the milder stages of the disease, it could also reflect the worsening of patients’ disease, and as Namenda is approved for the treatment of moderate to severe Alzheimer’s disease, physicians may feel it is appropriate to prescribe Namenda as a monotherapy at that time.”
