The global market for combination drugs and donepezil in Alzheimer’s treatment is projected to reach US$ 26.37 billion by 2031, growing from US$ 8.24 billion in 2024 at a CAGR of 13.6% during 2025–2031. Rising Alzheimer’s prevalence, aging populations, and evolving treatment strategies are driving market expansion. While disease-modifying therapies are gaining attention, combination drugs and donepezil remain central to clinical management due to their proven effectiveness, safety, and accessibility.

Role of Donepezil in Alzheimer’s Care

Donepezil, a cholinesterase inhibitor, continues to serve as a first-line therapy for mild to moderate Alzheimer’s disease. It works by preventing the breakdown of acetylcholine, a neurotransmitter essential for memory and cognition. Its long-standing clinical use, strong safety profile, and affordability have made it a standard treatment across multiple markets.

The drug’s relevance is further strengthened by its role in combination therapy regimens. Donepezil is often paired with NMDA receptor antagonists such as memantine to enhance cognitive and functional outcomes. Generic availability has expanded its reach, making it a staple in both developed and emerging markets. Patient adherence and consistent prescribing practices ensure stable demand.

Rising Adoption of Combination Drug Therapies

Combination therapies are gaining traction as healthcare providers seek to address the multifactorial nature of Alzheimer’s disease. By targeting multiple pathways simultaneously, these therapies offer improved symptom control compared to monotherapy. Fixed-dose combination formulations simplify dosing, increase compliance, and reduce caregiver burden, making them an attractive treatment option.

Clinical guidelines increasingly recommend combination therapy for moderate and advanced stages of the disease. Pharmaceutical companies are responding by developing innovative formulations that integrate cholinesterase inhibitors and NMDA receptor antagonists, ensuring better patient outcomes and extending the commercial life of existing therapies.
