The hydrochloride salt of a piperidine derivative with neurocognitive-enhancing activity. Donepezil (Aricept) reversibly inhibits acetylcholinesterase, thereby blocking the hydrolysis of the neurotransmitter acetylcholine and, consequently, increasing its activity. This agent may improve neurocognitive function in Alzheimer's disease, reduce sedation associated with opioid treatment of cancer pain, and improve neurocognitive function in patients who have received radiation therapy for primary brain tumors or brain metastases. Donepezil (Aricept) is the most prescribed Alzheimer's disease therapy worldwide.

Decision Resources, one of the world's leading research and advisory firms for pharmaceutical and healthcare issues, finds that, for the treatment of moderate to severe Alzheimer's disease, a combination therapy that delays nursing home admission at 19 months would earn 43 percent patient share, according to surveyed U.S. neurologists. In comparison, in Europe, such an agent would earn a slightly lower patient share of 30 percent, according to surveyed European neurologists. This lower share estimate is possibly a result of higher price sensitivity of European markets.
Scientists have determined that a new instrument known as PIB-PET is effective in detecting deposits of amyloid-beta protein plaques in the brains of living people, and that these deposits are predictive of who will develop Alzheimer's disease.
Decision Resources, one of the world's leading research and advisory firms for pharmaceutical and healthcare issues, finds that, if Pfizer/Medivation's Dimebon shows efficacy in two ongoing clinical trials in moderate to severe Alzheimer's disease that is equivalent to the impressive clinical trial data it has already shown to date in mild to moderate patients, these positive data would promote the use of Dimebon throughout the course of the disease.
