5HT6 Antagonists in the Treatment of Alzheimer's Dementia: Current Progress

Document Type

Abstract

Alzheimer's disease is an important condition with a considerable and unmet disease burden in large need of continued research and more treatment options. The 5HT6 antagonists are a new class of medications to be offered. Because they are pro-cholinergic, these medications are to be used as adjuncts to acetylcholinesterase inhibitors (such as donepezil), further increasing acetylcholine in the central nervous system (CNS). Early trials of the 5HT6 antagonists showed improvements in cognition and activities of daily living when used as adjuncts to current therapies for Alzheimer's dementia. However, recent phase III trials have failed to show a statistically significant improvement in cognitive function. This article will provide a comprehensive review of 5HT6 antagonists in drug development, including some that have been recently discontinued. We will discuss both the successes and failures of this drug class and provide rationale for their continued research and development.
