Treatment options:: The latest evidence with galantamine (Reminyl®)

Vascular dementia (VaD) has a great deal of overlap (in terms of features and symptoms) with Alzheimer's disease (AD). Mixed dementia, or AD with concomitant cerebrovascular disease (AD with CVD), is increasingly being recognized as a distinct clinical condition that occurs with substantial frequency. The robust evidence for the effectiveness of cholinergic treatments such as galantamine (Reminyl(R)) in AD suggests its potential use in the treatment of dementias related to CVD, and preclinical evidence supports this rationale. Galantamine, which has a unique dual cholinergic mode of action, may be of particular benefit in VaD and AD with CVD. For example, behavioral symptoms, which can be more severe in VaD than in AD and are important determinants of the impact of dementia, may be especially benefited by galantamine. This results from its potential to modulate systems involving other neurotransmitters such as 5-HT (serotonin) and dopamine, which affect mood and emotional balance. The results of a recent landmark clinical trial with galantamine in patients with VaD, or AD with CVD, indicate that galantamine produces benefits across a broad range of symptoms of dementia in both patient populations. Significant cognitive improvements over 6 months, long-term maintenance of cognition for at least 12 months, and global benefits, as well as efficacy in both behavioral and functional symptoms, indicate efficacy with galantamine that is so far unsurpassed by any other drug treatment for dementia. Galantamine therefore has potential to benefit a wide range of patients with dementia in the clinic. (C) 2002 Elsevier Science B.V. All rights reserved.
