Galantamine versus risperidone for agitation in people with dementia: a randomized, twelve-week, single-center study.

AIMS: To examine the effects of galantamine and risperidone on agitation in patients with dementia.

METHODS

A total of 100 patients with dementia and neuropsychiatric symptoms (mean age ± SD: 78.6 ± 7.5 years; 67% female) were included in this 12-week, randomized, parallel-group, controlled, single-center trial. The participants received galantamine (n = 50; target dose: 24 mg) or risperidone (n = 50; target dose: 1.5 mg) for 12 weeks.

RESULTS

Both galantamine and risperidone treatment resulted in reduced agitation. However, risperidone showed a significant advantage over galantamine both at week 3 (mean difference in total Cohen-Mansfield Agitation Inventory score: 3.7 points; p = 0.03) and at week 12 (4.3 points; p = 0.01).

CONCLUSIONS

Agitation improved in both groups, even if the treatment effects were more pronounced in the risperidone group; however, the effects on cognition and other aspects of tolerability were stronger with galantamine.
