Lack of Efficacy of Hydergine in Patients with Alzheimer's Disease

Abstract
There is no effective pharmacologic treatment for Alzheimer's disease, the most common dementing illness in the United States. Hydergine, a combination of ergoloid mesylates, is the only approved medication for Alzheimer's disease, but despite widespread use its efficacy remains to be established. We conducted a clinical trial of Hydergine-LC, a newer preparation of ergoloid mesylates in the form of a liquid in a capsule (LC) that may have greater bioavailability, to determine its value in patients with Alzheimer's disease.
