Ergot derivatives can treat many different conditions, such as acromegaly, high prolactin levels, Parkinson's disease, diabetes type 2, hemorrhages, and migraines. They work by binding to dopamine receptors. This affects different processes in the body, such as signaling in the brain, blood vessel dilation, and certain hormone levels. Atzumi is only available as a brand name drug.
