Ergotamines
Ergotamines are a group of medications that are derived from ergot fungi and are commonly used to treat migraines and cluster headaches. These medications work by constricting blood vessels in the brain, which helps to relieve the pain and other symptoms associated with these types of headaches. Ergotamines are available in various forms, including tablets, nasal sprays, and injections, and are typically used as a second-line treatment for headaches when other medications have proven ineffective. It is important to note that ergotamines should not be used regularly or in high doses, as they can lead to serious side effects such as ergotism.
