Overview

Methysergide (1-methyl-D-lysergic acid butanolamide or UML-491) is a prescription drug formerly used for prophylaxis of cluster headaches/migraine headaches, but is no longer recommended due to retroperitoneal/retropulmonary fibrosis.

Medical uses

Methysergide is used to treat headaches such as migraine and other recurrent throbbing headaches.[1] Methysergide is one of the most effective[2] medications for the prevention of migraine, but not for the treatment of an acute attack.

It is also used in carcinoid syndrome to treat severe diarrhea.[1] It may also be used in the treatment of serotonin syndrome.[3]

Side effects

It has a known side effect, retroperitoneal fibrosis,[4] which is severe, although uncommon. Other severe but uncommon side effects include pleural fibrosis, and subendocardial fibrosis.

In addition, there is an increased risk of left-sided cardiac valve dysfunction.[2][5]

Pharmacology

Methysergide interacts with serotonin (5-HT) receptors. Its therapeutic effect in migraine prophylaxis has been associated with its antagonism at the 5-HT2B receptor.[6] Furthermore, it is an antagonist at the 5-HT2C receptor, while at the 5-HT1A receptor it serves as a partial agonist.[7][8][9] It is known to have partial agonist effects on some of the other 5-HT receptors as well.[10] Methysergide is metabolised into methylergometrine in humans, which is responsible for its psychedelic effects.[11]

History

Methysergide was approved by the U.S. Food and Drug Administration (FDA) in 1962.

Novartis withdrew it from the U.S. market after taking over Sandoz, but currently lists it as a product.[citation needed]

Synthesis
