Application

Methysergide maleate salt has been used as a serotonin (5HT) receptor antagonist to evaluate the potential systemic effects of methysergide (METH) and 5-HT infusions on production and milk composition in multiparous Holstein cows. It may also be used as a serotonin receptor blocker to identify the serotonergic receptor type involved in the direct excitation of mitral cells in the main olfactory bulb.

Biochem/physiol Actions

Methysergide maleate, also known as sansert, is a semisynthetic ergot alkaloid ergometrine derivative. Methysergide is a serotonin 1(5-HT1) receptor agonist and a nonselective 5-HT2 and 5-HT7 serotonin receptor antagonist. Methysergide maleate is used as a pharmacological agent to treat migraines and other vascular headaches. But, prolonged and uncontrolled use of this drug may cause Leriche′s syndrome, angina pectoris, acute ischemia of the limbs. In addition, gastrointestinal side effects, such as abdominal cramps, nausea, and diarrhea have also been observed in few patients.
