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.

Methysergide is a semisynthetic ergot alkaloid ergometrine derivative, introduced in pharmacotherapy for migraine prophylaxis as a specific serotonin (5HT) receptor antagonist. Methysergide is not just a 5HT2 antagonist, it is also a 5HT1 agonist. Open and controlled studies attest to

1. The receptor mediating the long-lasting hypotensive effect of intravenous (i.v.) 5-hydroxytryptamine (5-HT) in the rat was originally classified as 5-HT1-like. Since some pharmacological properties of this receptor are closely similar to those for the cloned 5-ht7 receptor, the present

We used optogenetics to determine the global respiratory effects produced by selectively stimulating raphe obscurus (RO) serotonergic neurons in anesthetized mice and to test whether these neurons detect changes in the partial pressure of CO(2), and hence function as central
