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.

Serotonergic systems play important roles in modulating stress-induced arousal and vigilance behaviours. The pond snail, Lymnaea, shows multiple defensive vigilance behaviours in response to the stress associated with predator detection. Predator detection elicited by crayfish effluent (CE), increases the time

A progressive and sustained increase in inspiratory-related motor output ("long-term facilitation") and an augmented ventilatory response to hypoxia occur following acute intermittent hypoxia (AIH). To date, acute plasticity in respiratory motor outputs active in the postinspiratory and expiratory phases has

1. The current classification of receptors for 5-hydroxytryptamine (5-HT) is based on functional studies, and encompasses three main receptor types. 2. 5-HT1-like receptors mediate inhibition of release of various neurotransmitters from central and peripheral sites, smooth muscle contraction and relaxation
