Uses

1、Ergotamine(113-15-5) is used medicinally for treatment of acute migraine attacks (sometimes in combination with caffeine), and to induce childbirth and prevent post-partum haemorrhage.
2、In high doses ergotamine is conducive to vascular stasis, thrombosis and gangrene. It can increase uterine contractivity and occasionally is used therapeutically immediately post-partum to decrease uterine bleeding.

Specification

Mechanism of action
The mechanism of action of ergotamine is complex.The molecule shares structural similarity with neurotransmitters such as serotonin, dopamine, and adrenaline and can thus bind to several receptors acting as an agonist. Ergotamine also has effects on the dopamine and noradrenaline receptors. It is its action on the D2 dopamine and 5-HT1A receptors that can cause some side effects.
