    A mixture of three different hydrogenated derivatives of ERGOTAMINE: DIHYDROERGOCORNINE; DIHYDROERGOCRISTINE; and DIHYDROERGOCRYPTINE. Dihydroergotoxine has been proposed to be a neuroprotective agent and a nootropic agent. The mechanism of its therapeutic actions is not clear, but it can act as an alpha-adrenergic antagonist and a dopamine agonist. The methanesulfonate salts of this mixture of alkaloids are called ERGOLOID MESYLATES.

    5 Pharmacology and Biochemistry
    5.1 MeSH Pharmacological Classification

    Adrenergic alpha-Antagonists

    Drugs that bind to but do not activate alpha-adrenergic receptors thereby blocking the actions of endogenous or exogenous adrenergic agonists. Adrenergic alpha-antagonists are used in the treatment of hypertension, vasospasm, peripheral vascular disease, shock, and pheochromocytoma. (See all compounds classified as Adrenergic alpha-Antagonists.)

    Dopamine Agonists

    Drugs that bind to and activate dopamine receptors. (See all compounds classified as Dopamine Agonists.)
