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.
