Dihydroergocristine is an ergot alkaloid that has an partial agonist activity on dopaminergic and alpha-adrenergic receptors and antagonist activity on serotonin receptors. The drug was approved by FDA in combination with other alkaloids (dihydroergocornine, dihydro-alpha-ergocryptine and dihydro-beta-ergocryptine mesylate salts) under the name Hydergine for the treatment of dimentia and cerebrovascular insufficiency.

Sample Use Guides

In Vivo Use Guide

The recommended dosage (in form of hydergine tablets containing dihydroergocornine, dihydroergocristine, dihydro-alpha-ergocryptine and dihydro-beta-ergocryptine mesylate salts in an approximate weight ratio of 1:1:1) in the US is 1 mg three times daily. In Europe and Japan, up to 12 mg of hydergine daily have been used without serious adverse effects.

Route of Administration: Oral

In Vitro Use Guide

C-1300 neuroblastoma cells were incubated with dihydroergocristine at concentration of 2 uM. In another experiment dihydroergocristine was added to the perfusion medium of the isolated rat brain in a concentration of 5 uM. In both experiments the drug caused changes in the concentrations of the high-energy phosphates.
