Dihydroergotoxine/Ergoloid Mesylates

Please note, this OEL/ADE monograph also applies to Ergoloid mesylates/Dihydroergotoxine mesylate (CAS RN 8067-24-1). Dihydroergotoxine is a mixture of three different hydrogenated derivatives of ergotamine. These are dihydroergocristine (CAS 17479-19-5), dihydroergocornine (CAS 25447-65-8), and dihydroergocryptine (CAS 25447-66-9). Dihydroergotoxine has been proposed to be a neuroprotective agent and a nootropic agent. The methanesulfonate salts of this mixture of alkaloids are called ergoloid mesylates. Ergoloid mesylates are also known as dihydroergotoxine mesylate or codergocrine mesylate. Dihydroergocryptine mesylate exists as a mixture of alpha (α) and beta (β)-isomers. Ergoloid mesylate is a nootropic used as adjunct in the symptomatic treatment in individuals over sixty years of age who manifest signs and symptoms of an idiopathic decline in mental capacity and mild/moderate dementia. It is also prescribed for cognition enhancement in well persons of all ages and for the treatment of cerebrovascular insufficiency.
