What is "ergoloid"

Ergoloid mesylates ( USAN), co-dergocrine mesilate ( BAN) or dihydroergotoxine mesylate, trade name Hydergine, is a mixture of the methanesulfonate salts of three dihydrogenated ergot alkaloids ( dihydroergocristine, dihydroergocornine, and alpha- and beta-dihydroergocryptine).

It was developed by Albert Hofmann (the inventor of LSD) for Sandoz (now part of Novartis).
