HIDE SMILES / InChI
Metergotamine (MY-25 or 1-methyl-ergotamine-bitartrate) is a derivative of ergotamine and belongs to peptide alkaloids. It exerts a dampening effect on vessels, in that relaxation is brought about in contracted vessels, whereas contraction is brought in dilated vessels. Metergotamine was being studied in migraine prophylaxis.
