Sansert® (methysergide maleate) is a partially synthetic compound structurally related to lysergic acid butanolamide, well-known as methylergonovine in obstetrical practice as an oxytocic agent.

Methylation in the number 1 position of the ring structure enormously enhances the antagonism to serotonin which is present to a much lesser degree in the partially methylated compound (methylergonovine maleate) as well as profoundly altering other pharmacologic properties.
