Description

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.

Chemically, methysergide maleate is designated as ergoline-8-carboxamide, 9,10-didehydro-N-[1-(hydroxymethyl)propyl]-1,6-dimethyl-, (8ß)-, (Z)-2-butenedioate (1:1) (salt).

Its structural formula is:

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.

Active Ingredient: methysergide maleate, USP.

Inactive Ingredients: acacia, carnauba wax, colloidal silicon dioxide, FD&C Blue #1, FD&C Yellow #5, gelatin, lactose, malic acid, povidone, sodium benzoate, starch (corn), stearic acid, sucrose, synthetic black iron oxide, talc, and titanium dioxide.
