    摘要: Ergoline derivatives of general formula I
    wherein either R₁ represents a hydrogen atom or a methoxy group and R₂ represents a hydrogen atom or R₁ and R₂ taken together represent a chemical bond, and R₃ represents a hydrogen atom, an unsubstituted or substituted nicotinoyl group or a 1-oxo-2-cyclopenten-3-yl group; or a pharmaceutically acceptable salt thereof are active at the Central Nervous System level and useful therefore in the treatment of cerebral insufficiency and senile dementia.
