  • Title: [Influence of nicergoline on the cerebral blood flow and alpha-sympatholytical properties (author's transl)].
    Author: Lievre M, Ollagnier M, Faucon G.
    Journal: Arzneimittelforschung; 1979; 29(8a):1227-31. PubMed ID: 44198.
    Abstract:
    The cerebral vasodilatory effect of 10-methoxy-1,6-dimethyl-ergoline-8 beta-methanol-(5-bromonicotinate) (nicergoline, Sermion) was examined by recording the cardiac output of the vertebral artery in the dog. As from a dosage of 25 micrograms/kg nicergoline increases permanently the cardiac output to a normal or nearly normal level which had been decreased by phenylephrine reducing the increased local vascular resistance. The alpha-sympatholytical properties of nicergoline were more precisely proved by reducing the reactive increase in blood pressure after epinephrine and norepinephrine (3 micrograms/kg) by administration of nicergoline in 3 doses (25, 50 and 100 micrograms/kg). The same method was used with phentalamine in dosages of 125, 250 and 500 micrograms/kg. The statistical comparison of the results obtained with both substances shows that the ratio of equiactive doses is about 3:1 in favour of nicergoline.
