  • Patent number: 4216216
    Abstract: Compounds of general formula ##STR1## are disclosed wherein appropriate substituents for R.sup.1, R.sup.2 to R.sup.5, R.sup.6, A, Q, X, and Z are defined for these novel hexahydropyrimidines.

Because of the highly effective serotonin antagonistic activity in combination with a strong inhibiting effect on thrombocyte aggregation and good compatibility these compounds are effective in treating migraine. Additionally, the compounds also exhibit an anti-histamine activity, cause an increase in erythrocyte fluidity, a psychotropic activity, a weak bradykinin antagonism and hypotensive effects.
