Heterocyclic dihydroxyquinoxaline compounds having the formula ##STR1## wherein R.sup.1 is hydroxy, alkoxy, aryloxy, aralkyloxy, cycloalkylalkoxy, cycloalkoxy, or acyloxy; R.sup.5 and R.sup.6 together form a further fused ring, which is substituted with hydrogen, halogen or CN, and R.sup.7 and R.sup.8 independently are hydrogen, NO.sub.2, halogen, CN, SO.sub.2 NR'R', SO.sub.2 R', CF.sub.3, or OR', wherein R' is hydrogen or C.sub.1-4 -alkyl; or R.sup.7 and R.sup.8 together form a further fused ring, which is substituted with hydrogen, halogen or CN, and R.sup.5 and r.sup.6 independently are hydrogen, NO.sub.2, halogen, CN, SO.sub.2 NR'R', SO.sub.2 R', CF.sub.3, or OR', wherein R' is hydrogen or C.sub.1-4 -alkyl. The invention also relates to a method of preparing the compounds, pharmaceutical compositions thereof, and their use. The compounds are useful in the treatment of indications caused by hyperactivity of the excitatory neurotransmitters, particularly the quisqualate receptors, and especially as neuroleptics.
