Abstract

The invention relates to novel dibenzo[1,2;5,6] cyclohepta pyridine or -pyrrole derivatives, dibenzo[2,3;6,7] oxepino pyridine or pyrrole derivatives, dibenzo[2,3;6,7] thiepino pyridine or pyrrole derivatives and dibenzo[b,f] pyrido or pyrrolo azepine derivatives of general formula: ##STR1## as well as the pharmaceutically acceptable salts and nitrogen oxides thereof, wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 each represent hydrogen, hydroxy, halogen, an alkyl (1-6 C) group, an alkoxy or alkylthio group in which the alkyl group contains 1-6 C-atoms, or a trifluoromethyl group, R.sub.5 represents hydrogen, an alkyl group with 1-6 carbon atoms or an aralkyl group with 7-10 carbon atoms, m is the number 1 or 2, X represents oxygen, sulphur, the group ##STR2## or the group --CH.sub.2 -- and R.sub.6 represents hydrogen or a lower alkyl group (1-4 C), having CNS-depressant activity and excellent antihistamine and antiserotonin activities.
