Pyrimido- and imidazo-pyridoindole derivatives, in the form of racemates or optically active isomers, of formula: ##STR1## in which n=0 or 1, R.sub.1 =H, Hal, alkyl or alkoxy or CF.sub.3, R.sub.2 =H, alkyl, cycloalkyl-alkyl, cycloalkyl, N,N-dialkylaminoalkyl or phenyl, R.sub.3 =H or alkyl and R.sub.4 =H, alkyl or benzyl are useful as anti-anoxia or psychotropic agents in therapy. They are prepared by cyclizing a compound of formula: ##STR2## wherein R.sub.5 is alkyl, by heating it in an acidic medium, such as ethanolic hydrogen chloride.
