Abstract: Tricyclic benzazepines having the general formula ##STR1## wherein A together with the .alpha.- and .beta.-marked carbon atoms is a cyclopentene, cyclohexene, furan, dihydrofuran, pyran, dihydropyran, thiophene, oxazole, pyrrole, pyrroline, tetrahydropyridine or dioxole ring, R.sup.1 is H or alkyl, R.sup.2 and R.sup.3 independently are H, alkoxy, halogen, nitro, cyano or hydroxy, or R.sup.2 and R.sup.3 together may form a furan, dihydrofuran, cyclopentene or dioxole ring and R.sup.4 is H, alkoxy, nitro, cyano, hydroxy or halogen, or a pharmaceutically acceptable salt thereof, are useful in treatment of certain disorders in the central nervous system, e.g., psychosis, pain, depression, sleep disturbances, dyskinesia, Parkinson's disease, stroke.

Abstract: A disubstituted piperazine compound having the formula ##STR1## wherein R.sup.1 is halogen, methoxy, C.sub.1-6 -alkyl or trifluoromethyl, and R.sup.2 is methyl or substituted C.sub.1-8 -alkyl, C.sub.3-8 -alkenyl or C.sub.3-8 -cycloalkyl, where substituents may be hydroxy-, keto- or oximino-groups in any position leading to a stable tertiary amine; or R.sup.2 is a straight or branched C.sub.1-8 -alkyl or C.sub.3-8 -alkenyl, which in any position may be substituted as above, but is terminally substituted with one of the following groups: cyano, optionally C.sub.1-4 -alkoxy-substituted C.sub.1-4 -alkoxy, dimethoxy, optiontionally substituted phenoxy, phosphonic acid, thienyl, furyl, oxazoline, isoxazole, oxadiazole, where the optional substitution is represented by C.sub.1-6 -alkyl or phenyl, provided that when cyano is the only substituent in R.sup.2, R.sup.2 must contain at least four carbon atoms, and pharmaceutically acceptable acid addition salts thereof.
