Compounds of the formula ##STR1## wherein Z is --CH.sub.2 CH.sub.2 -- or --CH.dbd.CH--, and R is methyl, ethoxycarbonylmethyl or ##STR2## wherein ##STR3## is methylamino, n-propylamino, isopropylamino, dimethylamino, di(n-propyl)amino, morpholino, pyrrolidino or hexamethyleneimino. The compounds are prepared by reacting piperazine substituted with R, with 4'-bromomethyl-5,2'-spiro-dibenzocycloheptadi(or tri)ene-(1',3') dioxolan. The compounds possess cough-suppressing, spasmolytic, analgesic, respiratory analeptic, hypotensive, vasodilatory, antiarythmic, antiulcerous, antihistamine, sedative, anti-inflammatory, diuretic and antiserotonine properties.
