The invention relates to a group of tertiary 2,5-dialkyl-3-phenylpiperidine derivatives, having opiate-antagonistic activity represented by general formula 4, ##STR1## wherein A.sub.1 is hydrogen, an optionally esterified hydroxyl group or mercapto group, a group NHA.sub.8 or --CONHA.sub.8, wherein A.sub.8 is hydrogen, alkyl having 1-6 C-atoms or alkylcarbonyl having 2-7 C-atoms; A.sub.2 is hydrogen or, when A.sub.1 is hydrogen, one of the other meanings of A.sub.1, or A.sub.1 and A.sub.2 together with the 2 carbon atoms of the benzene ring,constitute a heterocyclic group which consists of five or six ring atoms and which comprises a group --NH-- and optionally as a second hetero atom may comprise an oxygen atom, sulphur atom or nitrogen atom; A.sub.3 and A.sub.4 independently of each other are straight or branched alkyl or alkenyl having 1-6 C-atoms; A.sub.5 is a straight or branched alkylene chain having 2-8 C-atoms; X is the carbonyl group or ketalized carbonyl group or the group>CHOH, --CONH--, --NHCO--, methylene, >CHC.sub.6 H.sub.5, or an oxygen atom or sulphur atom; A.sub.6 is an alkyl group, cycloalkyl group or cycloalkylalkyl group having at most 10 C-atoms and optionally substituted with one or more groups A.sub.7, or is a phenyl group or phenylalkyl group having 1-4 C-atoms in the alkyl group and optionally substituted with one or more groups A.sub.7, and A.sub.7 is alkyl, alkoxy or alkylthio having 1-4 C-atoms, amino, mono- or dialkylamino having 1-4 C-atoms per alkyl group, hydroxyalkyl, alkylcarbonyl, alkylaminocarbonyl or alkoxycarbonyl having 1-4 C-atoms in the alkyl group, nitro, cyano, halogen, trifluoromethyl, trifluoromethoxy, alkylsulphonyl having 1-4 C-atoms, or aminosulphonyl. These compounds have a pure opiate-antagonistic activity, i.e. without an agonistic activity component.
