Abstract
The invention relates to basic quaternary amides of formula <IMAGE> in which - Ar represents an optionally substituted mono-, di- or tricyclic heteroaromatic or aromatic group; - T represents a direct bond, a hydroxymethylene group, an alkoxymethylene group in which the alkoxy group is C1-C4 or a C1-C5 alkylene group; - Ar' represents a phenyl which is unsubstituted or substituted one or a number of times, a thienyl, a benzothienyl, a naphthyl or an indolyl; - R represents hydrogen, a C1-C4 alkyl, an omega -(C1-C4)alkoxy(C2-C4)alkyl or an omega -(C1-C4)alkanoyloxy(C2-C 4)alkyl, - Q represents hydrogen; - or else Q and R, together, form a 1,2-ethylene, 1,3-propylene or 1,4-butylene group; - Am<(+)> represents the radical <IMAGE> in which X1, X2 and X3, together and with the nitrogen atom to which they are bonded, form an azabicyclic or azatricyclic system optionally substituted by a phenyl group; - A<(-)> is a pharmaceutically acceptable anion. These compounds are useful in the preparation of medicaments intended for the treatment of pathologies involving the tachykinin system.
