Method for treating an inflammatory disease

Compounds of the formula and quaternary ammonium ions thereof, wherein R.sup.1 and R.sup.2 are the same or different and are carbocyclic aryl or aromatic heterocyclic; A is methylene, carbonyl or sulfonyl; B is a single bond, C.sub.1 -C.sub.4 alkylene or C.sub.2 -C.sub.4, alkenylene; D is oxygen; E is C.sub.2 alkylene; G is C.sub.1 -C.sub.4 alkylene or C.sub.2 -C.sub.4 alkenylene; and L is --C(R.sup.4)(R.sup.5), wherein R.sup.4 and R.sup.5 together with the carbon atom to which they are attached represent a C.sub.5 -C.sub.10 cycloalkyl or a C.sub.5 -C.sub.10 heterocyclic. Especially preferred are compounds wherein L represents ##STR1## wherein J is a C.sub.1 -C.sub.6 alkylene; Ar is a ring carbocyclic or aromatic heterocyclic and S*.fwdarw.O is a sulfoxide in which the sulfur atom is in the 5-configuration. The compounds have tachykinin receptor antagonist activity and exhibit an activity against both the NK.sub.1 and NK.sub.2 receptors.
