A class of N,N'-cycloalkyl/alkyl benzamides of certain 4H-imidazo[4,5-b]pyridine compounds is described for treating cardiovascular and immuno-inflammatory related disorders mediated by platelet activating factor (PAF). Compounds of particular interest are those of the formula: ##STR1## wherein R.sup.1 is selected from hydrido, alkyl, hydroxyalkyl, alkoxyalkyl, phenyl, halophenyl, pyridinyl, alkylsilyloxyalkyl, amino, monoalkylamino, dialkylamino, aminoalkyl, monoalkylaminoalkyl and dialkylaminoalkyl; wherein each of R.sup.5, R.sup.6, R.sup.7 and R.sup.8 is independently selected from hydrido, hydroxy, alkyl, alkoxy, fluoro, chloro, bromo, haloalkyl, alkylthio, alkoxyalkyl, hydroxyalkyl, alkylthioalkyl, cyano, amino, monoalkylamino and dialkylamino; wherein each of R.sup.9 and R.sup.10 is independently selected from hydrido, alkyl, cycloalkyl, bicycloalkyl, heterocyclic, heterocyclicalkyl, aryl, alkenyl and cycloalkenyl, and wherein any of said R.sup.9 and R.sup.10 substituents may be further substituted with one or more groups selected from linear or branched lower alkyl, lower alkoxy, fluoro, chloro and bromo; or a pharmaceutically-acceptable salt thereof.
