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 formula (I) wherein R1 is selected from hydrido, alkyl, hydroxyalkyl, alkoxyalkyl, phenyl, halophenyl, pyridinyl, alkylsilyloxyalkyl, amino, monoalkylamino, dialkylamino, aminoalkyl, monoalkylaminoalkyl and dialkylaminoalkyl; wherein each of R5, R6, R7 and R8 is independently selected from hydrido, hydroxy, alkyl, alkoxy, fluoro, chloro, bromo, haloalkyl, alkylthio, alkoxyalkyl, hydroxyalkyl, alkylthioalkyl, cyano, amino, monoalkylamino and dialkylamino; wherein each of R9 and R10 is independently selected from hydrido, alkyl, cycloalkyl, bicycloalkyl, heterocyclic, heterocyclicalkyl, aryl, alkenyl and cycloalkenyl, and wherein any of said R9 and R10 substituents may be further substituted with one ore more groups selected from linear or branched lower alkyl, lower alkoxy, fluoro, chloro and bromo; or a pharmaceutically-acceptable salt thereof.
