Abstract
Abstract Heterocyclic amides of the formula: ##EQU1## wherein: X is N or CH; n is O or 1 and R is ##EQU2## wherein: R 1 is hydrogen or methyl, R 2 and R 3 which are the same, are lower alkyl or joined together, represent a polymethylenic chain from C 4 to C 7 optionally including an oxygen atom, and R' is saturated or unsaturated acyclic hydrocarbon radicals from C 1 to C 20 , cycloalkyl from C 3 to C 7 , Ar - A- or ##EQU3## wherein: A is a single bond or a saturated or unsaturated acyclic hydrocarbon chain from C 1 to C 6 optionally including an oxygen atom, and Ar and R" are aromatic, alkoxy aromatic, methylenedioxy aromatic or polymethylenedioxy aromatic. These compounds are used as medicine, especially in the treatment of gastric hypersecretion, gastroduodenal ulcers and central nervous system disorders.
