A (fused) benz(thio)amides of the general ##STR1## (wherein, symbol A represents a single bond or a group of methylene, ethylene, trimethylene, tetramethylene, vinylene, propenylene, butenylene, butadienylene or ethynylene group optionally being substituted by one, two or three of straight or branched alkyl groups(s) of from 1 to 10 carbon atom(s) and/or phenyl group(s); Symbol B represents (i) a heterocyclic ring of from 4 to 8 members containing one, two or three hetero atoms selected from oxygen, nitrogen and/or sulphur atom(s), wherein the ring may optionally be substituted by group(s) of oxo, thioxo and/or hydroxy group(s) with the exclusion of a ring of the formula: ##STR2## Symbol T represents an oxygen atom or a sulphur atom; R.sup.1 represents a group of general formula: (i) ##STR3## (ii) ##STR4## or (iii) ##STR5## or (iv) a straight or branched alkyl, alkenyl or alkynyl group of from 1 to 20 carbon atom(s); (wherein R.sup.5 and R.sup.6 independently represent a hydrogen atom or a halogen atom or a straight or branched alkyl, alkenyl or alkynyl group of from 1 to 20 carbon atom(s) being unreplaced or replaced one, two, three, four or five of optional carbon atom(s) by oxygen atom(s), sulphur atom(s), halogen atom(s), nitrogen atom(s), benzene ring(s), thiopene ring(s), naphthalene ring(s), carbocyclic ring(s) of from 4 to 7 carbon atom(s), carbonyl group(s), carbonyloxy group(s), hydroxy group(s), carboxy group(s), azido group(s) and/or nitro group(s); R.sup.2 represents a hydrogen atom or a straight or branched alkyl group of from 1 to 6 carbon atom(s); R.sup.3 represents a hydrogen atom, a halogen atom, a hydroxy group, a nitro group, a group of general formula: --COOR.sup.7 (wherein R.sup.7 represents a hydrogen atom or a straight or branched alkyl group of from 1 to 6 carbon atom(s)) or a straight or branched alkyl, alkoxy or alkylthio group of from 1 to 6 carbon atom(s); R.sup.4 represents (i) when symbol B represents a closed ring, a group of general formula: ##STR6## (wherein symbol U represents an oxygen atom or a sulphur atom. R.sup.8 represents a hydrogen atom or a straight or branched alkyl group of from 1 to 6 carbon atom(s), n and m represent an integer of from 1 to 10, respectively, p and q represent zero or an integer of from 1 to 10, respectively) or non-toxic salts thereof posses an antagonistic activity on leukotrienes (SRS), inhibitory activity of 5.alpha.-reductase, on phospholipase and on aldose reductase and are therefore useful for the prevention and/or treatment for diseases induced by leukotrienes, 5.alpha.-reductase, phospholipase and aldose reductase in mammals, especially human beings.
