What are disclosed are pyrrolidinylsulfamoylbenzoic acid compounds of the formula ##STR1## in which R.sup.1 and R.sup.2 denote C.sub.1 -C.sub.4 alkyl and one of the radicals R.sup.1 or R.sup.2 may be hydrogen, R.sup.3 and R.sup.3' denote hydrogen or C.sub.1 -C.sub.4 alkyl or together denote a C--C linkage, R.sup.4 and R.sup.4' denote hydrogen, halogen, CF.sub.3, alkyl or C.sub.1 -C.sub.2 alkoxy, hydroxy, amino or dimethylamino in the various positions of the aryl nucleus, or together denote 3,4-methylenedioxy, R.sup.5 and R.sup.6 denote hydrogen, C.sub.1 -C.sub.4 alkyl or benzyl, Ar denotes phenyl or a 5-membered or 6-membered heteroaromatic ring containing a O, S or N atom and X is omitted or denotes oxygen, sulfur, NH, or CH.sub.2, and their pharmaceutically acceptable salts with bases or acids. The compounds and salts have a salidiuretic action and can be used for the treatment of edematous diseases.
