Heterocyclocyclyicarbonyl derivatives of urea for use in dissolving gallstones, having the formula RCONHCONR1R2, wherein R is pyridyl, monochloro-pyridyl, quinolyl, furyl, thiazolyl, 4-methyl-5-thiazolyl, 4-methyl-5-oxazolyl, isothiaiolyl, 3-methyl-5-isothiazolyl, 3-(1,2-benzoisothiazolyl), 5-methyl-3-isoxazo(yl, 3-methyl-5-isoxazolyl, 5-meihyl-3-phenyl-4-isoxazolyl, 3-(1,2,5-thiadiazolyl) or 4-(1,2,3-thiadiazolyl); R is hydrogen, alkyl having from one to ten carbon atoms naphthyl or phenyl; R2 is hydrogen, alkyl having from one to ten carbon atoms, phenyl or phenylalkyl wherein the alkyl has from one to four carbon atoms; or R1 and R2 taken together with the nitrogen to which they are attached form a morpholino, thiomorpholino, 1-(1,2,3,8-tetrahydropyridyl), 1-azacycloheptyl, 1-azacyclooctyl or 3-(2,3,4,5-tetrahydro-3,1-benzazepinyl) group, or a piperidino group optionally substituted with alkyl having from one to four carbon atoms, alkoxy having from one to four carbon atoms, chloro, or phenylalkyl having from one to four carbon atoms in the alkyl group; with the proviso that, where R is a 5-methyl-3-isoxazolyl group, then R' and R2 are taken together with the nitrogen to which they are attached and form a group other than morpholino. These compounds are novel, except for those in which R is pyridyl, R is hydrogen and R2 is hydrogen, methyl or ethyl.
