Novel derivatives of isosorbide mononitrate and its pharmaceutically acceptable salts, which have vasodilating activity with a reduced effect of tolerance, of the general formula (I) in which A and B individually represent any of the groups -ONO2 and -Z-CO-R, wherein Z is an oxygen atom or sulphur atom and R is an alkyl C1-C4 group, an aryl group or an aralkyl group, eventually substituted, or the group in which R<1 >is hydrogen, or an alkyl C1-C4 group, an aryl group or an aralkyl group, eventually substituted, with the proviso that one of A or B is always -ONO2, but never both of them at the same time, when Z is an sulphur atom R is an alkyl C1-C4 group, an aryl group or an aralkyl group, eventually substituted, and when Z is an oxygen atom R is the group
