    • Hydroxytetrahydropyridinelactones of the formula ##STR1## in which R represents a phenyl, naphthyl, thienyl, furyl, pyrryl, pyrazolyl, imidazolyl, oxazolyl, isoxazolyl, thiazolyl, pyridyl, pyridazinyl, pyrimidyl, pyrazinyl, quinolyl, isoquinolyl, indolyl, benzimidazolyl, quinazolyl, quinoxalyl, thionaphthenyl, isothionaphthenyl, chromonyl, thiochromonyl, chromenyl, thiochromenyl, benzoxadiazolyl or benzthiadiazolyl radical, and the stated radicals may carry 1 to 3 identical or different substituents from the group comprising C.sub.1 -C.sub.20 -alkyl, C.sub.2 -C.sub.20 -alkenyl, C.sub.2 -C.sub.20 -alkinyl, C.sub.1 -C.sub.20 -alkoxy, fluorine, chlorine, bromine, iodine, trifluoromethyl, monofluoro-C.sub.1 -C.sub.10 -alkoxy, polyfluoro-C.sub.1 -C.sub.10 -alkoxy, hydroxyl, amino, mono-C.sub.1 -C.sub.10 -alkylamino, di-C.sub.1 -C.sub.10 -alkylamino, nitro, cyano, azido, carboxyl, carb-C.sub.1 -C.sub.10 -alkoxy, carboxamido, sulphonamido, SO.sub.m -alkyl (m=0 to 2, 1 to 20 C atoms), phenyl, benzyl, benzyloxy or benzylthio, it being possible for the 4 last-mentioned substituents to carry 1 to 3 radicals from the group comprising C.sub.1 -C.sub.5 -alkyl, C.sub.1 -C.sub.5 -alkoxy, C.sub.1 -C.sub.5 -alkylthio, fluorine, chlorine, bromine, iodine, cyano, nitro, azido, hydroxyl, trifluoromethyl, amino, C.sub.1 -C.sub.6 -alkylamino or di-C.sub.1 -C.sub.6 -alkylamino,R.sup.1 represents a straight-chain, branched or cyclic saturated or unsaturated hydrocarbon radical which has 1-20 C atoms, may be interrupted in the chain by 1 or 2 oxygen or sulphur atoms and may be optionally substituted by one or more fluorine atoms, NO.sub.2, C.sub.3 -C.sub.12 -trialkyl-silyl, hydroxyl, chlorine, bromine, iodine or cyano,R.sup.2 represents hydrogen, --NH.sub.2, --CHO, cyano, --CH.sub.2 OH or a straight-chain or branched saturated or unsaturated hydrocarbon radical having 1 to 8 C atoms,R.sup.3 represents hydrogen or a straight-chain or branched C.sub.1 -C.sub.10 -alkyl radical which may be interrupted in the alkyl chain by one or two oxygen atoms and may be optionally substituted by fluorine, chlorine, bromine, iodine, --CN, --NH.sub.2, --OH or morpholino, which can be used as cardiotonics for improving the contractility of the heart. Moveover, they increase the flow of Ca.sup.++ into the cells and can therefore be employed as antihypotonics, for lowering the blood sugar level, for reducing the swelling of mucous membranes and for influencing the salt balance and/or fluid balance.
