  • Patent number: 5519012
    Abstract: Novel inclusion complexes of racemic 1,4-dihydropyridines and enantiomers thereof of the formula ##STR1## wherein R represents a phenyl group, substituted with nitro, trifluoromethyl, difluoromethoxy group or with one or two halo atoms (especially chlorine),R.sub.1 and R.sub.2, if the same, represent methyl groups and if one of them has the meaning of a 2-aminoethoxymethyl or cyano group, the other represents a methyl group,R.sub.3 and R.sub.4, if different, stand each time for a hydrogen, linear or branched C.sub.1 -C.sub.6 -alkyl, 2-methoxyethyl, 1-(phenylmethyl)-3-piperidinylphenyl, styryl, furyl, piperidino, 4-diphenylmethyl-1-piperazinylethyl, 5-phenyl-3-pirazolyloxy, 1-phenyl-methyl-3-pyrrolidinyl group or a group of the formula ##STR2## or, if the same, stand each time C.sub.1 -C.sub.4 alkyl group, and of acid addition salts thereof with methyl-.beta.-cyclodextrin, hydroxy-ethyl-.beta.-cyclodextrin or hydroxypropyl-.beta.

  • Patent number: 5079237
    Abstract: There is described a new inclusion complex of nicardipine or its hydrochloride with beta-cyclohdextrin, which is prepared by admixing nicardipine or its hydrochloride with beta-cyclodextrin in a molar ratio of the compounds 1:0.9-1.1 under stirring at a temperature from about room temperature to the boiling temperature of the reaction mixture in an aqueous or ethanolic medium, cooling the reaction mixture to 0.degree. to 5.degree. C. and isolating the desired complex.The inclusion complex of nicardipine or its hydrochloride posesses cerebrovascular-vasodilatory and coronary-vasodilatory properties, which are equally well expressed as those of nicardipine or its hydrochloride themselves, yet owing to the better solubility of the complex at a higher pH range, such as it exists e.g. in the intestinal tract, the manufacture of sustained release pharmaceutical forms is made possible, whereby a greater extent of dissolution of the active substance is provided also in the intestinal juice.
