摘要:
An inclusion complex is disclosed of N-(1-phenylethyl)-3, 3-diphenyl-propylamine or its hydrochloride complexed with a cyclodextrin as well as a process for the preparation thereof and pharmaceutical compositions containing same. The new inclusion complexes have coronary dilatory activity and have greater water soluble than simple N-(1-phenylethyl)-3, 3-diphenyl-propyl amine or the hydrochloride thereof.

This invention provides inclusion complexes of Taxol ((2aR-(a&agr;,4&bgr;,4&agr;&bgr;,6&bgr;,9&agr;(&agr;R*,&bgr;S*),11&agr;,12&agr;,12a&agr;,12b&agr;))-&bgr;-(benzoylamino)-&agr;-hydroxy-benzene-propanoic acid 6,12-b-bis(acetyloxy)-12-(benzoyloxy)-2a,3,4,4a,5,6,9,10,11,12,12a,12b-dodecahydro-4,11-dihydroxy-4a,8,13,13-tetramethyl-5-oxo-7,11-methano-1H-cyclo-deca-(3,4)-benz-(1,2-b)-oxeth-9-yl-ester)) or Taxotere (butoxycarbonyl-10-desacetyl-N-debenzoyl-Taxol) or Taxus extracts formed with a cyclodextrin derivative and a co-solvent. This invention relates to pharmaceutical composition with increased water-solubility and stability. This invention provides the process for the preparation of an inclusion complex of Taxol or Taxotere or a brevifolia extract of Taxus formed with a cyclodextrin derivative and a co-solvent. This invention relates to pharmaceutical composition, containing as active ingredient an effective amount of an inclusion complex of Taxol or Taxotere or a Taxus brevifolia extract formed with a cyclodextrin derivative, preferably heptakis-2,6-0 dimethyl-&bgr;-cyclodextrin, random methylated &bgr;-cyclodextrin, succinylmethyl-&bgr;-cyclodextrin and a co-solvent together with usual filling, diluting and other auxiliaries generally used in the pharmaceutical industry.
