PROCESS FOR PREPARING FLAVONE-LIGAND PREPARATIONS WITH IMPROVED RELEASE AND RESORBING CAPACITY, IN SUCH A MANNER OBTAINED AGENTS AND THEIR USE FOR PREPARING MEDICAMENTS

摘要

The following are claimed: (A) prodn. of a flavano-lignan (FL) prepn. which has improved release properties compared to pure FL, comprising: (a1) prodn. of an aq.-alcoholic soln. of carriers and wetting agents, suspending an FL in this soln., and heating the resulting mixt. to boiling temp. to give a clear soln.; or (a2) suspending an FL and a wetting agent in alcohol, warming and stirring the suspension until a clear soln. is formed, treating this soln. with an aq. soln. of carriers, and heating and stirring the resulting mixt. until a clear soln. is formed; and (b) concentrating the clear soln. resulting from steps (a1) or (a2) until a coprecipitate is formed, then filtering and drying the coprecipitate. (B) Prepn. of a medicament for prophylactic and/or therapeutic treatment of liver disorders, comprising processing an FL prepn., which is in the form of a co-ppte. of an FL and at least one carrier (such as may be prepd. as described in (A) above) to a dosage form suitable for oral admin. Pref. the carrier is a water soluble sugar deriv. such as a mono- or disaccharide and/or a cellulose deriv. (such as sodium carboxymethyl starch, hydroxyethyl starch or carboxymethylcellulose), or is a linear polymer of 1-vinyl-2-pyrrolidone (such as polyvidone) for disperse systems. The wetting agent is polysorbate (such as polysorbate 80) or a sorbitan ester of a fatty acid.
