Abstract:
A solid oral unit dosage form comprising a flavanolignan co-precipitate, a wetting agent and a pharmaceutically acceptable carrier material, where said flavanolignan co-precipitate is obtained by the process of:a) providing an aqueous-alcoholic solution of a pharmaceutically acceptable carrier material and a wetting agent, suspending a flavanolignan in the aqueous-alcoholic solution to form a mixture, heating the mixture to a boiling temperature to form a clear solution; orb) suspending a flavanolignan and a wetting agent in alcohol to form a suspension, heating the suspension with stirring to a clear solution, mixing the clear solution with an aqueous solution of a pharmaceutically acceptable carrier material to form a mixture, heating the mixture with stirring to form a clear solution; andc) subsequently concentrating the clear solution obtained according to a) or b) for the formation of a co-precipitate, filtering the concentrated solution to obtain a co-precipitate and drying the co-precipitate in a vacuum.
