  • Patent number: 5534505
    Abstract: The active agent ursodeoxycholic acid has proved therapeutically active in infants, inter alia for the treatment of cholestatic hepatic diseases. A problem when administering this active agent, a bile acid, to infants is its extreme bitterness. As a result of the present invention a taste-acceptable, liquid administration form for ursodeoxycholic acid with an adequately high active agent concentration is described. The liquid to be ingested is a suspension prepared accompanied by the addition of a swelling and/or thickening agent, which contains the active agent mainly in fine crystalline form as the disperse phase and only in a much smaller proportion dissolved in the aqueous dispersant. A remaining residual bitterness can be additionally masked by the addition of .beta.-cyclodextrin or suitable taste correcting agents.
