  • Patent number: 5668126
    Abstract: Bile acid derivatives of the formula IW--X--Gin which G is a bile acid radical, W is an active compound moiety of a medicament and X is a bonding member between a bile acid radical and active compound moiety, are outstandingly suitable for introducing active compounds into the enterohepatic circulation. The compounds I are absorbed and pass into the bloodstream. It is possible in this way, using the natural reabsorption of the bile acids, to achieve improved absorption of non-absorbable or poorly absorbable pharmaceuticals.W may be, for example, a peptide, an antibiotic, an antiviral substance, an anticancer agent, a hepatoprotective agent, an antihyperlipidemic, a diuretic, a hypotensive, a renin inhibitor, a substance for the treatment of cirrhosis of the liver or a substance for the treatment of diabetes.G is a bile acid radical in the form of the free natural or chemically modified acids, the esters and amides, the salt forms and forms derivatized on alcohol groups.
