ABSTRACT:
The invention relates to tetrazole derivatives of bile acids, processes for their preparation, and use of these compounds as medicaments and cholesterol lowering agents. The tetrazole-bile acid derivatives are of the formula G1--X--G2, where G1 is H, a bile acid radical, or a bile acid radical which is modified on the hydroxyl functions and/or on the carboxyl group, X is a single bond or a bridge group between G1 and G2, and G2 is of the formula: ##STR1##
