  • Certain biphenyl derivatives used to treat disorders caused by increased capillary permeability
    Patent number: 4015017
    Abstract: Pharmaceutical compositions the essential active ingredient of which is a biphenyl derivative, at least one of the phenyl nuclei of which has two adjacent hydroxyl groups, the two phenyl nuclei being separated by a carbon chain having one or two carbon atoms and in general, a double bend between two chain carbon atoms or between a chain carbon atom and a substituent thereof. The compositions are useful for the treatment of disorders of the blood micro-circulation.
