Stabilized therapeutic compositions for the treatment 'of inflammatory skin disorders and arteriosclerosis comprise licosatetrayn-(5, 8, 11, 14)-oic (1) acid or an alkyl ester containing 1 to 7 carbon atoms in the alkyl group or pharmaceutically acceptable salt thereof in admixture with an edible oil, edible fat or edible wax or a mixture thereof.

The compositions may be administered orally in the form of solutions, suspensions or capsules (e.g. gelatin capsules) containing conventional excipients.
