Abstract: Compositions and methods for reducing the body weight of a mammal are disclosed. The invention is directed to methods for reducing the body weight in a mammal comprising administering therapeutically effective amounts of a fatty-acid ester of an estrogen or estrogen derivative and a fatty-acid, and a thermogenic compound. Furthermore the invention is directed to compositions comprising a fatty-acid ester of an estrogen or estrogen derivative and a fatty-acid, and a thermogenic compound.

Abstract: The pharmaceutical and/or cosmetic compositions for treatment of obesity and/or overweight contain an effective amount of a fatty-acid monoester of an estrogen and a fatty acid wherein the estrogen is estrone, diethylstilbestrol, estriol, estradiol or ethinyl estradiol and the fatty acid is oleic, linoleic, linolenic, stearic, palmitic, palmitoleic or arachidonic acids. The fatty-acid monoesters mimic the function of estrone monooleate, as a signal that informs the brain of the size of fat tissue mass. In preferred pharmaceutical and/or cosmetic compositions for intravenous injection the monoester is incorporated in a lipidic suspension, prepared from lipoproteins or from liposome components, such as soy oil and egg phospholipids. When administered to rats with a 15% of total adipose tissue, they produce weight reduction of about 10%, by a new and unexpected mechanism. They are useful for the treatment of obesity and/or overweight in mammals, with the advantages of high efficacy and low toxicity.
