  • Patent number: 6299868
    Abstract: The present invention relates to a method for treating obesity, a method for reducing the absorption of dietary fat, and a method for treating hypertriglyceridemia in a patient and to particular polymers for use in the methods or in a manufacture of a medicament. The methods comprise the step of orally administering to a mammal, such as a human, a therapeutically effective amount of one or more fat-binding polymers. The administration of the fat-binding polymer of the invention facilitates the removal of fat from the body prior to digestion, with minimal side effects and low toxicity. In a preferred embodiment, the one or more fat-binding polymers are administered in combination with one or more lipase inhibitors, for example, lipstatin and tetrahydrolipstatin.
