  • Patent number: 8828412
    Abstract: Disclosed herein are stable oil-in-water emulsion ophthalmic topical liquid compositions having an average particle size less than 1 ?m including at least one plant-derived oil other than castor oil wherein the oil comprises only aliphatic side chains free of polar pendent groups. The oil-in-water emulsion ophthalmic topical liquid compositions also include a hydrophilic surfactant having an HLB value between approximately 10 and 14, a vegetable oil-derived hydrophobic non-co-block surfactant having unsaturated side chains that contain less than four oxygen atoms having an HLB value between approximately 4 and 6 and is a liquid at room temperature. The oil-in-water emulsion ophthalmic topical liquid compositions disclosed herein can further include an amount of cyclosporine A or polyphenol in an amount effective to relieve dry eye symptoms.

  • Publication number: 20040219188
    Abstract: This invention relates to compositions and methods for nutritional management of hepatic (liver) failure. In particular the invention is directed to a nutritionally complete formulation suitable for use as a supplement or total enteral feeding. The composition is specifically tailored to meet the requirements of hepatic patients in need of nutritional support. The composition comprises an organoleptically acceptable protein system designed to meet the altered metabolic needs of patients suffering from hepatic failure. The invention also relates to administering a nutritional composition comprising effective amounts of the branched-chain amino acids, valine, leucine, isoleucine, or mixtures thereof, and with or without a reduced amount of tyrosine, phenylalanine and tryptophan.

  • Patent number: 6444700
    Abstract: In its broadest aspect, the present invention is directed to the discovery of immunonutritional products that are useful in reducing the immunological system suppression that results from stress. The stress may be in the form of physical exertion, mental exhaustion, disease states and the like. In one embodiment, the invention relates to a nutritional composition comprising a structured glyceride component and an antioxidant system. This nutritional composition has been shown to be highly effective in reducing immune system down regulation or dysregulation as a result of stress.

  • Patent number: 6440470
    Abstract: The present invention is directed to an elemental liquid nutritional product useful for providing nutrition to a patient having a malabsorption condition by enterally feeding to the patient a nutritionally effective amount of the liquid nutritional products of the present invention. One nutritional product of the present invention includes a protein system in which at least 65 w/w % of said proteins have a molecular weight of less than 5,000 daltons. The proteins system includes soy protein hydrolysate, and partially hydrolyzed caseinate. The preferred products further include a structured lipid formed from marine oil and medium chain triglyceride oil. Palatability of elemental nutritional products has been improved by keeping caloric density in a range from 0.60 kcal/ml to about 1.05 kcal/ml and incorporating sufficient amounts of selected palatability enhancers.
