• Portagen® - Milk protein-based powder with medium-chain Triglycerides (MCT) for children and adults

Portagen®

Milk protein-based powder with medium-chain Triglycerides (MCT) for children and adults.

Last Updated: Monday, January 23, 2017

Indication: Portagen is a nutritional powder for children and adults with defects in the intraluminal hydrolysis of fat (decreased pancreatic lipase, decreased bile salts); defective mucosal fat absorption (decreased mucosal permeability, decreased absorptive surface); and/or defective lymphatic transport of fat (ie, intestinal lymphatic obstruction).

Portagen is not recommended for use as an infant formula.

Long-Term Usage: Portagen powder is not nutritionally complete. If used long term, supplementation of essential fatty acids and ultra-trace minerals should be considered.

  • Preparation of Feedings
    • Improper hygiene, preparation, dilution, use or storage may result in severe harm. This product is not recommended for use as an infant formula. Nutritional powders are not sterile and should not be fed to premature infants or those persons who might have immune problems unless directed and supervised by a medical professional.

      Powder

      1. Wash hands thoroughly with soap and water before preparing formula.

      2. Pour desired amount of water into bottle or cup. Add powder.

      3. Cap bottle and SHAKE WELL.

      Use the following chart for correct amounts of water and powder. Use scoop in can to measure powder. Store DRY scoop in its original can.

      To Make|| Water Powder Weight
      4.5 fl oz 4 fl oz 3 packed level scoops 28.2 g
      1 qt 27 fl oz 1 ⅔ packed level household measuring cups 203 g

      || Each scoop adds about 0.2 fl oz to the amount of prepared formula.

      Failure to follow these instructions could result in severe harm. Once prepared, product can spoil quickly. Either consume immediately or cover and store in refrigerator at 35°-40°F (2°-4°C) for no longer than 24 hours. Shake well before each use. Do not use prepared product if it is unrefrigerated for more than a total of 2 hours. Do not freeze prepared product. After feeding begins, do not refrigerate the container; you must use within 1 hour or discard.

      Powder Storage (cans)

      Store cans at room temperature. After opening can, keep tightly covered, store in dry area and use contents within 1 month. Do not freeze powder, and avoid excessive heat. Use by date on bottom of can.

      CAUTION

      Portagen® should be used only under the supervision of a physician. It is not nutritionally complete.

      Persons should drink Portagen beverage slowly and start with one or two small servings per day until they become accustomed to the product, since abdominal discomfort and/or diarrhea may occur.

      WARNING: Not for parenteral (I.V.) use.

      Powdered products are not commercially sterile. Nutritional powders should not be used for immunocompromised patients unless clinically required and then under strict medical supervision of preparation and use.

  • Product Characteristics
    • Fat

      The fat content in Portagen® is 40% of total calories. The fat blend is 87% medium-chain triglycerides (MCTs) and 13% corn oil.

      Medium chain triglycerides (MCTs) can help assure that children and adults with fat malabsorption receive an adequate energy supply. MCTs are more easily and rapidly hydrolyzed and absorbed than long-chain fatty acids by persons with fat malabsorption. Corn oil provides a source of linoleic acid.

      Fatty Acid Distribution in Portagen

      Fatty Acid (Percentage of Fatty Acids)
      C6:0 0.87
      C8:0 62
      C10:0 23.3
      C12:0 0.36
      C16:0 1.63
      C18:0 0.36
      C18:1 3.3
      C18:2 7.6
      C18:3 0.22

      Protein

      Protein provides 14% of the total calories in Portagen. The protein source is sodium caseinate, a cow's milk protein.

      Carbohydrate

      Carbohydrate provides 46% of the total calories in Portagen. The carbohydrate blend is 75% corn syrup solids and 25% sugar (sucrose). Portagen is suitable for someone with lactose intolerance.

      ¶ Not suitable for persons with galactosemia.

  • Clinical Experience
    • Clinical reports indicate that with its high level of MCT oil, Portagen may be useful in the dietary management of patients with malabsorption and steatorrhea associated with gastrectomy2, intestinal resection2,3, lymphangiectasia4,5, and pancreatic insufficiency2,5. In addition, clinicians report that patients with chyluria6, chylothorax6, and congenital ß–lipoprotein deficiency7 improved with diets high in medium-chain triglycerides.
