  The appropriate daily dose of amino acids to be used with dextrose or with dextrose and intravenous fat emulsion will depend upon the metabolic status and clinical response of the patient as therapy proceeds. Doses which achieve nitrogen equilibrium or positive balance are the most desirable. The dosage on the first day should be approximately half the anticipated optimal dosage and should be increased gradually to minimize glycosuria; similarly, withdrawal should be accomplished gradually to avoid rebound hypoglycemia.

  Fat emulsion coadministration should be considered when prolonged (more than 5 days) parenteral nutrition is required in order to prevent essential fatty acid deficiency (EFAD). Serum lipids should be monitored for evidence of EFAD in patients maintained on fat free TPN.

  The amount administered is dosed on the basis of amino acids/kg of body weight/day. In general, two to three g/kg of body weight for neonates and infants with adequate calories are sufficient to satisfy protein needs and promote positive nitrogen balance. In pediatric patients, the final solution should not exceed twice normal serum osmolarity (718 mOsmol/L).

  DIRECTIONS FOR PROPER USE OF PHARMACY BULK PACKAGE

  Plenamine™ 15% in a Pharmacy Bulk Package is not intended for direct infusion. The container closure may be penetrated only once using a suitable sterile transfer device or dispensing set which allows measured dispensing of the contents. The Pharmacy Bulk Package is to be used only in a suitable work area such as a laminar flow hood (or an equivalent clean air compounding area). Once the closure is penetrated, the contents should be dispensed as soon as possible; the transfer of contents must be completed within 4 hours of closure entry. The bottle may be stored at room temperature (25°C) after the closure has been entered. Date and time of container entry should be noted in the area designated on the container label.

  When using Plenamine™ 15% in patients with a need for fluid volume restriction, it can be diluted as follows:

  Volume Amount Final Concentration Plenamine™ 15% 500 mL 75 g 7.5% Dextrose 70% 250 mL 175 g 17.5% Intralipid® 20% 250 mL 50 g 5.0%

  This will provide 1395 kilocalories (kcal) per 1000 mL of admixture with a ratio of 118 non-protein calories per gram of nitrogen and an osmolarity of 1561 mOsmol/L.

  In patients where the need for fluid restriction is not so marked, either of the following regimens may be used dependent upon the energy needs of the patient.

  Volume Amount Final Concentration Plenamine™ 15% 500 mL 75 g 3.75% Dextrose 50% 1000 mL 500 g 25% Intralipid® 20% 500 mL 100 g 5%

  This will provide 1500 kcal per 1000 mL of admixture with a ratio of 228 non-protein calories per gram of nitrogen and an osmolarity of 1633 mOsmol/L.

  Volume Amount Final Concentration Plenamine™ 15% 500 mL 75 g 3.75% Dextrose 30% 1000 mL 300 g 15% Intralipid® 10% 500 mL 50 g 2.5%

  This will provide 935 kcal per 1000 mL of admixture with a ratio of 158 non-protein calories per gram of nitrogen and an osmolarity of 1128.5 mOsmol/L.

  A. Total Parenteral Nutrition (Central Infusion)

  不重读的成人患者没有不寻常的硝基gen losses, a minimum dosage of 0.1 gram nitrogen (4.2 mL of Plenamine™ 15%) plus 4.4 grams (15 calories) of dextrose per kilogram of body weight per day are required to achieve nitrogen balance and weight stability. Intravenous fat emulsion may be used as a partial substitute for dextrose. This regimen provides a ratio of 150 non-protein calories per gram of nitrogen.

  For patients stressed by surgery, trauma or sepsis, and those with unusual nitrogen losses, the dosage required for maintenance may be as high as 0.3 to 0.4 grams of nitrogen (13 to 17 mL Plenamine™ 15%) per kilogram of body weight per day, with proportionate increases in non-protein calories. Periodic assessment of nitrogen balance of the individual patient is the best indicator of proper dosage. Volume overload and glycosuria may be encountered at high dosage, and nitrogen balance may not be achieved in extremely hypermetabolic patients under these constraints. Concomitant insulin administration may be required to minimize glycosuria. Daily laboratory monitoring is essential.

  Use of an infusion pump is advisable to maintain a steady infusion rate during central venous infusion.

  B. Peripheral Nutrition

  In patients for whom central venous catheterization is not advisable, protein catabolism can be reduced by peripheral use of diluted Plenamine™ 15% plus non-protein calorie sources. Dilution of 250 mL Plenamine™ 15% in 750 mL of 10% dextrose will reduce the osmolarity to a level (724 mOsmol/L) which is more favorable to the maintenance of the integrity of the walls of the veins. Intravenous fat emulsion can be infused separately or simultaneously; if infused simultaneously the fat emulsion will provide a dilution effect upon the osmolarity while increasing the energy supply.

  Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

  To reduce the risk of bacterial contamination, all intravenous administration sets should be replaced at least every 24 hours. Usage of admixtures must be initiated within 24 hours after mixing. If storage is necessary during this 24 hour period, admixtures must be refrigerated and completely used within 24 hours of beginning administration.
