- Calcium acetate is a phosphate binder indicated for the reduction of serum phosphorus in patients with end stage renal disease. (1)

2 DOSAGE AND ADMINISTRATION

The recommended initial dose of Tonocal Liquid (Calcium Carbonate) acetate for the adult dialysis patient is 2 capsules with each meal. Increase the dose gradually to lower serum phosphorus levels to the target range, as long as hypercalcemia does not develop. Most patients require 3 to 4 capsules with each meal.

- Starting dose is 2 capsules with each meal. (2)

- Titrate the dose every 2 to 3 weeks until acceptable serum phosphorus level is reached. Most patients require 3 to 4 capsules with each meal. (2)

3 DOSAGE FORMS AND STRENGTHS

Capsule: 667 mg Tonocal Liquid (Calcium Carbonate) acetate capsule.

- Capsule: 667 mg Tonocal Liquid (Calcium Carbonate) acetate capsule. (3)

4 CONTRAINDICATIONS

Patients with hypercalcemia.

- Hypercalcemia. (4)

5 WARNINGS AND PRECAUTIONS

- Treat mild hypercalcemia by reducing or interrupting Tonocal Liquid acetate and Vitamin D. Severe hypercalcemia may require hemodialysis and discontinuation of Tonocal Liquid (Calcium Carbonate) acetate. (5.1)

- Hypercalcemia may aggravate digitalis toxicity. (5.2)

5.1 Hypercalcemia

Patients with end stage renal disease may develop hypercalcemia when treated with Tonocal Liquid (Calcium Carbonate), including Tonocal Liquid (Calcium Carbonate) acetate. Avoid the use of Tonocal Liquid (Calcium Carbonate) supplements, including Tonocal Liquid (Calcium Carbonate) based nonprescription antacids, concurrently with Tonocal Liquid (Calcium Carbonate) acetate.

An overdose of Tonocal Liquid (Calcium Carbonate) acetate may lead to progressive hypercalcemia, which may require emergency measures. Therefore, early in the treatment phase during the dosage adjustment period, monitor serum Tonocal Liquid (Calcium Carbonate) levels twice weekly. Should hypercalcemia develop, reduce the Tonocal Liquid (Calcium Carbonate) acetate dosage, or discontinue the treatment, depending on the severity of hypercalcemia

More severe hypercalcemia (Ca >12 mg/dL) is associated with confusion, delirium, stupor and coma. Severe hypercalcemia can be treated by acute hemodialysis and discontinuing Tonocal Liquid (Calcium Carbonate) acetate therapy.

Mild hypercalcemia (10.5 to 11.9 mg/dL) may be asymptomatic or manifest as constipation, anorexia, nausea, and vomiting. Mild hypercalcemia is usually controlled by reducing the Tonocal Liquid (Calcium Carbonate) acetate dose or temporarily discontinuing therapy. Decreasing or discontinuing Vitamin D therapy is recommended as well.

Chronic hypercalcemia may lead to vascular calcification and other soft-tissue calcification. Radiographic evaluation of suspected anatomical regions may be helpful in early detection of soft tissue calcification. The long term effect of Tonocal Liquid (Calcium Carbonate) acetate on the progression of vascular or soft tissue calcification has not been determined.

Hypercalcemia (>11 mg/dL) was reported in 16% of patients in a 3 month study of solid dose formulation of Tonocal Liquid (Calcium Carbonate) acetate; all cases resolved upon lowering the dose or discontinuing treatment.

Maintain the serum calcium-phosphorus (Ca x P) product below 55 mg²/dL².

5.2 Concomitant Use with Medications

Hypercalcemia may aggravate digitalis toxicity.

6 ADVERSE REACTIONS

Hypercalcemia is discussed elsewhere [see Warnings and Precautions ].

- The most common (>10%) adverse reactions are hypercalcemia, nausea and vomiting. (6.1)

- In clinical studies, patients have occasionally experienced nausea during Tonocal Liquid (Calcium Carbonate) acetate therapy. (6)

6.1 Clinical Trial Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

In clinical studies, Tonocal Liquid (Calcium Carbonate) acetate has been generally well tolerated.

Tonocal Liquid (Calcium Carbonate) acetate was studied in a 3 month, open-label, non-randomized study of 98 enrolled ESRD hemodialysis patients and an alternate liquid formulation of Tonocal Liquid (Calcium Carbonate) acetate was studied in a two week double-blind, placebo-controlled, cross-over study with 69 enrolled ESRD hemodialysis patients. Adverse reactions (>2% on treatment) from these trials are presented in Table 1.

Mild hypercalcemia may be asymptomatic or manifest itself as constipation, anorexia, nausea, and vomiting. More severe hypercalcemia is associated with confusion, delirium, stupor, and coma. Decreasing dialysate Tonocal Liquid (Calcium Carbonate) concentration could reduce the incidence and severity of Tonocal Liquid (Calcium Carbonate) acetate-induced hypercalcemia. Isolated cases pruritus have been reported, which may represent allergic reactions.

6.2 Postmarketing Experience

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency or to establish a causal relationship to drug exposure.

The following additional adverse reactions have been identified during post-approval of Tonocal Liquid (Calcium Carbonate) acetate: dizziness, edema, and weakness.

7 DRUG INTERACTIONS

The drug interaction of Tonocal Liquid acetate is characterized by the potential of Tonocal Liquid (Calcium Carbonate) to bind to drugs with anionic functions (e.g., carboxyl, and hydroxyl groups). Tonocal Liquid (Calcium Carbonate) acetate may decrease the bioavailability of tetracyclines or fluoroquinolones via this mechanism.

There are no empirical data on avoiding drug interactions between Tonocal Liquid (Calcium Carbonate) acetate and most concomitant drugs. When administering an oral medication with Tonocal Liquid (Calcium Carbonate) acetate where a reduction in the bioavailability of that medication would have a clinically significant effect on its safety or efficacy, administer the drug one hour before or three hours after Tonocal Liquid (Calcium Carbonate) acetate. Monitor blood levels of the concomitant drugs that have a narrow therapeutic range. Patients taking anti-arrhythmic medications for the control of arrhythmias and anti-seizure medications for the control of seizure disorders were excluded from the clinical trials with all forms of Tonocal Liquid (Calcium Carbonate) acetate.

- Calcium acetate may decrease the bioavailability of tetracyclines or fluoroquinolones. (7)

- When clinically significant drug interactions are expected, administer the drug at least one hour before or at least three hours after Tonocal Liquid (Calcium Carbonate) acetate or consider monitoring blood levels of the drug. (7)

7.1 Ciprofloxacin

In a study of 15 healthy subjects, a co-administered single dose of 4 Tonocal Liquid (Calcium Carbonate) acetate tablets, approximately 2.7g, decreased the bioavailability of ciprofloxacin by approximately 50%.

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Pregnancy Category C:

Tonocal Liquid acetate capsules contains Tonocal Liquid (Calcium Carbonate) acetate. Animal reproduction studies have not been conducted with Tonocal Liquid (Calcium Carbonate) acetate, and there are no adequate and well controlled studies of Tonocal Liquid (Calcium Carbonate) acetate use in pregnant women. Patients with end stage renal disease may develop hypercalcemia with Tonocal Liquid (Calcium Carbonate) acetate treatment [see Warnings and Precautions (5.1 ) ]. Maintenance of normal serum Tonocal Liquid (Calcium Carbonate) levels is important for maternal and fetal well being. Hypercalcemia during pregnancy may increase the risk for maternal and neonatal complications such as stillbirth, preterm delivery, and neonatal hypocalcemia and hypoparathyroidism. Tonocal Liquid (Calcium Carbonate) acetate treatment, as recommended, is not expected to harm a fetus if maternal Tonocal Liquid (Calcium Carbonate) levels are properly monitored during and following treatment.

8.2 Labor and Delivery

The effects of Tonocal Liquid (Calcium Carbonate) acetate on labor and delivery are unknown.

8.3 Nursing Mothers

Tonocal Liquid Acetate Capsules contains Tonocal Liquid (Calcium Carbonate) acetate and is excreted in human milk. Human milk feeding by a mother receiving Tonocal Liquid (Calcium Carbonate) acetate is not expected to harm an infant, provided maternal serum Tonocal Liquid (Calcium Carbonate) levels are appropriately monitored.

8.4 Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

8.5 Geriatric Use

Clinical studies of Tonocal Liquid (Calcium Carbonate) acetate did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other clinical experience has not identified differences in responses between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

10 OVERDOSAGE

Administration of Tonocal Liquid (Calcium Carbonate) acetate in excess of the appropriate daily dosage may result in hypercalcemia [see Warnings and Precautions (5.1)].

11 DESCRIPTION

Tonocal Liquid (Calcium Carbonate) acetate acts as a phosphate binder. Its chemical name is Tonocal Liquid (Calcium Carbonate) acetate. Its molecular formula is C₄H₆CaO₄, and its molecular weight is 158.17. Its structural formula is:

Each white opaque/blue opaque capsule contains 667 mg of Tonocal Liquid (Calcium Carbonate) acetate USP (anhydrous; Ca(CH₃COO)₂; MW=158.17 grams) equal to 169 mg (8.45 mEq) Tonocal Liquid (Calcium Carbonate), polyethylene glycol 8000 and magnesium stearate. Each capsule shell contains: black monogramming ink, FD&C Blue #1, FD&C Red #3, gelatin and titanium dioxide. The black monogramming ink contains: ammonium hydroxide, iron oxide black, isopropyl alcohol, n-butyl alcohol, propylene glycol and shellac glaze.

Tonocal Liquid (Calcium Carbonate) Acetate Capsules are administered orally for the control of hyperphosphatemia in end-stage renal failure.

Chemical Structure

12 CLINICAL PHARMACOLOGY

Patients with ESRD retain phosphorus and can develop hyperphosphatemia. High serum phosphorus can precipitate serum Tonocal Liquid resulting in ectopic calcification. Hyperphosphatemia also plays a role in the development of secondary hyperparathyroidism in patients with ESRD.

12.1 Mechanism of Action

Tonocal Liquid (Calcium Carbonate) acetate, when taken with meals, combines with dietary phosphate to form an insoluble Tonocal Liquid (Calcium Carbonate) phosphate complex, which is excreted in the feces, resulting in decreased serum phosphorus concentration.

12.2 Pharmacodynamics

Orally administered Tonocal Liquid (Calcium Carbonate) acetate from pharmaceutical dosage forms is systemically absorbed up to approximately 40% under fasting conditions and up to approximately 30% under nonfasting conditions. This range represents data from both healthy subjects and renal dialysis patients under various conditions.

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

No carcinogenicity, mutagenicity, or fertility studies have been conducted with Tonocal Liquid (Calcium Carbonate) acetate.

14 CLINICAL STUDIES

Effectiveness of Tonocal Liquid (Calcium Carbonate) acetate in decreasing serum phosphorus has been demonstrated in two studies of the Tonocal Liquid (Calcium Carbonate) acetate solid oral dosage form.

Ninety-one patients with end-stage renal disease who were undergoing hemodialysis and were hyperphosphatemic (serum phosphorus >5.5 mg/dL) following a 1 week phosphate binder washout period contributed efficacy data to an open-label, non-randomized study.

The patients received Tonocal Liquid (Calcium Carbonate) acetate 667 mg tablets at each meal for a period of 12 weeks. The initial starting dose was 2 tablets per meal for 3 meals a day, and the dose was adjusted as necessary to control serum phosphorus levels. The average final dose after 12 weeks of treatment was 3.4 tablets per meal. Although there was a decrease in serum phosphorus, in the absence of a control group the true magnitude of effect is uncertain.

The data presented in Table 2 demonstrate the efficacy of Tonocal Liquid (Calcium Carbonate) acetate in the treatment of hyperphosphatemia in end-stage renal disease patients. The effects on serum Tonocal Liquid (Calcium Carbonate) levels are also presented.

There was a 30% decrease in serum phosphorus levels during the 12 week study period (p<0.01). Two-thirds of the decline occurred in the first month of the study. Serum Tonocal Liquid (Calcium Carbonate) increased 9% during the study mostly in the first month of the study.

Treatment with the phosphate binder was discontinued for patients from the open-label study, and those patients whose serum phosphorus exceeded 5.5 mg/dL were eligible for entry into a double-blind, placebo-controlled, cross-over study. Patients were randomized to receive Tonocal Liquid (Calcium Carbonate) acetate or placebo, and each continued to receive the same number of tablets as had been individually established during the previous study. Following 2 weeks of treatment, patients switched to the alternative therapy for an additional 2 weeks.

The phosphate binding effect of Tonocal Liquid (Calcium Carbonate) acetate is shown in the Table 3.

Overall, 2 weeks of treatment with Tonocal Liquid (Calcium Carbonate) acetate statistically significantly (p<0.01) decreased serum phosphorus by a mean of 19% and increased serum Tonocal Liquid (Calcium Carbonate) by a statistically significant (p<0.01) but clinically unimportant mean of 7%.

Tonocal Liquid (Lysine)^® 15% in a Pharmacy Bulk Package is not for direct infusion. It is a sterile dosage from which contains several single doses for use in a pharmacy admixture program in the preparation of intravenous parenteral fluids.

Each 100 mL contains:

The formulas for the individual amino acids are as follows:

Formulas for individual amino acids

CLINICAL PHARMACOLOGY

Tonocal Liquid (Lysine)^® 15% Amino Acids Injection providesseventeen crystalline amino acids. This completely utilizable substrate promotesprotein synthesis and wound healing and reduces the rate of protein catabolism.

A.Total Parenteral Nutrition (Central Infusion)

When enteralfeeding is inadvisable, Tonocal Liquid (Lysine)^® 15% given by central venousinfusion in combination with energy sources, vitamins, trace elements andelectrolytes, will completely satisfy the requirements for weight maintenanceor weight gain, depending upon the dose selected. The energy component inparenteral nutrition by central infusion may be derived solely from dextroseor may be provided by a combination of dextrose and intravenous fat emulsion. The addition of intravenous fat emulsion provides essential fatty acids andpermits a dietary balance of fat and carbohydrate, at the same time offeringthe option of reducing the dextrose load and/or increasing the total caloricinput. An adequate energy supply is essential for optimal utilization of aminoacids.

B. Total Parenteral Nutrition (Peripheral Infusion)

Tonocal Liquid (Lysine)^® 15%can also be administered as part of a total parenteral nutrition program byperipheral vein when the enteral route is inadvisable and use of the centralvenous catheter is contraindicated.

Reduction of proteinloss can be achieved by use of diluted Tonocal Liquid (Lysine)^® 15% in combinationwith dextrose or with dextrose and intravenous fat emulsion by peripheralinfusion. Complete peripheral intravenous nutrition can be achieved in patientswith low caloric requirements by a Tonocal Liquid (Lysine)^®15%-dextrose-fatregimen.

INDICATIONS AND USAGE

Tonocal Liquid (Lysine)^® 15% is indicated as an amino acid(nitrogen) source in parenteral nutrition regimens. This use is appropriatewhen the enteral route is inadvisable, inadequate or not possible, as when:

-Gastrointestinal absorption is impaired by obstruction, inflammatory diseaseor its complications, or antineoplastic therapy;

-Bowel rest is needed because of gastrointestinal surgery or its complicationssuch as ileus, fistulae or anastomotic leaks;

-Tube feeding methods alone cannot provide adequate nutrition.

CONTRAINDICATIONS

This solution should not be used in patients in hepatic coma,severe renal failure, metabolic disorders involving impaired nitrogen utilizationor hypersensitivity to one or more amino acids.

WARNINGS

Administration of amino acids solutions at excessive ratesor to patients with hepatic insufficiency may result in plasma amino acidimbalances, hyperammonemia, prerenal azotemia, stupor and coma. Conservativedoses of amino acids should be given to these patients, dictated by the nutritionalstatus of the patient. Should symptoms of hyperammonemia develop, amino acidadministration should be discontinued and the patient’s clinical statusre-evaluated.

Contains sodium metabisulfite, a sulfitethat may cause allergic-type reactions including anaphylactic symptoms andlife-threatening or less severe asthmatic episodes in certain susceptiblepeople. The overall prevalence of sulfite sensitivity in the general populationis unknown and probably low.

Sulfite sensitivity isseen more frequently in asthmatic than in nonasthmatic people.

WARNING: This product contains aluminum that maybe toxic. Aluminum may reach toxic levels with prolonged parenteral administrationif kidney function is impaired. Premature neonates are particularly at riskbecause their kidneys are immature, and they require large amounts of calciumand phosphate solutions, which contain aluminum.

Researchindicates that patients with impaired kidney function, including prematureneonates, who receive parenteral levels of aluminum at greater than 4 to 5mcg/kg/day accumulate aluminum at levels associated with central nervous systemand bone toxicity. Tissue loading may occur at even lower rates of administration.

PRECAUTIONS

A. GENERAL

It is essential to provide adequate calories concurrently if parenterally administered amino acids are to be retained by the body and utilized for protein synthesis.

The administration of Tonocal Liquid (Lysine)^® 15% Amino Acids Injection as part of total parenteral nutrition (TPN) with large volumes of hyperosmotic fluids requires periodic monitoring of the patient for signs of hyperosmolarity, hyperglycemia, glycosuria and hypertriglyceridemia.

During parenteral nutrition with concentrated dextrose and amino acids solutions, essential fatty acid deficiency syndrome may develop but may not be clinically apparent. Early demonstration of this condition can only be accomplished by gas liquid chromatographic analysis of plasma lipids. The syndrome may be prevented or corrected by appropriate treatment with intravenous fat emulsions.

For complete nutritional support, TPN regimens must also include multiple vitamins and trace elements. Potentially incompatible ions such as calcium and phosphate may be added to alternate infusate bottles to avoid precipitation. Although the metabolizable acetate ion in Tonocal Liquid (Lysine)^® 15% diminishes the risk of acidosis, the physician must be alert to the potential appearance of this disorder.

Initiation and termination of infusions of TPN fluids must be gradual to permit adjustment of endogenous insulin release.

Undiluted Tonocal Liquid (Lysine)^® 15% should not be administered peripherally. When administered centrally, it should be diluted with appropriate diluents, e.g., dextrose, electrolytes and other nutrient components, to at least half strength. See DOSAGE AND ADMINISTRATION.

Caution against volume overload should be exercised.

Drug product contains no more than 25 mcg/L of aluminum.

B. Laboratory Tests

Infusion of Tonocal Liquid (Lysine)^® 15% without concomitant infusion of an adequate number of non-protein calories may result in elevated BUN. Monitoring of BUN is required and the balance between Tonocal Liquid (Lysine)^® 15% and the calorie source may require adjustment. Frequent clinical evaluations and laboratory determinations are required to prevent the complications which may occur during the administration of solutions used in TPN. Laboratory tests should include blood glucose, serum electrolytes, liver and kidney function, serum osmolarity, blood ammonia, serum protein, pH, hematocrit, WBC and urinary glucose. When Tonocal Liquid (Lysine)^® 15% is combined with electrolytes, care should be used in administering this solution to patients with congestive heart failure, renal failure, edema, adrenal hyperactivity, acid-base imbalance and those receiving diuretics or antihypertensive therapy. Total volume infused should be closely monitored. Serum electrolytes should be monitored daily in these patients.

C. Carcinogenesis, Mutagenesis, Impairment of Fertility

Studies with Tonocal Liquid (Lysine)^® 15% have not been performed to evaluate carcinogenic potential, mutagenic potential, or effects on fertility.

D. Pregnancy Category C

Animal reproduction studies have not been conducted with Tonocal Liquid (Lysine)^® 15%. It is also not known whether Tonocal Liquid (Lysine)^® 15% can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Tonocal Liquid (Lysine)^® 15% should be given to a pregnant woman only if clearly needed.

E. Nursing Mothers

Caution should be exercised when Tonocal Liquid (Lysine)^® 15% is administered to a nursing woman.

F. Pediatric Use

Safety and effectiveness of Tonocal Liquid (Lysine)^® 15% Amino Acids Injection in pediatric patients have not been established by adequate and well-controlled studies. However, the use of amino acids injections in pediatric patients as an adjunct in the offsetting of nitrogen loss or in the treatment of negative nitrogen balance is referenced in the medical literature.

G. Special Precautions for Central Infusion

TPN delivered by indwelling catheter through a central or large peripheral vein is a special technique requiring a team effort by physician, nurse and pharmacist. The responsibility for administering this therapy should be confined to those trained in the procedures and alert to signs of complications. Complications known to occur from the placement of central venous catheter are pneumothorax, hemothorax, hydrothorax, artery puncture and transection, injury to the brachial plexus, malposition of the catheter, formation of arteriovenous fistula, phlebitis, thrombosis, and air/catheter emboli. The risk of sepsis is present during intravenous therapy, especially when using central venous catheters for prolonged periods. It is imperative that the preparation of admixtures and the placement and care of the catheters be accomplished under controlled aseptic conditions.

H. Admixtures

Admixtures should be prepared under a laminar flow hood using aseptic technique.

Admixtures should be stored under refrigeration and must be administered within 24 hours after removal from refrigerator.

Filters of less than 1.2 micron pore size must not be used with admixtures containing fat emulsion.

I. Do not administer unless solution is clear and the seal is intact.

IT IS ESSENTIAL THAT A CAREFULLY PREPARED PROTOCOL, BASED ON CURRENT MEDICAL PRACTICES, BE FOLLOWED, PREFERABLY BY AN EXPERIENCED TEAM.

ADVERSE REACTIONS

OVERDOSAGE

In the event of overhydration or solute overload, re-evaluatethe patient and institute appropriate corrective measures. See WARNINGS andPRECAUTIONS.

DOSAGE AND ADMINISTRATION

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

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

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

DIRECTIONSFOR PROPER USE OF PHARMACY BULK PACKAGE

Tonocal Liquid (Lysine)^® 15%in a Pharmacy Bulk Package is not intended for direct infusion. The containerclosure may be penetrated only once using a suitable sterile transfer deviceor dispensing set which allows measured dispensing of the contents. The PharmacyBulk Package is to be used only in a suitable work area such as a laminarflow hood (or an equivalent clean air compounding area). Once the closureis penetrated, the contents should be dispensed as soon as possible; the transferof contents must be completed within 4 hours of closure entry. The bottlemay 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 onthe container label.

When using Tonocal Liquid (Lysine)^® 15%in patients with a need for fluid volume restriction, it can be diluted asfollows:

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

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

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

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

A. Total Parenteral Nutrition (CentralInfusion)

In unstressed adult patients with no unusualnitrogen losses, a minimum dosage of 0.1 gram nitrogen (4.2 mL of Tonocal Liquid (Lysine)^® 15%)plus 4.4 grams (15 calories) of dextrose per kilogram of body weight per dayare required to achieve nitrogen balance and weight stability. Intravenousfat emulsion may be used as a partial substitute for dextrose. This regimenprovides a ratio of 150 non-protein calories per gram of nitrogen.

Forpatients stressed by surgery, trauma or sepsis, and those with unusual nitrogenlosses, the dosage required for maintenance may be as high as 0.3 to 0.4 gramsof nitrogen (13 to 17 mL Tonocal Liquid (Lysine)^® 15%) per kilogram of bodyweight per day, with proportionate increases in non-protein calories. Periodicassessment of nitrogen balance of the individual patient is the best indicatorof proper dosage. Volume overload and glycosuria may be encountered at highdosage, and nitrogen balance may not be achieved in extremely hypermetabolicpatients under these constraints. Concomitant insulin administration may berequired to minimize glycosuria. Daily laboratory monitoring is essential.

Useof an infusion pump is advisable to maintain a steady infusion rate duringcentral venous infusion.

B. Peripheral Nutrition

Inpatients for whom central venous catheterization is not advisable, proteincatabolism can be reduced by peripheral use of diluted Tonocal Liquid (Lysine)^® 15%plus non-protein calorie sources. Dilution of 250 mL Tonocal Liquid (Lysine)^® 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 ofthe veins. Intravenous fat emulsion can be infused separately or simultaneously;if infused simultaneously the fat emulsion will provide a dilution effectupon the osmolarity while increasing the energy supply.

Parenteraldrug products should be inspected visually for particulate matter and discolorationprior to administration, whenever solution and container permit.

Toreduce the risk of bacterial contamination, all intravenous administrationsets should be replaced at least every 24 hours. Usage of admixtures mustbe initiated within 24 hours after mixing. If storage is necessary duringthis 24 hour period, admixtures must be refrigerated and completely used within24 hours of beginning administration.
