FULL PRESCRIBING INFORMATION
1 INDICATION AND USAGE
NutreStore® [L-glutamine powder for oral solution] is indicated for the treatment of Short Bowel Syndrome (SBS) in patients receiving specialized nutritional support when used in conjunction with a recombinant human growth hormone that is approved for this indication [see Dosage and Administration (2) ].
NutreStore and recombinant human growth hormone (rhGH) therapy should be used in conjunction with optimal management of SBS. Optimal management of SBS may include a specialized oral diet, enteral feedings, parenteral nutrition, fluid and micronutrient supplements. A specialized oral diet may consist of a high carbohydrate, low-fat diet, adjusted for individual patient requirements and preferences.
Routine monitoring of renal and hepatic function is recommended in patients receiving NutreStore and intravenous parenteral nutrition (IPN), particularly in those with renal or hepatic impairment. Glutamine is metabolized to glutamate and ammonia, which may increase in patients with hepatic dysfunction.
The safety and efficacy of NutreStore have not been studied beyond 16 weeks of treatment.
2 DOSAGE AND ADMINISTRATION
NutreStore should be administered as a cotherapy with rhGH (see prescribing information for somatropin [rDNA origin)] for injection) followed by continued NutreStore for up to 16 weeks.
The recommended dosage of NutreStore is 30 g daily in divided doses (5 g taken 6 times each day orally) for up to 16 weeks. Each dose of NutreStore (5 g) should be reconstituted in 8-oz (250-mL) of water prior to consumption.
NutreStore should be taken with meals or snacks at 2- to 3-hour intervals while awake. The volume of water may be varied according to the patient's preference. In the event of a patient's transient intolerance to oral intake, a dose may be delayed for up to 2 hours.
3 DOSAGE FORMS AND STRENGTHS
NutreStore is supplied in preprinted paper-foil-plastic laminate packets containing 5 g of L-glutamine powder.
4 CONTRAINDICATIONS
None.
5 WARNINGS AND PRECAUTIONS
5.1 Increased Serum Ammonia and Glutamate
Glutamine is metabolized to glutamate and ammonia, which may increase in patients with hepatic dysfunction. Therefore, routine monitoring of renal and hepatic function is recommended in patients receiving intravenous parenteral nutrition (IPN) and NutreStore, particularly in those with renal or hepatic impairment.

During the initial 4-week treatment period, 100% of patients receiving growth hormone with and without glutamine reported at least one AR, whereas 89% of patients receiving growth hormone placebo with glutamine reported at least one AR. During weeks 5 to 18, 81% of patients receiving growth hormone with glutamine, 80% of patients receiving growth hormone without glutamine and 78% of patients receiving growth hormone placebo with glutamine experienced at least one AR. There were no deaths in this study.
7 DRUG INTERACTIONS
Formal drug interaction studies have not been conducted.
8 USE IN SPECIFIC POPULATIONS
8.1 Pregnancy
Teratogenic Effects: Pregnancy Category C
Animal reproduction studies have not been conducted with glutamine. It is also not known whether glutamine can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Glutamine should be given to a pregnant woman only if clearly needed.
8.2 Labor and Delivery
The effect of L-glutamine on labor and delivery is unknown.
8.3 Nursing Mothers
It is not known whether L-glutamine is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when L-glutamine is administered to a nursing woman.
8.4 Pediatric Use
The safety and effectiveness of L-glutamine in pediatric patients have not been established.
8.5 Geriatric Use
The clinical trial enrolled SBS patients between the ages of ZO and 75 years. Only 8 of the 41 subjects evaluated were ≥65 years of age. The clinical trial of oral glutamine did not include sufficient numbers of subjects aged 65 years and over to determine if they respond differently than younger subjects. In general, dose selection for an elderly patient should be individualized, because of the greater frequency of decreased hepatic, renal, or cardiac function, as well as concomitant disease in this population.
8.6 Hepatic Impairment
Glutamine is metabolized to glutamate and ammonia, which may increase in patients with hepatic dysfunction. Therefore, routine monitoring of hepatic function is recommended in patients receiving intravenous parental nutrition (IPN) and NutreStore.
8.7 Renal Impairment
Glutamine is metabolized to glutamate and ammonia. Routine monitoring of renal function is recommended in patients receiving intravenous parental nutrition (IPN) and NutreStore.
10 OVERDOSAGE
Single oral doses of glutamine at about 20 to 22 g/kg, 8 to 11 g/kg, and 19 g/kg were lethal in mice, rats, and rabbits, respectively.
11 DESCRIPTION
NutreStore (L-glutamine powder for oral solution) for oral administration is formulated as a white crystalline powder in a paper-foil-plastic laminate packet. Each packet of NutreStore contains 5 g of L-glutamine. The amino acid glutamine is also known as (S)-2-aminoglutaramic acid, L-glutamic acid 5-amide, (S)-2,5-diamino-5-oxopentanoic acid, or L-glutamine. The molecular formula of glutamine is C5H10N2O3, and the molecular weight is 146.15 d. Glutamine has the following structural formula:
12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
L-glutamine has important functions in regulation of gastrointestinal cell growth, function, and regeneration. Under normal conditions, glutamine concentration is maintained in the body by dietary intake and synthesis from endogenous glutamate. Data from clinical studies indicate that the role of and nutritional requirements for glutamine during catabolic illness, trauma, and infection may differ significantly from the role of and nutritional requirements for glutamine in healthy individuals. Glutamine concentrations decrease and tissue glutamine metabolism increases during many catabolic disease states, and thus glutamine is often considered a "conditionally essential" amino acid.
12.2 Pharmacodynamics
When glutamine was administered in combination with rhGH to rats, villous height, bowel growth, plasma insulin-like growth factor I, and body weight were significantly higher than in rats treated with either glutamine or rhGH alone.
12.3 Pharmacokinetics
The pharmacokinetics of L-glutamine as described below are based on literature data in healthy subjects. The pharmacokinetics in patients with SBS have not been determined. The plasma glutamine concentrations in these patients following oral administration are expected to be highly variable depending on the length, segment, and presence/ absence of ileal-cecal valve for the remnant bowel.
Absorption
Following single dose oral administration of glutamine at 0.1 g/kg to six subjects, mean peak blood glutamine concentration was 1028 µM (or 150 mcg/mL) occurring approximately 30 minutes after administration. The pharmacokinetics following multiple oral doses have not been adequately characterized.
Distribution
After an intravenous bolus dose in three subjects, the volume of distribution was estimated to be approximately 200 mL/kg.
Metabolism
Endogenous glutamine participates in various metabolic activities, including the formation of glutamate, and synthesis of proteins, nucleotides, and amino sugars. Exogenous glutamine is anticipated to undergo similar metabolism.
Elimination
Metabolism is the major route of elimination for glutamine. Although glutamine is eliminated by glomerular filtration, it is almost completely reabsorbed by the renal tubules. After an IV bolus dose in three subjects, the terminal half-life of glutamine was approximately 1 hour.
Specific Populations
There are no studies to determine the effect of race, age, or gender on the pharmacokinetics of L-glutamine.
Drug-Drug Interactions
No drug-drug interaction studies have been conducted. Because metabolism of glutamine is mediated via non-CYP enzymes, glutamine pharmacokinetics are unlikely to be affected by other agents through CYP enzyme inhibition or induction.
13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
Long-term studies in animals have not been performed to evaluate the carcinogenic potential of L-glutamine. Studies to evaluate its potential for impairment of fertility or its mutagenic potential have not been conducted.
14 CLINICAL STUDIES
14.1 Short Bowel Syndrome
A randomized, controlled, 3-arm, double-blind, parallel-group clinical study evaluated the efficacy and safety of oral glutamine as a cotherapy with rhGH in subjects with SBS who were dependent on intravenous parenteral nutrition (IPN) for nutritional support. The primary endpoint was the change in weekly total IPN volume defined as the sum of the volumes of lPN, supplemental lipid emulsion (SLE), and intravenous hydration fluid. The secondary endpoints were the change in weekly IPN caloric content and the change in the frequency of IPN administration per week.
All subjects received a specialized oral diet (SOD) for the duration of the study. Following a two-week equilibration period, treatment was administered in a double blind manner. Group A (N=16) received rhGH for four weeks plus oral glutamine placebo for 16 weeks, Group B (N=16) received rhGH for four weeks plus oral glutamine for 16 weeks, and Group C (N=9), received rhGH placebo for four weeks plus oral glutamine for 16 weeks. The efficacy of glutamine was assessed by comparing the cotherapy (rhGH and oral glutamine) to rhGH alone.
After 4 weeks of treatment with subcutaneous rhGH (0.1 mg/kg/d) and oral glutamine (30 g/ d) (Group B), subjects with SBS reduced their requirement for IPN volume (-7.7 L/wk), IPN caloric content (-5751 kcal/wk), and weekly frequency of IPN administration (-4.2 d/wk).

Patient Information
NutreStore®
(NOO-tre-stor)
[L-glutamine powder for oral solution] (GLOO-tah-min)
Please read this leaflet carefully before you start to use NutreStore® and each time your prescription is refilled since there may be new information. The information in this leaflet does not take the place of regularly talking with your doctor or health care professional.
What is NutreStore®?
NutreStore® is the amino acid L-glutamine, identical to the L-glutamine that your body produces. NutreStore® is used together with a human growth hormone, approved for treating short bowel syndrome [SBS], in patients receiving a specialized diet tailored to meet their individual needs.
Why has my doctor prescribed NutreStore®?
Your doctor prescribed NutreStore® initially in combination with human growth hormone to help decrease your need for intravenous feedings. After treatment in combination with human growth hormone, you will continue to take NutreStore® alone to maintain the treatment effect. During your treatment with NutreStore® you will be taking up to 6 packets of NutreStore® a day. You will also receive instructions from your doctor or a dietitian on the proper diet you should follow during this treatment period as well as after your treatment is over. Please refer to the patient package leaflet available for human growth hormone for more information on how to take human growth hormone.
What should I tell my doctor before taking NutreStore®?
Tell your doctor about all of your conditions including if you:
- are pregnant or planning to become pregnant. It is not known if NutreStore® can harm your unborn baby.
- are breast feeding. It is not known if NutreStore® passes into your milk and if it can harm your baby. You should talk to your doctor about breastfeeding while taking NutreStore®.
- have liver or kidney problems. Your doctor may do blood tests to check your liver and kidney function while you are taking NutreStore®.
- are older than 65 years of age. Your dose of NutreStore® may need to be adjusted.
Tell your doctor about all the medicines you take including prescription medicines, non-prescription medicines, vitamins, or herbal supplements. It is not known if NutreStore® and other medicines can affect each other.
What should I avoid while taking NutreStore®?
- Pregnancy. You should talk to your doctor if you are planning to become pregnant while taking NutreStore®. It is not known whether NutreStore® can affect the ability of a woman to become pregnant. It is also not known whether NutreStore® can cause harm to a fetus when taken by a pregnant woman or if NutreStore® has an effect on labor and delivery.
- Breastfeeding. You should talk to your doctor before breastfeeding an infant while taking NutreStore®. It is not known whether the glutamine in NutreStore® can be passed to an infant in mother's milk, and it is not clear whether the drug could harm the infant if it is passed in mother's milk.
What are the possible side effects of NutreStore®?
Many patients taking NutreStore® and human growth hormone for the treatment of SBS experience side effects.
Whether or not you experience side effects, you and your doctor should periodically talk about your general health.
- Your doctor may want to monitor you more closely and ask you to have blood tests done more frequently.
Digestive system.
The possible side effects you may experience while taking NutreStore® include vomiting, hemorrhoids, pancreatitis, aggravation of Crohn's disease, gastric ulcer, and gastrointestinal fistula (opening between stomach and intestine).
The possible related symptoms you may experience while taking NutreStore® include urge to empty bowel, gas, abdominal pain, nausea, dry mouth and constipation.
These side effects and related symptoms may be similar to those you have experienced while being treated for SBS. You should talk to your doctor about these problems before starting an over-the-counter medication to treat these symptoms. It is important for you to follow your doctor's or dietitian's instructions on the type of diet best for you.
Please refer also to the patient package leaflet available for human growth hormone for more information on the possible benefits and side effects of human growth hormone.
Tell your doctor about any side effects that bother you or that do not go away.
These are not all the side effects with NutreStore®. For more information, ask your doctor or pharmacist.
How should I take NutreStore®?
NutreStore® should be taken up to 6 times a day (every 2 to 3 hours during the day) with a meal or snack. This should be continued every day for as long as your doctor prescribes. Each dose of NutreStore® should be prepared by pouring the contents of one packet into an 8-oz glass of water and stirring for approximately 1 minute.
