teduglutide (rDNA origin)(te-due-gloo-tide) ,
Pregnancy Category: B
ClassificationTherapeutic: temporary class
Treatment of short bowel syndrome in adult patients who are dependent on parenteral nutrition.
Increases intestinal and portal blood flow, inhibits gastric acid secretion.
Binding to receptors causes release of insulin-like growth factor, nitric oxide and keratinocyte growth factor.
Improved gastrointestinal absorption of fluids and nutrients with a decreased need for parenteral nutrition/IV support.
Absorption: 88% absorbed following subcutaneous administration.
Metabolism and Excretion: Probably degraded into small peptides and amino acids; primarily renally eliminated.
Half-life: 2 hr.
Time/action profile (↓ in parenteral nutrition/IV volume need)
|subcut||within 1 mo||unknown||unknown|
Contraindicated in: Lactation: Breastfeeding should be avoided.
Use Cautiously in: Patients with history of or ↑ risk of gastrointestinal malignancy; Underlying cardiovascular disease (fluid overload may be problematic); CCr <50 mL/min (dose ↓ required); Biliary and pancreatic disease; Geriatric: Elderly patients may be ↑ sensitive to drug effects; Obstetric: Use during pregnancy only if clearly needed; Pediatric: Safety and effectiveness not established.

- intestinal obstruction (life-threatening)
- abdominal distention (most frequent)
- abdominal pain (most frequent)
- nausea (most frequent)
- stoma complications (most frequent)
- appetite disorders
Fluid and Electrolyte
- fluid overload (most frequent)

Drug-Drug interactionMay ↑absorption of orally administered medications; cautiously monitor drugs with narrow therapeutic indices or drugs requiring careful titration.
Subcutaneous (Adults) 0.05 mg/kg once daily.
Renal ImpairmentSubcutaneous (Adults) CCr <50 mL/min—0.025 mg/kg once daily.
Lyophilized powder for reconstitution: 5 mg/vial with 0.5 mL Sterile Water for Injection in a pre-filled syringe
- Obtain a colonoscopy of entire colon with removal of polyps within 6 mo prior to starting teduglutide. Follow-up colonoscopy is recommended at end of 1 yr on teduglutide. If no polyps found, repeat at least every 5 yrs. If polyps found follow recommended guidelines.
- Monitor for fluid overload, especially in patients with underlying cardiovascular disease; may require adjustment in parenteral support.
- Lab Test Considerations: Monitor bilirubin, alkaline phosphatase, lipase, and amylase within 6 mo of starting and every 6 mo after starting therapy. If clinically meaningful ↑ occurs further diagnostic work-up is recommended.
Potential Nursing DiagnosesImbalanced nutrition: less than body requirements (Indications)
- Reconstitute each vial with 0.5 mL of preservative-free Sterile Water for Injection slowly injected from pre-filled syringe. Allow vial to stand for 30 seconds, then gently roll between palms for 15 seconds; do not shake. Allow mixed contents to stand for 2 min. Inspect for undissolved powder and gently roll again until dissolved. If product remains undissolved after second attempt, do not use. Solution should be clear and colorless to light straw; do not administer solutions that are discolored or contain a precipitate. Vial contains 0.38 mL of reconstituted solution with up to 3.8 mg of teduglutide. Administer within 3 hrs of reconstitution. Store in refrigerator; do not freeze. Discard unused solution.
- Subcutaneous: Inject subcut once daily in thighs, arms, and quadrants of the abdomen. Rotate sites daily. Do not inject IM or IV.
- Discontinuation may result in fluid and electrolyte imbalance; monitor closely.
- Instruct patient in correct technique for injection and disposal of equipment. Take missed doses as soon as remembered in same day; do not take 2 doses in one day. Advise patient to read Medication Guide before starting and with each Rx refill in case of changes.
- Advise patient that injection site reaction may occur, but if severe reaction or severe rash occurs, notify health care professional.
- Inform patient of risk of accelerated neoplastic growth, colorectal polyps, and small bowel neoplasia. Advise patient to report signs and symptoms.
- Advise patient to notify health care professional if signs and symptoms of intestinal obstruction (abdominal pain, swelling of stoma) occur. May require temporary discontinuation of teduglutide.
- Instruct patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and consult health care professional before taking any new medications. Oral medications may be absorbed more completely and may require dose adjustment.
- Advise female patient to notify health care professional if pregnancy is planned or suspected or if breastfeeding.
- Emphasize the importance of routine lab tests and colonoscopies to monitor for adverse effects.
- Improved gastrointestinal absorption of fluids and nutrients with a decreased need for parenteral nutrition/IV support.
