Overview
11 DESCRIPTION Lanreotide Injection 60 mg/0.2 mL, 90 mg/0.3 mL, and 120 mg/0.5 mL is a prolonged-release formulation for deep subcutaneous injection. It contains the drug substance lanreotide acetate, a synthetic octapeptide with a biological activity similar to naturally occurring somatostatin, water for injection and acetic acid (for pH adjustment).
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Lanreotide, the active component of Lanreotide Injection, is an octapeptide analog of natural somatostatin. The mechanism of action of lanreotide is believed to be similar to that of natural somatostatin. 12.2 Pharmacodynamics Lanreotide has a high affinity for human somatostatin receptors (SSTR) 2 and 5 and a reduced binding affinity for human SSTR1, 3, and 4. Activity at human SSTR2 and 5 is the primary mechanism believed responsible for GH inhibition. Like somatostatin, lanreotide is an inhibitor of various endocrine, neuroendocrine, exocrine, and paracrine functions.
Indications
- 1 INDICATIONS AND USAGE Lanreotide Injection is a somatostatin analog indicated for: the long-term treatment of acromegalic patients who have had an inadequate response to or cannot be treated with surgery and/or radiotherapy. ( 1.1 ) the treatment of adult patients with unresectable, well- or moderately- differentiated, locally advanced or metastatic gastroenteropancreatic neuroendocrine tumors (GEP-NETs) to improve progression-free survival. ( 1.2 ) the treatment of adults with carcinoid syndrome; when used, it reduces the frequency of short-acting somatostatin analog rescue therapy. ( 1.

Dosage
2 DOSAGE AND ADMINISTRATION Administration ( 2.1 ): For deep subcutaneous injection only. Intended for administration by a healthcare provider. Administer in the superior external quadrant of the buttock. Alternate injection sites. Recommended Dosage ( 2.1 ) Acromegaly : 90 mg every 4 weeks for 3 months. Adjust thereafter based on GH and/or IGF-1 levels. See full prescribing information for titration regimen. GEP-NETs : 120 mg every 4 weeks. Carcinoid Syndrome : 120 mg every 4 weeks.
Contraindications
- 4 CONTRAINDICATIONS Lanreotide Injection is contraindicated in patients with history of a hypersensitivity to lanreotide. Allergic reactions (including angioedema and anaphylaxis) have been reported following administration of lanreotide [ see Adverse Reactions ( 6.3 )] . Hypersensitivity to lanreotide. ( 4 )
Side Effects
- 6 ADVERSE REACTIONS The following adverse reactions are discussed in greater detail in other sections of the labeling: Cholelithiasis and Complications of Cholelithiasis [see Warnings and Precautions ( 5.1 )] Hyperglycemia and Hypoglycemia [see Warnings and Precautions ( 5.2 )] Cardiovascular Abnormalities [see Warnings and Precautions ( 5.3 )] Thyroid Function Abnormalities [see Warnings and Precautions ( 5.4 )] Steatorrhea and Malabsorption of Dietary Fats [see Warnings and Precautions ( 5.
Interactions
- 7 DRUG INTERACTIONS Cyclosporine : Lanreotide Injection may decrease the absorption of cyclosporine. Dosage adjustment of cyclosporine may be needed. ( 7.2 ) Bromocriptine : Lanreotide Injection may increase the absorption of bromocriptine. ( 7.3 ) Bradycardia-Inducing Drugs (e.g., beta-blockers) : Lanreotide Injection may decrease heart rate. Dosage adjustment of the coadministered drug may be necessary. ( 7.3 ) 7.1 Insulin and Oral Hypoglycemic Drugs Lanreotide, like somatostatin and other somatostatin analogs, inhibits the secretion of insulin and glucagon.
