Video: Liquid Crystal Formulation
Unique liquid crystal formulation1
Lanreotide molecules organize into nanotube structures and correlate with the controlled release properties of Somatuline Depot4
Liquid Crystal Formulation
- A high density of nanotubes allows for a low injection volume in the ready-to-use prefilled syringe. It is believed that lanreotide forms a depot that functions as a reservoir for the drug between extended doses¹,⁴
- Lanreotide is slowly released, enabling once-monthly delivery via deep subcutaneous injection. Lanreotide passively diffuses toward the surrounding tissues and is absorbed into the bloodstream¹
Targeted affinity for the receptors that affect GH and IGF-11,5
- Lanreotide, the active component of Somatuline Depot, is an octapeptide analog of natural somatostatin. The mechanism of action of lanreotide is believed to be similar to that of natural somatostatin
- Lanreotide acts as a specific and potent type 2 and type 5 somatostatin receptor (SSTR) agonist with a reduced binding affinity for SSTRs 1, 3, and 41
- Human SSTRs 2 and 5 are believed to be the primary receptor sites responsible for GH inhibition1
IMPORTANT SAFETY INFORMATION & INDICATION
- SOMATULINE DEPOT is contraindicated in patients with hypersensitivity to lanreotide. Allergic reactions (including angioedema and anaphylaxis) have been reported following administration of lanreotide.
Warnings and Precautions
- Cholelithiasis and Gallbladder Sludge
- SOMATULINE DEPOT may reduce gallbladder motility and lead to gallstone formation.
- Periodic monitoring may be needed.
- If complications of cholelithiasis are suspected, discontinue SOMATULINE DEPOT and treat appropriately.
- Hypoglycemia or Hyperglycemia
- Patients treated with SOMATULINE DEPOT may experience hypoglycemia or hyperglycemia.
- Blood glucose levels should be monitored when SOMATULINE DEPOT treatment is initiated, or when the dose is altered, and antidiabetic treatment should be adjusted accordingly.
- Cardiovascular Abnormalities
- SOMATULINE DEPOT may decrease heart rate.
- In cardiac studies with acromegalic patients, the most common cardiac adverse reactions were sinus bradycardia, bradycardia, and hypertension.
- In patients without underlying cardiac disease, SOMATULINE DEPOT may lead to a decrease in heart rate without necessarily reaching the threshold of bradycardia.
- In patients suffering from cardiac disorders prior to treatment, sinus bradycardia may occur. Care should be taken when initiating treatment in patients with bradycardia.
- Thyroid Function Abnormalities
- Slight decreases in thyroid function have been seen during treatment with lanreotide in acromegalic patients.
- Thyroid function tests are recommended where clinically appropriate.
- Monitoring/Laboratory Tests: In acromegaly, serum GH and IGF-1 levels are useful markers of the disease and effectiveness of treatment.
Most Common Adverse Reactions
- Adverse reactions in >5% of patients who received SOMATULINE DEPOT were diarrhea (37%), cholelithiasis (20%), abdominal pain (19%), nausea (11%), injection-site reactions (9%), constipation (8%), flatulence (7%), vomiting (7%), arthralgia (7%), headache (7%), and loose stools (6%).
- SOMATULINE DEPOT may decrease the absorption of cyclosporine (dosage adjustment may be needed); increase the absorption of bromocriptine; and require dosage adjustment for bradycardia-inducing drugs (e.g., beta-blockers).
- Lactation: Advise women not to breastfeed during treatment and for 6 months after the last dose.
- Moderate to Severe Renal and Hepatic Impairment: See full prescribing information for dosage adjustment in patients with acromegaly.

SOMATULINE® DEPOT (lanreotide) is a somatostatin analog indicated for the long-term treatment of patients with acromegaly who have had an inadequate response to surgery and/or radiotherapy, or for whom surgery and/or radiotherapy is not an option. The goal of treatment in acromegaly is to reduce growth hormone (GH) and insulin growth factor-1 (IGF-1) levels to normal.
