Octreotide (Sandostatin) Mechanism of Action

An 8-amino-acid synthetic analog of somatostatin that binds somatostatin receptors (primarily SSTR2 and SSTR5), suppressing growth hormone, glucagon, insulin, and several gastrointestinal hormones. Longer half-life than native somatostatin enables therapeutic use.

Octreotide (Sandostatin) — Frequently Asked Questions

Lanreotide versus octreotide — which has better outcomes?+

Randomized and observational studies in acromegaly and neuroendocrine tumors show broadly equivalent efficacy for lanreotide autogel and octreotide LAR at approved dose ranges — comparable biochemical response, tumor stabilization, and symptom control. Selection is typically driven by injection route (deep SC vs IM), self- or partner-administration preference, and tolerability, not raw efficacy.

Octreotide and lanreotide — are they interchangeable?+

They are the same drug class (somatostatin analogues, SSAs) but not identical drugs. Both bind somatostatin receptors (mainly SSTR2 and SSTR5) with comparable affinity profiles. Published switch protocols exist in both directions, but interchange is a clinical decision — not a like-for-like substitution.

What is the difference between octreotide and lanreotide administration?+

Octreotide LAR is a 6–8 mL intramuscular gluteal injection reconstituted from powder, administered by a healthcare professional. Lanreotide autogel is a pre-filled 0.5 mL deep-subcutaneous injection into the upper outer buttock and can be administered by a trained partner or, in some regions, by the patient.
