Lanreotide

A depot somatostatin analog, similar in action to octreotide.

AnalogEstablishedBased on SomatostatinCompare lineage

Identity

Class
Somatostatin analog (cyclic octapeptide)
Source
Synthetic analog of somatostatin
Receptor
Somatostatin receptors (SSTR2 and SSTR5 preferential)

Key properties

Molecular weight
~1,096.3 Da
Half-life (native)
depot-dominant (autogel acts over weeks)

Approximate values for the native hormone. Engineered analogs are often deliberately larger and far longer-acting.

Mechanism

Lanreotide is a somatostatin analog formulated as a long-acting depot (autogel) that releases over weeks, suppressing growth hormone and neuroendocrine secretion much like octreotide. Its prolonged depot kinetics are the practical contrast with the native peptide's minutes-long half-life.

Reference notes

  • Delivered as an extended-release depot acting over weeks.
  • Shares octreotide's SSTR2/5-preferential profile.
  • Used in acromegaly and neuroendocrine tumors.
