Usage of Lanreotide

Lanreotide is an injectable medication containing a man-made (synthetic octapeptide) version of a hormone produced by your body called somatostatin. Somatostain regulates many process in your body.

Somatostain is also called growth hormone inhibiting hormone, because it decreases the amount of other hormones that you secrete. It also inhibits the ability of some cells to grow and survive. Lanreotide is thought to work like natural somatostain.

Lanreotide is used to treat acromegaly, a hormonal disorder that causes too much growth hormone. It is also used to treat certain neuroendocrine tumors (NETs) and carcinoid syndrome, which can occur in people with NETs. NETs are a type of cancer that starts in the neuroendocrine system, which produces and releases hormones that control many functions in your body.

Lanreotide is a somatostatin analog that comes in a depot formulation for suBCUTAneous injection. This means that it is injected into the fatty tissue just beneath the skin and the drug is released over a prolonged period of time.

A branded version of lanreotide was approved by the US Food and Drug Administration (FDA) in 2007 and it is marketed under the brand name Somatuline Depot by Ipsen Biopharmacueticals. In 2021, a company called Cipla was also granted FDA approval for its version of lanreotide injection through the New Drug Application process (NDA).
