Somatuline Autogel (Lanreotide) belongs to the class of medications called somatostatin analogues. Somatostatin is a hormone produced by the body that controls many processes in the body by blocking the action of other hormones.

Somatuline Autogel (Lanreotide) is used to treat acromegaly, a condition where the body produces too much growth hormone, resulting in overgrowth of the hands, feet, and face. It works by lowering the levels of growth hormone and insulin-like growth factor-1. Somatuline Autogel (Lanreotide) also blocks the release of some gastrointestinal hormones and intestinal secretions.

Somatuline Autogel (Lanreotide) is also used to treat a type of cancer called enteropancreatic neuroendocrine tumour. It works by delaying the growth of these tumours. Somatuline Autogel (Lanreotide) is also used to treat adults with Carcinoid Syndrome, a condition where cancerous neuroendocrine tumours release proteins into the blood stream which results in Diarrhea and flushing.

Somatuline Autogel (Lanreotide) may be available under multiple brand names and/or in several different forms.
