What Signifor LAR is used for
Signifor LAR is a prescription medicine used to treat patients with acromegaly.
Acromegaly is caused by an enlargement in the pituitary gland (a gland at the base
of the brain) called a pituitary adenoma. This leads the body to produce too much
of a hormone called growth hormone (GH). This overproduction of GH causes the body
to produce too much of another hormone called insulin-like growth factor-1 (IGF-1).
Normally, these hormones control growth of tissues, organs and bones.
Signifor LAR is a medicine containing a synthetic substance called pasireotide that
mimics the action of somatostatin, a substance normally found in the human body, which
can block the production of hormones such as GH and IGF-1. Signifor LAR is used instead
of somatostatin because its effects are stronger and last longer.
Signifor LAR binds to somatostatin receptors which are present in high number in the
brain in the pituitary gland where the excessive amount of growth hormone is produced.
By binding to these somatostatin receptors, Signifor LAR reduces the production of
GH and IGF-1 and may reduce the size of the adenoma.
Too much GH or IGF-1 leads to an increase in the size of bones and tissues, especially
in the hands and feet.
