Adequate levels of growth hormone in the body are needed to help bodies function properly, even after you’re done growing. It plays an important role in stimulating the liver and other tissues to secrete IGF-1, a protein which is needed to support muscle growth and metabolic functions.1
Symptoms of a possible growth hormone deficiency in adults include:2
- A higher level of body fat
- Less muscle (lean body mass)
- Reduced bone density
What is Saizen® (somatropin) for injection?
Saizen® (somatropin) for injection is a human growth hormone produced by recombinant DNA technology and is used when the body doesn’t produce growth hormone on its own. It is a type of treatment called growth hormone replacement therapy and is available by prescription only. The structure of the growth hormone used in treatment is identical to the growth hormone produced by the pituitary gland.
What does Saizen® do?
Saizen® is used for growth hormone therapy to replace the hormone that the body fails to produce on its own. It works to stimulate skeletal growth, increase the number and size of skeletal muscle cells, influence the size and function of internal organs and has important effects on metabolism.
Saizen® is approved to treat both children and adults.
In 2004, the FDA approved Saizen® for the replacement of endogenous growth hormone in adults with growth hormone deficiency who meet either of the following two criteria:
- Adult Onset: Patients who have growth hormone deficiency, either alone or associated with multiple hormone deficiencies (hypopituitarism), as a result of pituitary disease, hypothalamic disease, surgery, radiation therapy, or trauma; or
- Childhood Onset: Patients who were growth hormone deficient during childhood as a result of congenital, genetic, acquired, or idiopathic causes.
