The U.S. Food and Drug Administration has approved Accretropin (somatropin (rDNA origin)) Injection, a recombinant human growth hormone indicated for treatment of pediatric patients who have growth failure due to an inadequate secretion of normal endogenous growth hormone. Accretropin is also indicated for the treatment of short stature associated with Turner Syndrome in pediatric patients whose epiphyses are not closed.
Accretropin is identical in sequence to authentic human growth hormone of pituitary origin. Natural human growth hormone is a protein produced by the pituitary gland that acts on the ends of the long bones of the body (epiphyses) until the onset of puberty and promotes growth to normal stature. A deficiency of this hormone during childhood results in abnormally small stature.
Turner Syndrome is an X-chromosome-linked genetic disorder in girls that results in short stature and infertility.
