VIOGENTROPIN PEN 50IU is a Recombinant Human Growth Hormone (Somatropin), a protein that is manufactured to be nearly identical to the main form of the naturally occurring human growth hormone. This hormone can stimulate tissue growth, linear growth (height), and protein, carbohydrate, lipid, and mineral metabolism. It has approved indications in both the adult and pediatric populations. Recombinant human growth hormone is used in the pediatric population to treat short stature due to growth hormone deficiency (including idiopathic [of unknown cause] growth hormone deficiency), Turner syndrome, Noonan syndrome, Prader-Willi syndrome, short stature homeobox-containing gene (SHOX) deficiency, chronic renal insufficiency, idiopathic short stature and children small for gestational age.
