Omnitrope is a medicine that contains the active substance called somatropin. It is available as a powder and solvent in the form of a solution for injection or a solution prepared in a cartridge .

Growth hormone is a pituitary-secreted substance (a gland at the base of the brain). It stimulates growth during childhood and adolescence and also affects the way the body manages proteins, lipids and carbohydrates. The active substance in Omnitrope, somatropin, is identical to the human growth hormone. It is produced by a method known as “recombinant DNA technology”: the hormone is created by a bacterium that has received a gene (DNA) that makes it able to produce it. Omnitrope replaces the natural hormone.
