All current growth hormone therapy products contain somatropin as the active ingredient. The protein molecule of the manufactured growth hormone is identical to the natural human growth hormone produced by the pituitary gland.14
Different products come in different concentrations of somatotropin, storage requirements and preservative content. 14 Some products come in freeze-dried powder that has to be dissolved or reconstituted in a special fluid while others are available as a pre-mixed solution. New delivery systems using auto-injectors and needle-free devices are now available.
Parents and children may prefer one growth hormone therapy over another for convenience of preparation and storage, or ease of use of a particular device.31 Discuss your concerns and needs with your doctor so that the best treatment may be chosen for your child’s situation.
