[News options and preparations in growth hormone therapy].

In the last twenty years, recombinant human Growth hormone (hrGH) has been available for the treatment of Growth Hormone Deficiency (GHD) in children and more recently in adults. However, the necessity of daily injections compromises the patient's compliance. Attempts to improve this compliance includes the use of pens and needle free devices, once the infusion pumps, not always physiologic, are of restricted use. When growth is the purpose of treatment, daily subcutaneous hrGH is still the most indicated. Nevertheless the expansion of GH replacement to new uses and especially in adults will need new preparations. Nowadays, the oral secretagogues have not proved efficacy to be used in clinical practice and the slow- release preparations of GH and GH releasing hormone that could improve the patient's compliance will need to be studied considering long term efficacy and safety.
