Somatropin (rhGH)
Somatropin is recombinant human growth hormone. Its approved uses depend on the named product, clinical diagnosis, and age group.
At a glance
- Evidence stage
- Approved use
- Regulatory status
- FDA-approved somatropin products have distinct indications; NORDITROPIN covers specified growth disorders and adult GHD, while SEROSTIM treats HIV-associated wasting/cachexia.
- Research context
- Somatropin is recombinant human growth hormone. Its approved uses depend on the named product, clinical diagnosis, and age group.
What this is
- Somatropin is recombinant human growth hormone. Its approved uses depend on the named product, clinical diagnosis, and age group.
What this isn't
- A recommendation to use, prepare, combine, or administer a product
- Evidence that a related molecule or a differently formulated product has the same effects
Somatropin is recombinant human growth hormone. Its approved uses depend on the named product, clinical diagnosis, and age group.
Somatropin reproduces the human growth-hormone signal, including stimulation of IGF-1, protein metabolism, and skeletal growth while growth plates remain open. NORDITROPIN's label covers pediatric GHD and selected syndromic or other short-stature conditions, as well as adult GHD. Those indications should not be transferred automatically to every somatropin brand. NORDITROPIN label.
Evidence limits
How to read the evidence
SEROSTIM's wasting indication is distinct from its unapproved use for HIV-related fat redistribution or general aging. Lean-mass changes are not equivalent to improved survival, and the short trial did not show improved quality of life. A reader should identify the exact formulation and indication before interpreting any growth-hormone study. SEROSTIM label; trial results.
