Recombinant Human Growth Hormone (Somatropin)
Somatropin is a recombinant DNA-derived version of human somatotropin (growth hormone), identical in structure to the natural pituitary hormone. It is used primarily to treat growth hormone deficiency in children and adults. Classified under HTS 2937.11.00.00 as a structural analogue of somatotropin used primarily as a hormone.
Somatrem (Methionyl Human Growth Hormone)
Somatrem is a structurally modified form of human somatotropin with an extra methionine residue at the N-terminus, making it a derivative used for growth hormone replacement therapy. This analogue maintains the biological activity of natural somatotropin. Falls under HTS 2937.11.00.00 due to its classification as a somatotropin derivative used primarily as a hormone.
Somatrogon (Long-Acting Growth Hormone)
Somatrogon is a long-acting structural analogue of somatotropin created by linking human growth hormone to a CTP (C-terminal peptide) sequence from hCG beta subunit. This modification extends its half-life for weekly dosing in growth hormone deficiency. Classified in HTS 2937.11.00.00 as a chain-modified polypeptide analogue used primarily as a hormone.
Pegylated Somatotropin (PEG-GH)
Pegylated growth hormone is human somatotropin conjugated with polyethylene glycol (PEG) to extend its circulating half-life and reduce injection frequency. This structural modification creates a derivative used primarily for growth hormone therapy. HTS 2937.11.00.00 applies to such chain-modified polypeptide hormone analogues.
Mecasermin (Recombinant IGF-1)
Mecasermin is recombinant insulin-like growth factor 1 (IGF-1), a structural analogue closely related to the somatotropin/IGF-1 axis used in severe primary IGF-1 deficiency. While IGF-1 mediates somatotropin effects, its classification follows chapter notes for hormone analogues. HTS 2937.11.00.00 includes such polypeptide hormones used primarily in growth regulation.
Human Growth Hormone Reference Standard USP
USP reference standard of recombinant somatotropin used for quality control, assay calibration, and standardization in pharmaceutical manufacturing of growth hormone products. Meets pharmacopeial specifications for identity, potency, and purity. Classified under HTS 2937.11.00.00 as authentic somatotropin used in hormone-related applications.
