Norditropin® Cartridges
[somatropin (rDNA origin)] for Injection


Norditropin is a polypeptide hormone of recombinant DNA origin. The hormone is synthesized by a special strain of E. coli bacteria that has been modified by the addition of a plasmid which carries the gene for human growth hormone. Norditropin contains the identical sequence of 191 amino acids constituting the naturally occurring pituitary human growth hormone with a molecular weight of about 22,000 Daltons.

Norditropin is supplied as a sterile solution for subcutaneous injection in ready-to-administer prefilled pens with a volume of 1.5 mL or 3 mL.
