Also known as GH-N, Growth hormone, GH, Pituitary growth hormone, Somatotropin precursor, Growth hormone 1, B2036-PEG

Pegvisomant, sold under the brand name Somavert, is a growth hormone receptor antagonist used in the treatment of acromegaly. It is primarily used if the pituitary gland tumor causing the acromegaly cannot be controlled with surgery or radiation, and the use of somatostatin analogues is unsuccessful, but is also effective as a monotherapy. It is delivered as a powder that is mixed with water and injected under the skin.
