Medication Summary

Analogs of somatostatin are the most effective medical therapies for GH excess. Dopamine-receptor agonists are best used as adjuvant treatments.

Somatostatin analogs

Class Summary

Like natural somatostatin, octreotide inhibits the secretion of GH, insulin, and glucagon. After an intravenous administration, basal serum GH, insulin, and glucagon levels fall. Octreotide also inhibits PRL release by means of vasoactive intestinal peptide (VIP)-mediated and TRH-mediated secretion of PRL. Octreotide is used to treat acromegaly and several hormone-secreting tumors.

Octreotide (Sandostatin, Sandostatin LAR)

 

Effectively lowers serum GH and IGF-I concentrations; may shrink tumor. Forty times more potent than native somatostatin to inhibit GH secretion. Available in immediate-release (Sandostatin) or long-acting depot (Sandostatin LAR) form.

Dopamine agonists

Class Summary

Dopamine-receptor agonists are other pharmacologic options. However, these drugs are effective in only a few patients. Cabergoline is well tolerated.

Bromocriptine (Parlodel)

 

Dopamine agonist most often used to treat GH and PRL excess. Safe when administered to a child for extended period.

Cabergoline (Dostinex)

 

Potent dopamine agonist with prolonged duration of action. Inhibits PRL secretion more than bromocriptine.

GH-receptor antagonist

Class Summary

This novel class of drugs have demonstrated efficacy to suppress GH and IGF-I levels.

Pegvisomant (Somavert, B2036-PEG)

 

Recombinant DNA analog of human GH structurally altered to act as GH receptor antagonist. Selectively binds to GH receptors on cell surfaces, blocking endogenous GH binding. Thus interferes with GH signal transduction, decreasing levels of IGF-I, IGFBP-3, and acid-labile subunit.
