Quick Summary
A synthetic analogue of the first 29 amino acids of growth hormone releasing hormone, studied in growth-hormone-deficient children and used as a pituitary diagnostic. Its FDA approvals were withdrawn in 2009. Available from 46 vendors, priced from $22.00 to $255.00.
Research: Thorner et al, J Clin Endocrinol Metab 1996;81:1189-1196 (PMID 8772599) reported that at 6 months 74% of the growth-hormone-deficient children treated were considered to have a good response to GHRH, with height velocity rising from 4.1 plus or minus 0.9 to 8.0 plus or minus 1.5 cm per year. The paper's wording is a clinician-rated good response, not a measured growth-rate increase in 74% of children.
Side effects: From the Geref label: injection site pain and redness, facial flushing, headache, dizziness, nausea
Previously FDA-approvedGeref Diagnostic (NDA 19-863) approved 28 December 1990 and Geref (NDA 20-443) approved 26 September 1997. EMD Serono notified the FDA of discontinuation in July and December 2008, and approval was withdrawn effective 18 June 2009 (74 FR 23407). The FDA determined the products were not withdrawn for reasons of safety or effectiveness.
