Curator's Comment: description was created based on several sources, including: DOI: 10.1023/A:1008898216113 | https://www.ncbi.nlm.nih.gov/pubmed/16939388

Avorelin is a superagonist of natural luteinizing-hormone-releasing-hormone. Avorelin has been formulated in high molecular weight polylactic glycolic acid to afford protracted and continuous release of the peptide from subcutaneous implants. Avorelin has been in phase II clinical trials by Mediolanum for the treatment of prostate cancer, breast cancer and endometriosis. However, this research has been discontinued. Adverse events mainly related to androgen suppression (hot flushes, decreased libido and impotence) or the nature of the disease (skeletal pain).
