Levonorgestrel cyclobutylcarboxylate (or levonorgestrel 17β-cyclobutylcarboxylate; developmental code name HRP-001) is a progestin and a progestogen ester which was studied for potential use as an injectable hormonal contraceptive but was never marketed.[1][2][3][4][5][6][7][8][9][10] It was developed by the World Health Organization's Special Programme on Human Reproduction in the 1980s.[1][2][9]Analogues of levonorgestrel cyclobutylcarboxylate include levonorgestrel butanoate (HRP-002) and levonorgestrel cyclopropylcarboxylate (HRP-003).[1][2][3]
