Epelsiban (INN,[1] USAN,[2] code name GSK-557,296-B) is an orally bioavailable drug which acts as a selective and potent oxytocin receptor antagonist (Ki = 0.13 nM).[3][4] It was initially developed by GlaxoSmithKline (GSK) for the treatment of premature ejaculation in men[5][6] and then as an agent to enhance embryo or blastocyst implantation in women undergoing embryo or blastocyst transfer associated with in vitro fertilization (IVF).,[7] and was also investigated for use in the treatment of adenomyosis.[8]
