Demoxytocin (INN) (brand names Sandopart, Odeax, Sandopral), also known as desaminooxytocin or deaminooxytocin, as well as 1-(3-mercaptopropanoic acid)oxytocin ([Mpa1]OT), is an oxytocic peptide drug that is used to induce labor,[1] promote lactation,[2] and to prevent and treat puerperal (postpartum) mastitis (breast inflammation).[3] Demoxytocin is a synthetic analogue of oxytocin and has similar activities,[4] but is more potent and has a longer half-life in comparison.[2][1] Unlike oxytocin, which is given via intravenous injection, demoxytocin is administered as a buccal tablet formulation.[2][5]

The drug was first synthesized in 1960 and was introduced into clinical practice in 1971 by Sandoz.[6][7] It is marketed in several European countries, including Italy, Czechoslovakia, and Poland.[8][6][2] It has the amino acid sequence Mpa-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH2 (Mpa = β-mercaptopropionic acid),[1] and is an analogue of oxytocin wherein the leading cysteine is replaced with β-mercaptopropionic acid.[1]
