酢酸リプレシンCAS:50-57-7

Lypressin is a synthetic analog of the pituitary hormone, argipressin. Its action is mediated by the vasopressin receptor V2. It has prolonged antidiuretic activity, but little pressor effects. It also modulates levels of circulating Factor VIII and Von Willebrand factor. Lypressin is a hormone used to prevent or control the frequent urination, increased thirst, and loss of water associated with diabetes insipidus (water diabetes).

Lypressin is the porcine antidiuretic hormone (vasopressins). It is a cyclic nonapeptide that differs from arg-vasopressin by one amino acid, containing a lysine at residue 8 instead of an arginine. Lys-vasopressin is used to treat diabetes insipidus or to improve vasomotor tone and blood pressure.
