Abstract

The invention relates to a terlipressin acetate nasal cavity spray and a preparation method thereof. The spray is composed by terlipressin acetate, absorption enhancer, osmotic pressure regulator, preservative and PH regulator. The preparation method of the spray mainly comprises raw material preparing, dissolving, bottle washing, filling, packing and the like. The spray has the main functions of contracting smooth muscles of visceral vessels and reducing blood flow volume of the viscera, accordingly, the portal vein blood flow and portal vein pressure are reduced, and meanwhile, the spray can be used for the smooth muscles of the esophagus and the uterus. The spray is convenient to dose, has high bioavailability, and is beneficial to patients to accept.

Description

Technical field: [0001] The invention relates to the field of preparations, in particular to a nasal spray of terlipressin acetate and a preparation method thereof. Background technique: [0002] Terlipressin is a synthetic polypeptide and an analog of the hormone secreted by the posterior pituitary gland. It is a new type of synthetic long-acting vasopressin. It is a prodrug and has no activity itself. After the action of aminopeptidase, the three glycyl residues at the N-terminus are removed, and the active lysine vasopressin is slowly released. The main function of terlipressin is to contract visceral vascular smooth muscle and reduce visceral blood flow, thereby reducing portal vein blood flow and portal vein pressure. It can also act on smooth muscles such as the esophagus and uterus. The clinical dosage form of this drug is mainly injection. The use of injection requires a specific environment and is generally limited to hospitals. It is inconvenient to use, and the p...
