Использование

Felypressin(Octapressin) is a vasopressin 1 agonist and a peptide containing eight amino acids including cystine. Felypressin is used as a vasoconstrictor.

Определение

ChEBI: A synthetic nonapeptide comprising cysteinyl, phenylalanyl, phenylalanyl, glutaminyl, asparaginyl, cysteinyl, prolyl, lysyl, and glycinamide residues in sequence, with a disulfide bridge joining the two cysteine residues. Its antidiuretic effects are less han those of vasopressin. It is used as a vasoconstrictor in local anaesthetic injections for dental use, and is an ingredient of preparations that have been used for treatment of pain and inflammation of the mouth.

Общее описание

Felypressin, 2-L-phenylalanine-8-L-lysinevasopressin, has relatively low antidiuretic activity and littleoxytocic activity. It has considerable pressor (i.e., vasoconstrictor)activity, which differs from that of epinephrine (i.e.,following capillary constriction in the intestine it lowers thepressure in the vena portae, whereas epinephrine raises theportal pressure). Felypressin also causes increased renalblood flow in the cat, whereas epinephrine brings about afall in renal blood flow. Felypressin is five times more effectiveas a vasopressor than is lysine vasopressin and is recommendedin surgery to minimize blood flow, especially inobstetrics and gynecology.
