What is Felypressin?

Plain description, key identifiers and synonyms

Felypressin is 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 than 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. It has a role as a vasoconstrictor agent and a vasopressin receptor agonist.
