Terlipressin is a synthetic peptide that is an analog of a hormone secreted by the posterior pituitary gland. The commonly used dosage form is terlipressin for injection, which is suitable for the treatment of esophageal variceal bleeding.
After injection, its triglycyl group will be cut off by enzymes in the body to slowly release active substances such as vasopressin, which can contract smooth muscles for up to 10 hours.
