Human vasopressin, also called antidiuretic hormone, arginine vasopressin or argipressin, is a hormone synthesized from the AVP gene as a peptide prohormone in neurons in the hypothalamus, and is converted to AVP. It plays a key role in regulating the body's retention of water and constriction of blood vessels. Vasopressin is stored in the posterior pituitary gland and is released in response to triggers such as dehydration or low blood pressure. As a medication, vasopressin is used to treat conditions like diabetes insipidus and manage low blood pressure (hypotension) in patients experiencing septic shock.

During the production and storage of vasopressin, impurities may form and must be carefully controlled to ensure the medication’s safety and efficacy. Regulatory authorities such as the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) provide guidelines for acceptable impurity levels in vasopressin formulations.
Vasopressin’s primary function is to regulate the body’s retention of water by increasing water reabsorption in the kidneys. It also constricts blood vessels, helping to raise blood pressure when it drops too low.
Vasopressin is triggered in response to dehydration, low blood volume, and low blood pressure. Stress and certain social behaviors, such as bonding and territoriality, can also increase vasopressin levels in men.
While vasopressin is not typically known as a “love hormone,” like oxytocin, it is involved in social behaviors such as bonding, aggression, and territoriality, particularly in men. Research has shown that vasopressin plays a role in partner bonding and social recognition.
Vasopressin is used as a medication to treat conditions such as diabetes insipidus, which is characterized by excessive thirst and urination due to an inability to conserve water. It is also used to manage low blood pressure in cases of septic shock and can be used during surgery to control bleeding by constricting blood vessels.
