Argipressin is a neurohypophysial hormone from the vasopressin hormone family. Its two primary functions are to retain water in the body and to constrict blood vessels. The antidiuretic action of Argipressin is ascribed to increase in reabsorption of water by the renal tubules. Argipressin can cause contraction of smooth muscle of the gastrointestinal tract, gall bladder, urinary bladder and all parts of the vascular bed, especially the capillaries, small arterioles and venules with less effect on the smooth musculature of the large veins. Agripressin for injections is used for use in diabetes insipidus, when this is not of nephrogenic origin and control of bleeding from oesophageal varices. In addition, argipressin is indicated to increase blood pressure in adults with vasodilatory shock (e.g., post-cardiotomy or sepsis) who remain hypotensive despite fluids and catecholamines.

Tricosactide is a synthetic polypeptide with a corticotropin-like action. It is a corticotropin analog.

Tosactide is a synthetic peptide, a structural corticotropin analog (the first 28 amino acids of human adrenocorticotropin). The time course shows that the duration of action is short with a maximum effect at about 30 minutes and returns to a resting value soon after three hours. Tosactide has been used clinically.
