The receptors most relevant to the pharmacology of vasopressors are adrenoceptors. Adrenoceptors, sometimes referred to as adrenergic receptors, interact with norepinephrine, epinephrine, and chemically similar drugs (called adrenomimetic, adrenergic, or sympathomimetic agents).
Vasopressin is a peptide hormone that increases water permeability of the kidney's collecting duct and distal convoluted tubule by inducing translocation of aquaporin-CD water channels in the plasma membrane of collecting duct cells.t is derived from a preprohormone precursor that is synthesized in the hypothalamus and stored in vesicles at the posterior pituitary. Most of it is stored in the posterior pituitary to be released into the bloodstream.
