WebChlorpropamide may produce hyponatremia because it augments the action of vasopressin in the kidney, promoting water retention. This has resulted in its use in cranial diabetes insipidus. The mechanism underlying this action is unclear, but it is reported to be a weak inverse agonist for the V2 vasopressin renal receptor. Webc) It is metabolised by oxidative enzymes to an alcohol or carboxylic acid. The resulting polar metabolites are rapidly excreted. d) It increases the rate of N-oxidation and deactivation of the drug.
