Mechanism of chlorpropamide antidiuresis. 1977

L Czakó, and E Nagy, and F A László

A study was made of the effect of chlorpropamide in rats with pituitary stalk lesion. It was found that the drug made the oliguric interphase more pronounced and protracted, while in the lasting polyuric phase in the absence of endogenous ADH it influenced water intake only moderately. Enhancement of the effect of exogenous ADH was observed after a 2-day chlorpropamide pretreatment. The results support the view that the presence of a small amount of endogenous ADH is necessary for chlorpropamide-antidiuresis. The drug presumably brings about the decrease in diuresis via ADH mobilization, but its peripheral effect is also enhanced.

D008236 Lypressin The porcine antidiuretic hormone (VASOPRESSINS). It is a cyclic nonapeptide that differs from ARG-VASOPRESSIN by one amino acid, containing a LYSINE at residue 8 instead of an ARGININE. Lys-vasopressin is used to treat DIABETES INSIPIDUS or to improve vasomotor tone and BLOOD PRESSURE.

D014667 Vasopressins Antidiuretic hormones released by the NEUROHYPOPHYSIS of all vertebrates (structure varies with species) to regulate water balance and OSMOLARITY. In general, vasopressin is a nonapeptide consisting of a six-amino-acid ring with a cysteine 1 to cysteine 6 disulfide bridge or an octapeptide containing a CYSTINE. All mammals have arginine vasopressin except the pig with a lysine at position 8. Vasopressin, a vasoconstrictor, acts on the KIDNEY COLLECTING DUCTS to increase water reabsorption, increase blood volume and blood pressure.
