Possible Interaction: Potassium and Vasoconstrictor Agents

Research Papers that Mention the Interaction

Direct vasoconstrictive effects of hypokalemia may contribute to the pressor effect of potassium depletion.
Journal of the American Society of Nephrology : JASN  •  1990  |  View Paper
High potassium intake partially abolished the vasoconstrictor effect of ouabain and also significantly increased baroreceptor reflex sensitivity.
Clinical and experimental hypertension. Part A, Theory and practice  •  1985  |  View Paper
In normotensive blacks but not whites, a marginally reduced dietary intake of potassium reversibly enhances adrenergically mediated vasopressor responsiveness to stress.
Hypertension  •  1997  |  View Paper
This increases potassium efflux, inhibits voltage-gated calcium channels, and finally overrides systemic vasoconstriction.
Critical care medicine  •  2012  |  View Paper
Increasing media potassium concentration from 5 to 30 mM resulted in a marked renal vasoconstriction decreasing renal perfusate flow by 61 +/- 4%.
The American journal of physiology  •  1989  |  View Paper
Isoproterenol (10−9 to 10−8 M) or an elevation of the bath potassium concentration from 5.9 to 11 mM significantly augmented coronary vasoconstriction induced by lowering bath Po2 from 95% to 40%.
Circulation research  •  1985  |  View Paper
The addition of a potent vasoconstrictor , such as norepinephrine, induces an influx of sodium and an efflux of calcium and potassium in the parenchymal cells of the perfused liver.
