Potassium chloride: absorption and excretion.

The absorption of potassium chloride in liquid form has been studied, using urinary excretion as an index of absorption. The excretion of potassium chloride was observed after inducing a water diuresis and administering a single dose in liquid form. There is evidence that potassium chloride in liquid form is absorbed rapidly, probably from the stomach, and hence there is a good rationale for its use where rapid absorption is needed, as in digitalis intoxication.
