摘要：

The bioavailability of potassium from a sustained-release KC1 preparation has been compared in 10 healthy volunteers with that of a non-sustained-release KC1 coated tablet by means of urinary elimination data. From the 40 mEq KC1 additionally administered, 35.2 mEq (88%) and 35.5 mEq (88.8%) respectively were eliminated by the kidneys. On the evidence of this elimination data the sustained-release potassium preparation showed the same bioavailability as the non-sustained-release KC1 tablets. The retard form was excellently tolerated.
