I was intrigued to know that among the indications of Renal Replacement Therapy was included high potassium levels despite proper low-potassium diet.

I remembered there are many cheap potassium-wasting diuretics, and wondered if they couldn't be used for a while in order to delay dialysis..?


it is not the absolute potassium level that is important but the presence of symp and signs of k toxicity. so in the absence of toxity one can use k wasting drugs like kayexalate which binds it in the gut and prevents its absorption.

once there are s and s of toxity, we buy time by giving calcium. GKI ( glu, k, insulin) but dialysis is inevitable cos the calcium only protects heart and GKI only redistributes the k but does not get rid of it.


What about drugs like furosemide? I have seen my share of hypokaliemias because of it...
