(Newest replies first)

I was looking for information and discounts on Potassium chloride SA 10 meq CR capsules and only found info on Potassium chloride ER. What is the difference? What does the SA mean?

These are all just abbreviations that designate it as being a time released formulation, the CR stands for controlled release, SA stands for Sustained Action, and ER stands for Extended Release. There are actually many different abbreviations that are used, but they all mean the same thing. Unfortunately, this results in a lot of confusion for many doctors and patients.

If you read the NIH research studies, you will see that such large doses of potassium cannot be taken in just one dose due to how harsh they are on the stomach, thus all such prescription tablets are time released. The harshness is also why you are usually instructed to make sure to take it with food, even if it's just a small snack.

Thus, you can pick the cheapest you can find, and not worry about it, unless your doctor says otherwise.

Is there anything else I can help with?
