What is the difference between k-citrate and ca-citrate for kidney stone patients? what is faxomax?

Stones: K-Cit is better absorbed from the intestine, compared to Ca-Cit. However in patients who have poor kidney function or are on certain blood pressure medications, K-Cit can make the blood potassium increase to potentially deadly levels. The main component in both is the citrate, which is a stone inhibitor. Flomax, (tamsulosin) for stones, causes the ureter to dilate increasing chances of passing stone.
