Study Summary

It is hypothesized that zirconium silicate is safe and well tolerated and more effective than placebo (alternative hypothesis) in lowering serum potassium levels in subjects with serum potassium between 5 - 6.0 mmol/l versus no difference between zirconium silicate and placebo (null hypothesis). It is hypothesized that zirconium silicate even up to the top dose of 10g three times a day is well tolerated.

Primary Outcome

The rate of fall in S-K levels during the initial 48 hours of study drug treatment between the placebo treated subjects and the ZS treated subjects measured on a log scale
