* Serum albumin \>= 2 g/dL
* Sodium, potassium, calcium and magnesium within 1.5 x institutional lower limit of normal (LLN) or ULN
* Participants must have cholesterol level \< 350 mg/dL and triglycerides \< 400 mg/dL before starting therapy. In case one or both of these are exceeded, the participant can only be included after initiation of appropriate lipid lowering medication and documentation of cholesterol \< 350 mg/dL and triglycerides \< 400mg/dl before start of therapy
* Participants with seizure disorder may be enrolled if well controlled. Participants must be on non-enzyme inducing anticonvulsants which are not excluded on study therapy
