Study (n=8)

Usual Pediatric Dose for Renal Tubular Acidosis

Study (n=8)

Renal Dose Adjustments

The use of potassium citrate in patients with chronic renal failure should be avoided due to the risk of hyperkalemia and cardiac arrest.

Liver Dose Adjustments

Data not available

Dose Adjustments

Dosage changes should occur after evaluation of results from twenty-four hour urinary citrate and/or urinary pH measurements.

Measure urinary pH and/or urinary citrate every 4 months during duration of therapy in adults.

Precautions

Treatment should be discontinued if there is hyperkalemia, a significant rise in serum creatinine, or a significant fall in blood hematocrit or hemoglobin. Serum electrolytes (sodium, potassium, chloride and carbon dioxide), serum creatinine, and complete blood count should be monitored every four months.

Dialysis

Other Comments

Potassium citrate is used to restore normal urinary citrate (320 mg/day and as close to the normal mean of 640 mg/day), and to increase urinary pH to a level of 6.0 to 7.0.

Patients should be encouraged to drink plenty of fluids per day, to reach a goal of at least 2 liters of urine per day.
