Treating proximal renal tubular acidosis requires a structured, stepwise approach. Both the sequencing of interventions and the selection of appropriate alkali formulations are critical to achieving a safe and effective outcome.
Management centers on alkali replacement therapy to correct ongoing bicarbonate losses. There is a required preparatory step addressing electrolyte status that must be completed before alkali supplementation is initiated — the specific sequencing, the available formulations, and the rationale behind this order are detailed in the full protocol.

Treatment of proximal RTA is centered on replacing the excreted bicarbonate, typically requiring as much as 20 mEq/kg/day.
This can be done through a variety of formulations, including sodium bicarbonate tablets, sodium or potassium citrate, and baking soda.
Hypokalemia should be corrected before starting bicarbonate replacement therapy because treatment results in bicarbonaturia and resultant kaliuresis as previously described.
