64 for KCIT and 0.51 for AA (p=0.077), and the median increase in citrate from baseline was 231 mg for KCIT and 171 mg for AA (p=0.109). When switching alkali therapy, median pH and citrate did not significantly change. Hyperkalemia (24%), GI upset (19%), and cost (17%) were the most common reasons cited for switching to an AA. AA represented a savings of 86-92% compared to KCIT. CONCLUSIONS Alternative alkalinizing agents appear to offer comparable improvements in 24-hour urine parameters and significant cost-saving
