OTC NCT04651088 ↗ Comparing Alkalinizing Agents Efficacy on Stone Risk in Patients on a Metabolically Controlled Diet Not yet recruiting University of Texas Southwestern Medical Center Early Phase 1 2021-12-01 The purpose of this study is to compare over the counter and alternative prescription urinary alkalinizing agents to slow release potassium citrate in their ability to modify urinary parameters associated with stone formation.
OTC NCT06819111 ↗ Role of Medication in Making Urine Less Acidic as Part of Kidney Stone Prevention NOT_YET_RECRUITING University of Texas Southwestern Medical Center PHASE1 2026-01-01 Diet and medications are the cornerstones of kidney stone prevention. Potassium citrate is a commonly prescribed medication to help prevent kidney stones by making urine less acidic. There are different forms of potassium citrate such as over-the-counter tablet or powder, and slow-release tablets that require a prescription. However, it is unknown if one form is better than the others. Therefore, we want to compare different forms of potassium citrate and find out how well they work and whether patients prefer one form over the others. The study period will last approximately 6 weeks for each participant. Patients will be instructed to take one form of potassium citrate for one week at a time followed by a washout period for one week. This process will be completed a total of three times as we seek to study the effects of three forms of potassium citrate. At the end of each trial week patients will be asked to provide urine samples and complete two surveys. Urine will need to be collected for 24 hours, which will then be examined to determine the effects that each form of potassium citrate has on urine. In addition, completed surveys will give us information on how well the medication was tolerated and their satisfaction with the treatment. There is a possibility that patients like one form better than others, and it is also possible that they do not see a difference at all. Throughout the duration of the study patients will be asked to be a directed diet. This will be based on general recommendations by the National Kidney Foundation for the prevention of kidney stones.

NCT06335537 ↗ Impact of Sodium Bicarbonate on 24-hour Urine Parameters in Hypocitriuric and Uric Acid Stone Formers RECRUITING University of California, Irvine PHASE1 2025-05-01 The incidence of kidney stone disease continues to rise globally. Although the treatment of kidney stone disease has dramatically improved in recent years, surgical management remains invasive and expensive. Patients who develop kidney stones are at high risk of recurrence during their lifetime; therefore, prevention of stones should be a primary focus. Low levels of citrate and acidic urine are risk factors for the formation of kidney stones such as calcium oxalate and uric acid, respectively. Calcium oxalate stones are the predominant stone composition in the United States, accounting for over 2/3rds of stones. Citrate is a key inhibitor of calcium oxalate crystal formation and thus increasing it in the urine of a calcium oxalate stone former is quite beneficial. Uric acid stones account for approximately 10 percent of all stone types. These stones form primarily due to an acidic urinary environment which is a prerequisite for crystal formation. Common medications for stone formers include potassium citrate which help to make the urine more alkaline. Although effective, these medications have side effects and may prove to be too expensive (upwards of $450/month). Consuming baking soda (sodium bicarbonate) may prove to be an inexpensive ($0.34/month) equally effective alternative with respect to increasing urinary citrate levels and alkalinizing the urine. Investigators hypothesize that twice a day oral baking soda in a liquid medium (e.g., water, orange juice, soda, etc.) can be an effective, and inexpensive alternative to urocit K with regard to alkalinizing the urine and raising urinary citrate levels.
