Using EffCaMgCit to prevent complications from long-term PPI use

Effervescent Calcium Magnesium Citrate to Prevent Mineral Metabolism and Renal Complications of Chronic Proton Pump Inhibitor Therapy

Phase 3 Interventional University of Texas Southwestern Medical Center · NCT05998863

This study is testing if an effervescent supplement called EffCaMgCit can help prevent bone loss, low magnesium levels, and kidney problems in people who have been using proton pump inhibitors for a long time.

What this trial studies

This clinical trial investigates the effectiveness of effervescent calcium magnesium citrate (EffCaMgCit) in preventing osteoporosis, hypomagnesemia, and chronic kidney disease (CKD) associated with long-term use of proton pump inhibitors (PPIs). Over the course of one year, participants will receive either EffCaMgCit or a placebo, with the primary focus on measuring changes in bone mineral density, magnesium levels, and kidney function. The study aims to provide definitive evidence on whether EffCaMgCit can mitigate these complications in patients taking PPIs.

Who should consider this trial

Good fit: Ideal candidates are adults over 21 who have been taking PPIs regularly for at least two months and have controlled stage 1 hypertension and diabetes.

Not a fit: Patients with end-stage renal failure, uncontrolled diabetes, or those on certain medications that affect mineral metabolism may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce the risk of osteoporosis, magnesium deficiency, and CKD in patients on long-term PPI therapy.

How similar studies have performed: While the approach of using EffCaMgCit is novel, similar studies have indicated that addressing mineral deficiencies can improve outcomes in patients on long-term PPIs.
