Proton pump inhibitors (PPIs) are widely used for the control of gastric ulcer-gastritis, erosive esophagitis (gastroesophageal reflux disease), peptic ulcer disease (duodenal ulcer), and heartburn. Despite their efficacy, their use has been implicated in possibly causing fragility fractures (osteoporosis), hypomagnesemia (magnesium deficiency) and increased risk of chronic kidney disease (CKD). The current trial represents the investigators ongoing effort to discern whether these complications could be averted by effervescent calcium magnesium citrate (EffCaMgCit).
In the current proposal, the investigators wish to conduct a 1-year treatment trial, directed at obtaining more definitive evidence that EffCaMgCit overcomes all three complications of PPI. Aim 1. To test the hypothesis that EffCaMgCit would prevent/treat osteoporosis, by suppressing parathyroid function and bone resorption, thereby stabilizing bone mineral density (BMD). The critical endpoint will be overall change in BMD T-Score and Z-Score from baseline to the end of study. Secondary endpoints will be the change in serum PTH and C-terminal telopeptide (CTX). Aim 2. To test the hypothesis…
Inclusion Criteria: * Ambulatory adult subjects (\> 21 years of age) of either gender of any ethnicity * Must have taken PPI (omeprazole or equivalent ≥ 20 mg/day, ≥ three times per week, for at least 2 months) * Expected to continue at a similar dosage * Stage 1 hypertension (with systolic blood pressure \<140 and diastolic \<90) * Controlled diabetes mellitus Type II with HbA1C less than 7% Exclusion Criteria: * End-stage renal failure on dialysis * Hypercalcemia, * Hypophosphatemia (serum P \< 2.5 mg/dL) * Hypertension stage 2 or higher * Diabetes Type II with HbA1C ≥ 7% * Treatment with…
Each sachet of EffCaMgCit will contain 19 meq or 380 mg calcium, 10 meq (122 mg) magnesium, and 50 meq total citrate.
Each sachet of Placebo will contain microcrystalline cellulose, but no calcium, magnesium or citrate.
