Abstract
Chronic intake of proton pump inhibitors (PPI) has been associated with hypomagnesemia but prevalence of PPI-associated hypomagnesemia is not known. We examined the prevalence of hypomagnesemia among long-term PPI recipients using a large health maintenance organization database. We collected data on 10,167 participants eligible for chronic drug prescriptions from 2008 through 2013. Adult subjects receiving continuous PPI therapy for ≥6 months between and ≥1 serum magnesium determination were identified. Patients with any magnesium levels less than 1.6 mg/dl were selected for analysis; those with recognizable causes of altered magnesium homeostasis were excluded. Five hundred ninety participants received long-term PPIs and 414 (70.2%) met the inclusion criteria, for a total exposure of 2293 PPI-years (average 5.7 years/subject). Of these patients, 57 (13.8%) had ≥1 low serum magnesium: 5 were no longer on PPIs and 44 had other recognizable causes for hypomagnesemia (25 receiving diuretics, 8 with chronic diarrhea, 8 with chronic kidney disease, and 3 with malignancies). Of the 8 remaining patients (7 female; mean age, 71.2±13.4 years; mean daily medications, 5.4±1.1), mild hypomagnesemia (range, 1.2-1.5mg/dl) was noted in 13.9% of 289 measurements. All 8 patients had normal serum levels of magnesium at their final measurement. In the absence of known precipitating factors, chronic PPI use does not therefore appear to be associated with hypomagnesemia.
