Mechanism of proton pump inhibitors
WebClinical reports demonstrate that urinary Mg excretion is low in PPI users with hypomagnesemia, suggesting a compensatory mechanism by the kidney for malabsorption of Mg in the intestines. However, the exact mechanism by which PPIs cause impaired Mg absorption is still unknown. WebProton pump inhibitors block the hydrogen ion pumps in the oxyntic cell. They include omeprazole and lansoprazole ( Fig. 4.8 and Cases 4.1 and 4.2: 2 ). These powerful drugs …
