Which antacid components pose toxicity risk in CKD patients?

Which antacid components pose toxicity risk in CKD patients?

• A. Calcium-containing
• B. Aluminum-containing
• C. Magnesium-containing
• D. Both aluminum- and magnesium-containing

Answer: (D)

In CKD, reduced kidney function means the body can’t clear certain minerals from the bloodstream efficiently, so antacids containing those minerals can accumulate and cause toxicity. Aluminum-containing antacids tend to deposit in bone and brain when they build up, leading to bone disease and neurotoxicity, including encephalopathy in advanced cases. Magnesium-containing antacids can cause hypermagnesemia; as magnesium levels rise, patients may develop weakness, hypotension, slowed reflexes, and in severe cases, cardiac or respiratory depression. Calcium-containing antacids can raise calcium levels and contribute to vascular calcification, but their toxicity risk is not as high or acutely toxic as the aluminum and magnesium forms in CKD. Therefore, the components that pose the clearest toxicity risk in CKD are aluminum- and magnesium-containing antacids.
