(i) Prolonged use of aluminum-containing antacids in patients with renal failure may result in or worsen dialysis osteomalacia. Elevated tissue aluminum levels contribute to the development of the dialysis encephalopathy and osteomalacia syndromes. Small amounts of aluminum are absorbed from the gastrointestinal tract and renal excretion of aluminum is impaired in renal failure. Aluminum is not well removed by dialysis because it is bound to albumin and transferrin, which do not cross dialysis membranes. As a result, aluminum is deposited in bone, and dialysis osteomalacia may develop when large amounts of aluminum are ingested orally by patients with impaired renal function.\n\n(ii) Aluminum forms insoluble complexes with phosphate in the gastrointestinal tract, thus decreasing phosphate absorption. Prolonged use of aluminum-containing antacids by normophosphatemic patients may result in hypophosphatemia if phosphate intake is not adequate. In its more severe forms, hypophosphatemia can lead to anorexia, malaise, muscle weakness, and osteomalacia.\n\n(b) Professional labeling for an antacid-antiflatulent combination may contain the information allowed for health professionals for antacids and antiflatulents."]], "truncated": false, "filtered_table_rows_count": 8, "expanded_columns": [], "expandable_columns": [], "columns": ["section_id", "title_number", "title_name", "chapter", "subchapter", "part_number", "part_name", "subpart", "subpart_name", "section_number", "section_heading", "agency", "authority", "source_citation", "amendment_citations", "full_text"], "primary_keys": ["section_id"], "units": {}, "query": {"sql": "select section_id, title_number, title_name, chapter, subchapter, part_number, part_name, subpart, subpart_name, section_number, section_heading, agency, authority, source_citation, amendment_citations, full_text from cfr_sections where \"part_number\" = :p0 and \"title_number\" = :p1 order by section_id limit 101", "params": {"p0": "331", "p1": "21"}}, "facet_results": {"title_number": {"name": "title_number", "type": "column", "hideable": false, "toggle_url": "/openregs/cfr_sections.json?part_number=331&title_number=21", "results": [{"value": 21, "label": 21, "count": 8, "toggle_url": "https://www.pawtectors.org/openregs/cfr_sections.json?part_number=331", "selected": true}], "truncated": false}, "agency": {"name": "agency", "type": "column", "hideable": false, "toggle_url": "/openregs/cfr_sections.json?part_number=331&title_number=21", "results": [{"value": "FDA", "label": "FDA", "count": 8, "toggle_url": "https://www.pawtectors.org/openregs/cfr_sections.json?part_number=331&title_number=21&agency=FDA", "selected": false}], "truncated": false}, "part_number": {"name": "part_number", "type": "column", "hideable": false, "toggle_url": "/openregs/cfr_sections.json?part_number=331&title_number=21", "results": [{"value": "331", "label": "331", "count": 8, "toggle_url": "https://www.pawtectors.org/openregs/cfr_sections.json?title_number=21", "selected": true}], "truncated": false}}, "suggested_facets": [{"name": "subpart", "toggle_url": "https://www.pawtectors.org/openregs/cfr_sections.json?part_number=331&title_number=21&_facet=subpart"}, {"name": "subpart_name", "toggle_url": "https://www.pawtectors.org/openregs/cfr_sections.json?part_number=331&title_number=21&_facet=subpart_name"}, {"name": "amendment_citations", "toggle_url": "https://www.pawtectors.org/openregs/cfr_sections.json?part_number=331&title_number=21&_facet=amendment_citations"}], "next": null, "next_url": null, "private": false, "allow_execute_sql": true, "query_ms": 571.2914400501177, "source": "Federal Register API & Regulations.gov API", "source_url": "https://www.federalregister.gov/developers/api/v1", "license": "Public Domain (U.S. Government data)", "license_url": "https://www.regulations.gov/faq"}
