Which drug is known to interact with Phosphorus?

Antacids are known to interact with phosphorus due to their ability to alter the absorption of dietary minerals and electrolytes in the gastrointestinal tract. Many antacids, particularly those containing aluminum, can bind to phosphorus, leading to decreased phosphate absorption. This interaction is especially relevant in populations such as older adults who may be on chronic antacid therapy and are at risk for phosphate depletion, potentially leading to conditions such as hypophosphatemia.

While ethanol and laxatives can have their own effects on various nutrients and minerals, they do not have the same specific interaction with phosphorus as antacids do. Ethanol can affect nutritional status but does not directly bind to phosphorus. Likewise, the primary action of laxatives is to stimulate bowel movements and can influence absorption to a lesser extent but do not directly interact with phosphorus levels in the same way antacids do. Therefore, antacids are specifically noted for their role in influencing phosphorus absorption, making them the most pertinent option among the choices provided.
