INTERACTIONS: Antacids Concurrent use of antacids with citrates may result in systemic alkalosis. Concomitant administration of antacids with sodium citrate and sodium bicarbonate may promote the development of calcium stones in patients with uric acid stones and may also cause hypernatraemia. Concurrent use of aluminium-containing antacids with citrate salts can increase aluminium absorption, possibly resulting in acute aluminium toxicity, especially in patients with renal insufficiency. Quinolones Citrates may reduce the solubility of ciprofloxacin, norfloxacin, or ofloxacin in the urine. Patients should be observed for signs of crystalluria and nephrotoxicity. Salicylates
