Management: Avoid coadministration of oral magnesium salts and oral tetracyclines. Management: The nilotinib dose should be given 10 hours after or 2 hours before the H2 receptor antagonist in order to minimize the risk of a significant interaction.Nilotinib: Antacids may decrease the serum concentration of Nilotinib. Monitor patients closely for decreased antifungal effects if this combination is used. doctor or pharmacist) may already be aware of this interaction and may be monitoring you for it. Management: To avoid this potential interaction separate the administration of magnesium salts from administration of a fluoride-containing product by at least 1 hour.Multivitamins/Minerals (with ADEK, Folate, Iron): Antacids may decrease the serum concentration of Multivitamins/Minerals (with ADEK, Folate, Iron). Monitor patients closely for signs of inadequate clinical response to ketoconazole.Lanthanum: Antacids may diminish the therapeutic effect of Lanthanum. In patients requiring antacid therapy, employ magnesium-free preparations. Coadministration of bictegravir with or 2 hours after most polyvalent cation products is not recommended.Bisacodyl: Antacids may diminish the therapeutic effect of Bisacodyl. Management: Avoid concomitant use of calcium polystyrene sulfonate (rectal or oral) and magnesium-containing laxatives.Captopril: Antacids may decrease the serum concentration of Captopril. More specifically, concomitant use of sodium polystyrene sulfonate with magnesium-containing laxatives may result in metabolic alkalosis or with sorbitol may result in intestinal necrosis. Specifically, use of H2-Antagonists may cause a hyperresponse in gastrin secretion in response to secretin stimulation testing, falsely suggesting gastrinoma. Nilotinib: Histamine H2 Receptor Antagonists may decrease the serum concentration of Nilotinib. Biochem Pharmacol 1988 Aug 1;37(15):3049-53.
