Use
Magnesium oxide is a basic compound and as such can react with acidic compounds in the solid state to form salts such as Mg(ibuprofen)2 or degrade alkaline-labile drugs.Adsorption of various drugs onto magnesium oxide has been reported, such as antihistamines, antibiotics (especially tetracyclines),salicylates, atropine sulfate,hyoscyamine hydrobromide, paracetamol, chloroquine; and anthranilic acid derivatives have been reported to adsorb onto the surface of magnesium oxide. Magnesium oxide can also complex with polymers, e.g. Eudragit RS, to retard drug release and can interact in the solid state with phenobarbitone sodium. Magnesium oxide can also reduce the bioavailability of phenytoin,trichlormethiazide,and antiarrhythmics.The presence of magnesium oxide can also have a negative impact on the solid-state chemical stability of drugs, such as diazepam.Magnesium oxide has been used as a stabilizer for omeprazole due to its strong waterproofing effect.
