Interactions between mag-64(magnesium chloride) and Declomycin (demeclocycline)
demeclocycline and magnesium chloride (Moderate Drug-Drug)
ADJUST DOSING INTERVAL: Administration of a tetracycline with aluminum, calcium, or magnesium salts significantly decreases tetracycline serum concentrations. The proposed mechanism is chelation of tetracycline by the cation, forming an insoluble complex that is poorly absorbed from the gastrointestinal tract. The interaction has also been reported with parenteral doxycycline and oral antacids.
MANAGEMENT: The administration of tetracyclines and preparations containing aluminum, magnesium, or calcium should be separated by two to three hours.
