MagDelay (calcium carbonate / magnesium chloride) Disease Interactions

There are 2 disease interactions with MagDelay (calcium carbonate / magnesium chloride):

Major

Magnesium Iv (Includes MagDelay) ↔ Cardiac Disease

Severe Potential Hazard, High plausibility

Applies to: Heart Block, Myocardial Infarction

The parenteral administration of magnesium is contraindicated in patients with heart block or heart damage from myocardial infarction. These conditions may be exacerbated during magnesium infusion. High serum levels of magnesium (> 4.5 mEq/L) can cause sinus bradycardia, AV block, nodal rhythms, and bundle branch block, which can progress to asystole and cardiac arrest at magnesium levels of approximately 14 mEq/L to 15 mEq/L. If parenteral magnesium is used in patients with preexisting conduction disturbances, it should be infused at a slower rate, and cardiac function and serum magnesium level should be closely monitored. The usual precautionary measures should be observed to prevent hypermagnesemia, and IV calcium salts (e.g., calcium gluconate), pressors, cardiac pacemakers, and equipment for supportive care should be immediately available in case of acute magnesium intoxication.

Magnesium Salts (Includes MagDelay) ↔ Renal Dysfunction

Severe Potential Hazard, High plausibility

Applies to: Renal Dysfunction

Magnesium is eliminated by the kidney. The serum concentration of magnesium is increased in patients with renal impairment. Magnesium toxicity includes CNS depression, muscular paralysis, respiratory depression, hypotension and prolonged cardiac conduction time. Disappearance of the patellar reflex is a useful clinical sign of magnesium intoxication. Therapy with magnesium should be administered cautiously and dosages should be modified in patients with compromised renal function. Clinical monitoring of serum magnesium levels is recommended.

Drug Interaction Classification

The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.

Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
