- Associated Therapies
- Contraindications & Blackbox Warnings
Avoid life-threatening adverse drug eventsImprove clinical decision support with information on contraindications & blackbox warnings, population restrictions, harmful risks, & more.Avoid life-threatening adverse drug events & improve clinical decision support.- Pharmacodynamics
Neutralizes acid in the stomach 5.
- Mechanism of action
Magnesium carbonate reacts with hydrochloric acid in the stomach to form carbon dioxide and magnesium chloride thus neutralizing excess acid in the stomach 5.
Target Actions Organism UGlutamate (NMDA) receptor blockerHumans - Absorption
About 40-60% of magnesium is absorbed following oral administration 5. Percent absorption decreases as dose increases.
- Volume of distribution
Vd for magnesium is 0.2-0.4L/kg 5. About 50% distributes to bone.
- Protein binding
30% of magnesium is bound to proteins 5.
- Metabolism
Magnesium does not appear to be metabolized in any way 5.
- Route of elimination
Primarily eliminated in urine 5.
- Half-life
Half life of 27.7 hours reported with overdose of 400mEq of magnesium in an adult 5.
- Clearance
Maximum magnesium clearance is directly proportional to creatinine clearance 5.
- Adverse Effects
Improve decision support & research outcomesWith structured adverse effects data, including: blackbox warnings, adverse reactions, warning & precautions, & incidence rates.Improve decision support & research outcomes with our structured adverse effects data.- Toxicity
During overdose, magnesium impairs neuromuscular transmission resulting in weakness and hypoflexia 5.

Drug Interaction Integrate drug-drug
interactions in your softwareAbacavir Abacavir may decrease the excretion rate of Magnesium carbonate which could result in a higher serum level. Aceclofenac Aceclofenac may decrease the excretion rate of Magnesium carbonate which could result in a higher serum level. Acemetacin Acemetacin may decrease the excretion rate of Magnesium carbonate which could result in a higher serum level. Acetaminophen Magnesium carbonate can cause a decrease in the absorption of Acetaminophen resulting in a reduced serum concentration and potentially a decrease in efficacy. Acetazolamide The risk or severity of adverse effects can be increased when Acetazolamide is combined with Magnesium carbonate. Acetophenazine Magnesium carbonate can cause a decrease in the absorption of Acetophenazine resulting in a reduced serum concentration and potentially a decrease in efficacy. Aclidinium The therapeutic efficacy of Magnesium carbonate can be decreased when used in combination with Aclidinium. Acrivastine Magnesium carbonate may decrease the excretion rate of Acrivastine which could result in a higher serum level. Acyclovir Acyclovir may decrease the excretion rate of Magnesium carbonate which could result in a higher serum level. Adefovir dipivoxil Adefovir dipivoxil may decrease the excretion rate of Magnesium carbonate which could result in a higher serum level.
