Interaction Effect
Reduced rosuvastatin exposure and reduced efficacy of rosuvastatin
Interaction Summary
Coadministration of an antacid (aluminum and magnesium hydroxide combination) with rosuvastatin 40 mg single dose resulted in a 50% decrease in rosuvastatin plasma concentrations. There were no clinically significant changes in plasma concentrations of rosuvastatin when the antacid and rosuvastatin were given 2 hours apart. Hence, in patients taking antacids, administer rosuvastatin at least 2 hours after the antacid.

How To Manage Interaction
Coadministration of rosuvastatin and antacids decreases rosuvastatin exposure. Hence, in patients taking antacids, administer rosuvastatin at least 2 hours after the antacid.
Mechanism Of Interaction
Reduced rosuvastatin absorption

Rosuvastatin Overview
-
Rosuvastatin is used together with diet, weight-loss, and exercise to reduce the risk of heart attack and stroke and to decrease the chance that heart surgery will be needed in people who have heart disease or who are at risk of developing heart disease. Rosuvastatin is also used to decrease the amount of cholesterol such as low-density lipoprotein (LDL) cholesterol ('bad cholesterol') and triglycerides in the blood and to increase the amount of high-density lipoprotein (HDL) cholesterol ('good cholesterol') in the blood. Rosuvastatin may also be used together with diet to decrease the amount of cholesterol and other fatty substances in the blood in children and teenagers 8 to 17 years of age who have familial heterozygous hypercholesterolemia (an inherited condition in which cholesterol cannot be removed from the body normally). Rosuvastatin is used together with diet, and alone or in combination with other medications, to decrease the amount of cholesterol and other fatty substances in the blood in adults and children and teenagers 7 to 17 years of age who have familial homozygous hypercholesterolemia (an inherited condition in which cholesterol cannot be removed from the body normally). Rosuvastatin is in a class of medications called HMG-CoA reductase inhibitors (statins). It works by slowing the production of cholesterol in the body to decrease the amount of cholesterol that may build up on the walls of the arteries and block blood flow to the heart, brain, and other parts of the body.
-
Accumulation of cholesterol and fats along the walls of your arteries (a process known as atherosclerosis) decreases blood flow and, therefore, the oxygen supply to your heart, brain, and other parts of your body. Lowering your blood level of cholesterol and fats with rosuvastatin has been shown to prevent heart disease, angina (chest pain), strokes, and heart attacks.
Magnesium Oxide Overview
-
Magnesium is an element your body needs to function normally. Magnesium oxide may be used for different reasons. Some people use it as an antacid to relieve heartburn, sour stomach, or acid indigestion. Magnesium oxide also may be used as a laxative for short-term, rapid emptying of the bowel (before surgery, for example). It should not be used repeatedly. Magnesium oxide also is used as a dietary supplement when the amount of magnesium in the diet is not enough. Magnesium oxide is available without a prescription.

Definitions
Severity Categories
Contraindicated
These drugs, generally, should not be used together simultaneously due to the high risk of severe adverse effects. Combining these medications can lead to dangerous health outcomes and should be strictly avoided unless otherwise instructed by your provider.
Major
This interaction could result in very serious and potentially life-threatening consequences. If you are taking this drug combination, it is very important to be under close medical supervision to minimize severe side effects and ensure your safety. It may be necessary to change a medication or dosage to prevent harm.
Moderate
This interaction has the potential to worsen your medical condition or alter the effectiveness of your treatment. It's important that you are monitored closely and you potentially may need to make adjustments in your treatment plan or drug dosage to maintain optimal health.
Minor
While this interaction is unlikely to cause significant problems, it could intensify side effects or reduce the effectiveness of one or both medications. Monitoring for changes in symptoms and your condition is recommended, and adjustments may be made if needed to manage any increased or more pronounced side effects.
Onset
Rapid: Onset of drug interaction typically occurs within 24 hours of co-administration.
Delayed: Onset of drug interaction typically occurs more than 24 hours after co-administration.
Evidence
Level of documentation of the interaction.
Established: The interaction is documented and substantiated in peer-reviewed medical literature.
Theoretical: This interaction is not fully supported by current medical evidence or well-documented sources, but it is based on known drug mechanisms, drug effects, and other relevant information.
How To Manage The Interaction
