Minor

magnesium hydroxide moexipril

Applies to: Pedia-Lax Chewable Tablets (magnesium hydroxide) and moexipril

Coadministration with antacids may decrease the oral bioavailability of captopril and other angiotensin converting enzyme (ACE) inhibitors due to delayed gastric emptying and/or elevated gastric pH. In 10 healthy volunteers, 50 mL of an antacid suspension decreased the mean peak plasma concentration (Cmax) and area under the concentration-time curve (AUC) of captopril (50 mg single oral dose) by 50% and 42%, respectively, compared to administration after fasting. The relative bioavailability of captopril was 0.66 with antacid, although its hypotensive activity did not seem to be affected. Based on available data, the clinical significance of this interaction appears to be minor. As a precaution, patients may want to consider separating the administration times of ACE inhibitors and antacids or oral medications that contain antacids (e.g., didanosine buffered tablets or pediatric oral solution) by 1 to 2 hours.

Drug and food interactions

Moderate

moexipril food

Applies to: moexipril

GENERALLY AVOID: Moderate-to-high dietary intake of potassium can cause hyperkalemia in some patients who are using angiotensin converting enzyme (ACE) inhibitors. In some cases, affected patients were using a potassium-rich salt substitute. ACE inhibitors can promote hyperkalemia through inhibition of the renin-aldosterone-angiotensin (RAA) system.

MANAGEMENT: It is recommended that patients who are taking ACE inhibitors be advised to avoid moderately high or high potassium dietary intake. Particular attention should be paid to the potassium content of salt substitutes.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
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.
Unknown No interaction information available.
