Interactions between your drugs

Moderate

estramustine trandolapril

Applies to: estramustine and trandolapril

MONITOR: The concomitant administration of estramustine and angiotensin enzyme converting (ACE) inhibitors may increase the risk of angioedema. The mechanism is unknown. Cases of angioedema have been associated with estramustine administration; many of these patients were also receiving ACE inhibitors.

MANAGEMENT: It is recommended to monitor patients for adverse reactions during concomitant therapy. Clinicians and patients should be aware of the potential for increased risk of angioedema when estramustine is prescribed with ACE inhibitors. Patients should be advised to promptly discontinue these medications and seek medical attention if they develop signs or symptoms suggestive of angioedema such as swelling of the face, extremities, eyes, lips, or tongue, and difficulty swallowing or breathing.

Drug and food interactions

Moderate

estramustine food

Applies to: estramustine

ADJUST DOSING INTERVAL: Food and milk may significantly decrease serum concentrations of estramustine. The mechanism of the interaction is not known.

MANAGEMENT: It is recommended that estramustine be taken at least 1 hour before or 2 hours after meals, and that it not be coadministered with milk, or calcium containing products.

trandolapril food

Applies to: trandolapril

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.
