Dronedarone and Prestalia

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Using dronedarone together with amLODIPine can increase the blood levels and effects of both medications. This may increase the risk of serious side effects such as irregular heart rhythm, fluid retention, swelling, heart failure, and excessively low blood pressure. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. You should seek immediate medical attention if you experience sudden, unexplained weight gain; swelling of the hands, ankles, or feet; irregular or slow heartbeat; chest pain; or difficulty breathing during treatment with these medications. Avoid driving or operating hazardous machinery until you know how the medications affect you, and use caution when getting up from a sitting or lying position. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

MONITOR: Coadministration of dronedarone and a calcium channel blocker (CCB) may result in increased plasma concentrations of both drugs. Dronedarone and most CCBs are substrates of CYP450 3A4. In addition, dronedarone and certain CCBs such as diltiazem and verapamil are also moderate inhibitors of the isoenzyme, thus competitive and noncompetitive metabolic inhibition may occur. According to the product labeling, dronedarone increased systemic exposure (AUC) to diltiazem, nifedipine and verapamil by 1.4- to 1.5-fold, while diltiazem and verapamil increased dronedarone AUC by approximately 1.4- to 1.7-fold. Pharmacodynamically, CCBs with depressant effects on the sinus and AV nodes (particularly diltiazem, verapamil, and bepridil) could also potentiate dronedarone's effects on cardiac conduction.

MANAGEMENT: Caution is advised if dronedarone is coadministered with a CCB. The dosage of the CCB should start low and increased only after ECG verification of good tolerability. Patients should be advised to promptly report potential symptoms of toxicity such as excessive fatigue; edema or swelling of the lower extremities; sudden, unexplained weight gain; fainting; difficulty breathing; chest pain or tightness; bradycardia; arrhythmia; or hypotension as indicated by dizziness, fainting, or orthostasis.
