ड्रोनेडेरोन और निफेडिपिन का इंटरैक्शन

…as ketoconazole, fluconazole, itraconazole, clarithromycin, erythromycin (Azithromycin, although structurally related to the class of macrolide antibiotic is void of clinically relevant CYP3A4 inhibition), grapefruit, nefazodone, fluoxetine, saquinavir, indinavir, nelfinavir, and ritonavir may result in increased exposure to nifedipine when co-administered.

Verapamil: Verapamil, a CYP3A inhibitor, can inhibit the metabolism of nifedipine and increase the exposure to nifedipine during concomitant therapy.

Non-Cardiovascular Drugs Antifungal Drugs Ketoconazole, itraconazole and fluconazole are CYP3A inhibitors and can inhibit the metabolism of nifedipine and increase the exposure to nifedipine during concomitant therapy.

Erythromycin: Erythromycin, a CYP3A inhibitor, can inhibit the metabolism of nifedipine and increase the exposure to nifedipine during concomitant therapy.

Antiviral Drugs Amprenavir, atanazavir, delavirine, fosamprinavir, indinavir, nelfinavir and ritonavir, as CYP3A inhibitors, can inhibit the metabolism of nifedipine and increase the exposure to nifedipine.

• Calcium channel blockers (CCB): Initiate CCB with low dose and increase after ECG verification of tolerability.

Calcium Channel Blockers Calcium channel blockers with depressant effects on the sinus and AV nodes could potentiate dronedarone's effects on conduction.

Give a low dose of calcium channel blockers initially and increase only after ECG verification of good tolerability [see Drug Interactions (7.3) , Clinical Pharmacology (12.3) ] .

Calcium Channel Blockers Verapamil and diltiazem are moderate CYP3A inhibitors and increase dronedarone exposure.

Calcium Channel Blockers Dronedarone increased the exposure of calcium channel blockers (verapamil, diltiazem or nifedipine).
