निफेडिपिन और पोसाकोनाज़ोल 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 that are CYP3A4 Substrates Mechanism and Clinical Effect(s) Posaconazole may increase the plasma concentrations of calcium channel blockers that are substrates of CYP3A4.

Prevention or Management Verapamil, Diltiazem, Nifedipine, Nicardipine, Felodipine Monitor frequently for adverse reactions and toxicity with concomitant use of posaconazole with calcium channel blockers that are CYP3A4 substrates.

Dosage reduction of the calcium channel blocker may be needed.
