Cardioquin and Miconazole Buccal mucosa

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.

Talk to your doctor before using quiNIDine together with miconazole. Combining these medications may significantly increase the blood levels and effects of quiNIDine in rare cases. High blood levels of quiNIDine can occasionally cause an irregular heart rhythm that may be serious. 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 develop sudden dizziness, lightheadedness, fainting, ringing in the ears, hearing loss, vision problems, diarrhea, and/or fast or pounding heartbeats during treatment with quiNIDine. 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.

GENERALLY AVOID: Coadministration with potent inhibitors of CYP450 3A4 including azole antifungal agents may significantly increase the plasma concentrations of quinidine, which is primarily metabolized by the isoenzyme. The use of quinidine has been associated with dose-related prolongation of the QT interval, thus elevated plasma levels of the drug may potentiate the risk of ventricular arrhythmias such as ventricular tachycardia and torsade de pointes as well as cardiac arrest and sudden death. The interaction has not been studied with clotrimazole troches or miconazole buccal tablets. Although systemic absorption following mucous membrane exposure is limited, the potential for interaction with drugs metabolized by CYP450 3A4 such as quinidine cannot be ruled out.

MANAGEMENT: Given the potential for serious and life-threatening adverse cardiac events associated with increased plasma levels of quinidine, the concomitant use with clotrimazole or miconazole mucous membrane preparations should be avoided if possible. Otherwise, patients should be cautioned about the potential for interaction and advised to seek medical attention if they experience signs and symptoms that could indicate quinidine toxicity such as tinnitus, hearing loss, visual disturbances, diarrhea, dizziness, weakness, headache, syncope, and rapid or irregular heartbeats.
