Cardioquin and Elvitegravir, Cobicistat, Emtricitabine, and Tenofovir Disoproxil Fumarate

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 cobicistat. Combining these medications may significantly increase the blood levels and effects of quiNIDine. This can increase the risk of serious side effects such as irregular heart rhythm and other cardiovascular problems. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects. 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 CLOSELY: Coadministration with cobicistat may significantly increase the plasma concentrations of certain antiarrhythmic agents such as amiodarone, bepridil, disopyramide, flecainide, propafenone, and quinidine. The mechanism involves inhibition of CYP450 2D6 (flecainide, propafenone) and/or 3A4 (amiodarone, bepridil, disopyramide, quinidine) metabolism, as cobicistat is a potent inhibitor of both isoenzymes. The interaction has not been specifically studied, but could conceivably lead to serious and/or life-threatening reactions including cardiac arrhythmias and other toxicities if levels are significantly increased. The use of these antiarrhythmic agents has been associated with dose-related prolongation of the QT interval, thus elevated plasma levels may potentiate the risk of ventricular arrhythmias such as ventricular tachycardia and torsade de pointes as well as cardiac arrest and sudden death.

MANAGEMENT: Caution is advised if cobicistat must be used concomitantly with antiarrhythmic agents that are primarily metabolized by CYP450 2D6 and/or 3A4. Pharmacologic response and plasma antiarrhythmic drug levels should be monitored more closely whenever cobicistat is added to or withdrawn from therapy, and the antiarrhythmic dosage adjusted as necessary.
