Darunavir Tablets and Ivabradine Oral Solution

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.

Darunavir may significantly increase the blood levels and effects of ivabradine, which may result in excessive slowing of heart rate or other conduction disturbances. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Let your doctor know if you experience significant decreases in heart rate or symptoms such as dizziness, fatigue, or low blood pressure. Also seek medical attention if you develop heart palpitations, chest pressure, or worsened shortness of breath, as these may be symptoms of atrial fibrillation caused by ivabradine. 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 moderate inhibitors of CYP450 3A4 may significantly increase the plasma concentrations of ivabradine, which is primarily metabolized by the isoenzyme. According to the product labeling, administration of ivabradine with the moderate CYP450 3A4 inhibitor diltiazem (120 mg twice daily) resulted in approximately 3-fold increases in ivabradine peak plasma concentration (Cmax) and systemic exposure (AUC) compared to administration of ivabradine alone. Likewise, administration with verapamil (120 mg twice daily) increased the Cmax and AUC of ivabradine by approximately 2-fold. Grapefruit juice, another moderate CYP450 3A4 inhibitor, increased ivabradine AUC by a little over 2-fold. Elevated plasma levels of ivabradine may increase the risk of excessive bradycardia and conduction disturbances.

MANAGEMENT: Concomitant use of ivabradine with moderate CYP450 3A4 inhibitors should generally be avoided. If coadministration is required, some authorities recommend initiating ivabradine at a dosage of 2.5 mg twice daily, provided the resting heart rate is at or above 70 beats per minute and heart rate is closely monitored.
